Kan een afbeelding zijn van hond

Dit is ons nieuw hondje Kira, een kruising van een waterhond en een Podenko. Ze is sinds 7 februari 2024 bij ons en druk bezig ons hart te veroveren. Het is een lief, aanhankelijk hondje, dat zich op een week snel aan ons heeft aangepast. Ze is heel vinnig en nieuwsgierig, een heel ander hondje dan Noleke.

This is our new dog Kira, a cross between a water dog and a Podenko. She has been with us since February 7, 2024 and is busy winning our hearts. She is a sweet, affectionate dog who quickly adapted to us within a week. She is very quick and curious, a very different dog than Noleke.

    UFO's of UAP'S in België en de rest van de wereld
    In België had je vooral BUFON of het Belgisch UFO-Netwerk, dat zich met UFO's bezighoudt. BEZOEK DUS ZEKER VOOR ALLE OBJECTIEVE INFORMATIE , enkel nog beschikbaar via Facebook en deze blog. Verder heb je ook het Belgisch-Ufo-meldpunt en Caelestia, die prachtig, doch ZEER kritisch werk leveren, ja soms zelfs héél sceptisch... Voor Nederland kan je de mooie site www.ufowijzer.nl bezoeken van Paul Harmans. Een mooie site met veel informatie en artikels. MUFON of het Mutual UFO Network Inc is een Amerikaanse UFO-vereniging met afdelingen in alle USA-staten en diverse landen. MUFON's mission is the analytical and scientific investigation of the UFO- Phenomenon for the benefit of humanity... Je kan ook hun site bekijken onder www.mufon.com. Ze geven een maandelijks tijdschrift uit, namelijk The MUFON UFO-Journal. Since 02/01/2020 is Pieter ex-president (=voorzitter) of BUFON, but also ex-National Director MUFON / Flanders and the Netherlands. We work together with the French MUFON Reseau MUFON/EUROP. ER IS EEN NIEUWE GROEPERING DIE ZICH BUFON NOEMT, MAAR DIE HEBBEN NIETS MET ONZE GROEP TE MAKEN. DEZE COLLEGA'S GEBRUIKEN DE NAAM BUFON VOOR HUN SITE... Ik wens hen veel succes met de verdere uitbouw van hun groep. Zij kunnen de naam BUFON wel geregistreerd hebben, maar het rijke verleden van BUFON kunnen ze niet wegnemen...

    Krijgen we binnenkort een adembenemend verschijnsel te zien? Gigantische ster Betelgeuse staat mogelijk op springen - HLN.be

    Bron: space.com, Forbes, Science Alert

    Een illustratie van Betelgeuse en de gaspluim errond.
     Wetenschappers kijken met ingehouden adem naar Betelgeuse. De gigantische ster, zo’n 1.400 keer groter dan onze zon, vertoont abnormaal gedrag en staat mogelijk op springen. Een explosie van Betelgeuse zou de meest nabije supernova sinds de 17e eeuw zijn en een fenomenaal spektakel opleveren op aarde.

    Astronomen schatten eerder dat Betelgeuse nog zo’n 100.000 jaar zou leven, een eeuwigheid voor ons maar een luttel moment voor het heelal. Maar intussen hebben wetenschappers bizar gedrag vastgesteld bij Betelgeuse. De snelheid waarmee de ster uitdooft, is plots hoger dan ooit tevoren. Dat betekent dat er mogelijk een supernova van ongeziene omvang zit aan te komen.

    Betelgeuse is zo groot dat de ster het grootste deel van ons zonnestelsel zou innemen, van Mercurius tot Jupiter.

     ALMA 
    Betelgeuse is zo groot dat de ster het grootste deel van ons zonnestelsel zou innemen, van Mercurius tot Jupiter.

    Kloppend hart

    Betelgeuse is een beetje te vergelijken met een kloppend hart: de ster dooft uit en wakkert weer aan in golvende bewegingen. Volgens nieuwe data van astronoom Edward Guinan van de Villanova University in de Amerikaanse staat Pennsylvania zit Betelgeuse mogelijk in een uitdoofperiode van 430 dagen. Op 21 februari loopt die periode af en zal Betelgeuse donkerder dan ooit tevoren zijn. Die dag wordt cruciaal, want als de ster daarna niet weer opwakkert en verder uitdooft, stevenen we mogelijk af op een supernova. Dan explodeert de ster.

    Wat als Betelgeuse echt op springen staat?

    Betelgeuse bevindt zich op 700 lichtjaren van de aarde. Ter vergelijking: onze zon ligt op ongeveer 8,3 lichtminuten van de aarde en dus bijna 5 miljoen keer dichter. Betelgeuse ligt dus ver genoeg om geen gevaar te vormen voor ons, maar wel dicht genoeg om de meest nabije supernova in 400 jaar te worden.

    De kans blijft weliswaar gering dat wij Betelgeuse zien ontploffen. Betelgeuse is al vaak gedimd en de kans is klein dat het deze keer wel tot een supernova komt.

    Mogelijk is Betelgeuse trouwens al lang ontploft, maar net omdat de ster zo ver van ons ligt, krijgen wij ze te zien zoals ze er 700 jaar geleden uitzag, want dat is de tijd die het licht nodig heeft om van Betelgeuse tot bij ons te geraken. Als wij de supernova ooit te zien krijgen, zal Betelgeuse al een eeuwigheid zijn uitgedoofd.

    Hoe zal die explosie eruitzien?

    Als Betelgeuse ontploft, krijgen we een prachtig spektakel te zien op aarde dat mogelijk tot enkele dagen kan duren. De supernova wordt zo helder dat hij zelfs overdag te zien zal zijn. Het licht wordt wellicht zelfs helderder dan dat van de Maan. De laatste keer dat mensen een vergelijkbaar fenomeen hebben meegemaakt, is ongeveer 400 jaar geleden.

    Wetenschappers houden Betelgeuse nauwlettend in de gaten tot 21 februari, want dan weten we of de kans op een supernova echt groter wordt.

    UFO Caught At Space Station Using Infrared Cam, Video, UFO Sighting News.

    Date of sighting: Feb 7, 2020
    Location of sighting: Space Station
    Source: Live ISS Cam
     
    This UFO was captured by a new UFO hunter on Youtube going by the name of UFOgent. He captured this orb on the space station live cam and its just mind blowing. The cam is in infrared at the moment. That is why its purplish pink in color. Nothing can escape infrared video, it cuts through cloaks, clouds, water and even reflections on water, windows and tinted glass. But you probably already know that. This orb is heading towards the space station. Probably some aliens deciding to take a closer look at what the astronauts on board are doing and thinking. Some might say this is the moon. That would come from an inexperienced person who has not used the live cam very much. I have used it for over 15 years...and me and Streetcap1 were the founding fathers at using this cam to find UFOs. The Russians killed him, so that just leaves me. So when I say this is not the moon, you can trust me. Its also too slow to be a meteor.

    61% Of People Want The U.S. Government To Make Information On UFOs Public

    A majority of people want U.S. government information on UFOs to be made public.

    According to a study from Piplsay, 61% of people want the government to release any information it might have on UFOs and aliens to the public. (RELATED: The Trailer For ‘Westworld‘ Season 3 Has Been Released. It’s Absolutely Insane)

    The same study found that 58% of people think the government investigates UFOs and aliens, and 27% believe the sightings are real.

    I’m all in on this. I’m all in! Release the files from Area 51 and elsewhere, folks! Let the information flow through the streets and into the minds of the people!

    Ever since the Navy UFO videos of the “tic tac” became public, it seems like people are becoming more and more interested in UFOs.

    Do I think aliens and UFOs are real? Not a clue. I don’t know anything more than you guys do. Of course, a UFO doesn’t naturally mean it’s an alien.

    It just means it’s a flying object that can’t be identified. Now, is it a lot more fun to assume it’s an alien spacecraft? Sure, but that’s not what it means by default.

    Either way, I say live on the edge and declassify everything. Embrace the chaos. If the aliens are here and we need to get into some “X-Files” kind of stuff, then so be it.

    At least let us know!

    Sound off in the comments if you want the government to release their info!

    Beautiful outcome of a fight between sibling stars

    In a cosmic ‘stellar fight,’ a red giant star engulfed its smaller binary companion star. The chaos, however, created a beautiful space image.

    Blue and red rings on a black background.

    View larger. | This new image from the ALMA telescope in Chile shows the aftermath of a near-collision between stars in the binary star system HD101584. In this system, a red giant star is engulfing its smaller companion. The colors indicate velocities of gas moving toward or away from us. Blue indicates gas moving toward us. Red indicates gas moving away.

    Image via ALMA/ ESO/ NAOJ/ NRAO)/ Olofsson et al./ Robert Cumming.

    Stars like our sun die by expanding into huge, bloated red giants. Over time, some lose their outer layers gradually, leaving behind only a hot core called a white dwarf. Our sun is expected to end its life in this way. In the case of the binary star system HD101584, however, the death process was interrupted prematurely, and the result was the beautiful image shown at top. The European Southern Observatory (ESO) released this new image from the ALMA telescope in Chile on February 5, 2020. It shows what can happen when one star swallows another. 

    Hans Olofsson of the Chalmers University of Technology in Sweden, who led a recent study of this object, commented in a statement:

    The star system HD101584 is special in the sense that this ‘death process’ was terminated prematurely and dramatically as a nearby low-mass companion star was engulfed by the giant.

    Here’s what’s happening in this image. The more massive star in the HD101584 system would have expanded into a red giant faster than its less massive companion. It eventually grew large enough to swallow up its smaller companion star.

    As the smaller star became engulfed, it began to spiral in towards the core of the red giant, but never actually collided with it. Instead, the larger star experienced a massive outburst, shedding its outer gas layers.

    Jets of gas formed during this process, blasting though material previously ejected from the star, which formed the rings of gas.

    Star chart: curved grid with many black dots and colored lines.

    The double star system HD101584 is located in our sky in the direction of the constellation of Centaurus. HD101584 itself is highlighted with a red circle on this chart.

    Image via ESO.

    The nebula-like gas cloud in the new ALMA image is beautiful, and it can also provide scientists with valuable clues about how sunlike stars form and evolve. As co-author Sofia Ramstedt from Uppsala University in Sweden explained:

    Currently, we can describe the death processes common to many sunlike stars, but we cannot explain why or exactly how they happen. HD101584 gives us important clues to solve this puzzle since it is currently in a short transitional phase between better studied evolutionary stages. With detailed images of the environment of HD101584 we can make the connection between the giant star it was before, and the stellar remnant it will soon become.

    Hans Olofsson of the Chalmers University of Technology in Sweden led the study of HD101584.

    Image via Stockholm University.

    ESO said that it’s ALMA’s ability to see distant objects sharply – combined with data from the ESO-operated Atacama Pathfinder EXperiment (APEX) – that made this image possible. Elizabeth Humphries, another co-author from ESO in Chile, explained that the combination of ALMA and APEX was essential to being able to study “both the physics and chemistry in action” of the gas cloud.

    Right now, the two stars in this gas cloud can’t be resolved separately as they are too close together and too distant. Only the colorful tendrils of gas now surrounding them can be easily seen. But, ESO said, its upcoming Extremely Large Telescope, now under construction, will be able to see them more clearly for the first time. As Olofsson said, it:

    Will provide information on the ‘heart’ of the object.

    The video below – also released February 5, 2020 – is also very cool. It starts by showing a wide-field view of a region of the sky in the constellation of Centaurus, then zooms in to show HD 101584, and the beautiful gas cloud surrounding the binary star.

    Bottom line: A “stellar fight” – where a red giant star engulfed a smaller companion star – resulted in a beautiful and colorful gas cloud. Stars go through a process of birth, life, death – and even conflict – much as living things do. In this case, the cause of this cosmic display was chaotic and violent, but its result was beautiful.

The European Southern Observatory (ESO) released this new image from the ALMA telescope in Chile on February 5, 2020. It shows what can happen when one star swallows another. 

    Hans Olofsson of the Chalmers University of Technology in Sweden, who led a recent study of this object, commented in a statement:

    The star system HD101584 is special in the sense that this ‘death process’ was terminated prematurely and dramatically as a nearby low-mass companion star was engulfed by the giant.

    Here’s what’s happening in this image. The more massive star in the HD101584 system would have expanded into a red giant faster than its less massive companion. It eventually grew large enough to swallow up its smaller companion star.

    As the smaller star became engulfed, it began to spiral in towards the core of the red giant, but never actually collided with it. Instead, the larger star experienced a massive outburst, shedding its outer gas layers.

    Jets of gas formed during this process, blasting though material previously ejected from the star, which formed the rings of gas.

    The double star system HD101584 is located in our sky in the direction of the constellation of Centaurus. HD101584 itself is highlighted with a red circle on this chart.

    The nebula-like gas cloud in the new ALMA image is beautiful, and it can also provide scientists with valuable clues about how sunlike stars form and evolve. As co-author Sofia Ramstedt from Uppsala University in Sweden explained:

    Currently, we can describe the death processes common to many sunlike stars, but we cannot explain why or exactly how they happen. HD101584 gives us important clues to solve this puzzle since it is currently in a short transitional phase between better studied evolutionary stages. With detailed images of the environment of HD101584 we can make the connection between the giant star it was before, and the stellar remnant it will soon become.

    Hans Olofsson of the Chalmers University of Technology in Sweden led the study of HD101584.

    ESO said that it’s ALMA’s ability to see distant objects sharply – combined with data from the ESO-operated Atacama Pathfinder EXperiment (APEX) – that made this image possible. Elizabeth Humphries, another co-author from ESO in Chile, explained that the combination of ALMA and APEX was essential to being able to study “both the physics and chemistry in action” of the gas cloud.

    Right now, the two stars in this gas cloud can’t be resolved separately as they are too close together and too distant. Only the colorful tendrils of gas now surrounding them can be easily seen. But, ESO said, its upcoming Extremely Large Telescope, now under construction, will be able to see them more clearly for the first time. As Olofsson said, it:

    Will provide information on the ‘heart’ of the object.

    The video below – also released February 5, 2020 – is also very cool. It starts by showing a wide-field view of a region of the sky in the constellation of Centaurus, then zooms in to show HD 101584, and the beautiful gas cloud surrounding the binary star.

    Bottom line: A “stellar fight” – where a red giant star engulfed a smaller companion star – resulted in a beautiful and colorful gas cloud. Stars go through a process of birth, life, death – and even conflict – much as living things do. In this case, the cause of this cosmic display was chaotic and violent, but its result was beautiful.

    Will Humanity Achieve Interstellar Travel And Find Alien Life? - PART II

    Live blog begins at 3:50 PM Pacific Time, with all timestamps below shown beginning from that starting point.

    A representation of an alien invasion. This is not an actual extraterrestrial.

    4:00 PM: Aliens, on the other hand, are likely ubiquitous, based on what we know about the ingredients for life in the Universe, the workings of chemistry, and our measurements of exoplanets with the right conditions for life around other stars. We have literally billions and billions of potentially habitable planets in our galaxy alone, with similar conditions to early Earth. In many models, early Venus and Mars were similar to early Earth.

    Are we supposed to believe that Earth, where life arose within the first ~3% of our planet's history, is somehow unique in that regard? Although winding up with something like human beings is a difficult proposition, winding up with no life at all, across billions and billions of other instances with similar initial conditions, seems far more unlikely, at least from a scientific perspective.

    4:01 PM: Hooray for another on-time start, as Greg Dick, the executive director of Perimeter Institute, gets us started right on time with his introduction!

    4:02 PM: Oh, before I forget, Bryan is Australian, so get ready for an accent, although his won't be the strongest Australian accent you hear by a long shot!

    4:03 PM: And that's a pretty quick introduction! Here we go; curious what the scientific perspective holds, according to an astronomer/astrophysicist who isn't me!

    4:05 PM: Spoilers: we don't have warp drive yet, and we haven't found the aliens yet. Love to hear this up-front, but I also love the optimism that he has that science can make pretty much all of our non-laws-of-physics-violating dreams come true. I think, at its best, this is the dream we all have for science.

    4:07 PM: Bryan absolutely talks about an important aspect of being exposed to not just answers of what we do know, but what the frontiers of science are, what's unknown, at a young age. As a five year old, to discover that adults, parents, teachers, and even experts (libraries and encyclopedias) didn't know the answer to everything.

    And that there are people who figure out the answers to those questions, and they're just ordinary people, and that he could be one of them.

    Please note that this applies to everyone! You can do it, too, and you don't have to figure that out at age 5 to do it.

    From inflation to the hot Big Bang, to the birth and death of stars, galaxies, and black holes, all... [+] the way to our ultimate dark energy fate, we know that entropy never decreases with time. But we still don't understand why time itself flows forward. However, we're pretty certain that entropy is not the answer.

    4:10 PM: And this is a lot of fun, too: the fact that questions we didn't even know we needed to ask can be revealed by finding the answers to previous scientific questions. In the 1920s, we didn't know the Universe was expanding, but its discovery led to the idea of the Big Bang. In the 1960s, we didn't know that the Big Bang was true, but its confirmation led to questions about what came before it and what our Universe's ultimate fate would be.

    And now, as you can see, we're talking about the mysteries of cosmic inflation and dark energy, which are where those frontiers now lie. And in any field, this is how it works: discovering an answer only reveals a deeper frontier that we haven't yet explored.

    4:11 PM: I like Bryan's delineation between the difference between science and science fiction. Science is all about discovering and following the rules; science-fiction is about breaking those rules. I haven't explicitly thought about it in those terms, and I agree that this is pretty much how it usually works. I don't know that this is why I, personally, like or don't like various forms of science-fiction, but it's a new perspective to think about for me.

    4:13 PM: We constantly have advancing technology, and science-fiction asks the question of how advancing technology will change our lives. He brings up the example of Westworld, which I like, but I really think he missed a golden opportunity to reference Black Mirror, which really highlights and elevates the dystopian aspects of our society in a new way in each episode.

    An animation showing the path of the interstellar interloper now known as ʻOumuamua. The combination... [+] of speed, angle, trajectory, and physical properties all add up to the conclusion that this came from beyond our Solar System.

    4:15 PM: Alright, some science! Here we are, moving on to interstellar interloper 'Oumuamua, one of the things we've seen that wasn't particularly anticipated, even by science fiction. And yet, Bryan is correct to point out that Star Trek IV: The Voyage Home, had a cigar-shaped alien asteroid in our own solar system.

    It's not, of course, telling us to save the whales, and it's not a space probe, but it's remarkable that science fiction had this idea before astronomers or any scientists knew it was coming.

    The Event Horizon Telescope's first released image achieved resolutions of 22.5 microarcseconds,... [+] enabling the array to resolve the event horizon of the black hole at the center of M87. A single-dish telescope would have to be 12,000 km in diameter to achieve this same sharpness. Note the differing appearances between the April 5/6 images and the April 10/11 images, which show that the features around the black hole are changing over time. This helps demonstrate the importance of syncing the different observations, rather than just time-averaging them.

    4:18 PM: This one is a little bit less fair. When you're talking about older movies that talk about black holes, it's really unfair to talk about how "we knew what black holes would look like" in science-fiction, because black holes have been astrophysically theorized for decades, going back to the 60s, 50s, or even 1916 in the context of General Relativity, and even earlier (the late 18th century) in Newtonian gravity.

    Sure, it's fascinating, but visualizations, based on a mix of science and artistic license, have been around for as long as we've even known enough about science to imagine what could realistically be. Also, side note, the "interstellar" black hole is probably not very likely to be what we see when we examine our realistic black holes in supreme accuracy; there's a lot of artistic license and some likely unphysical assumptions that were made for Insterstellar.

    Artist’s illustration of two merging neutron stars. Binary neutron star systems inspiral and merge... [+] as well, but the closest orbiting pair we’ve found within our own galaxy won’t merge until nearly 100 million years have passed. LIGO will likely find many others before that.

    4:22 PM: I also don't quite think it's fair to say "well, we simulated and visualized this astrophysical event," and then "we observed it," and "that's an example of science outstripping science fiction.

    Yes, it's true that the entire Universe shook... but not every scientific event, including one that involves planet Earth "shaking" by less than an atom's width, makes for particularly good science fiction. He said earlier, remember, that science fiction was about investigating the human condition. It's hard to see how a tiny, subtle effect like that would make for a good sci-fi story.

    The hyperdrive from Star Wars appears to depict an ultra-relativistic motion through space,... [+] extremely close to the speed of light. Under the laws of relativity, you neither reach nor exceed the speed of light if you're made of matter. But you might be able to approach it if you had a large-enough amount of an efficient-enough fuel. Dark matter could fit exactly the conditions we need to make this science-fiction dream a reality.

    4:25 PM: Okay, this is a pet peeve of mine. Do you know why things like rockets and space shuttles have the shapes they do? That elongated, narrow-cone shape you're familiar with? It's because of atmospheric drag.

    If you're going to build your ship in space, and fly it only in space, you don't need to factor in aerodynamic considerations at all! You'd be much, much smarter to build a structure with a good volume-to-surface-area ratio: a sphere. The Death Star, not the Millennium Falcon or an X-Wing, is going to be much more practical for structures we build in space!

    The NEXIS Ion Thruster, at Jet Propulsion Laboratories, is a prototype for a long-term thruster that... [+] could move large-mass objects over very long timescales.

    4:28 PM: Ion drives are real, and they're very cool. But if you want to power a journey across large distances in a reasonable amount of time, ion drives won't get you far at all. They can take you ~6 billion kilometers over 11 years, as Bryan said, and can do so pretty efficiently. But if you factor that distance over that time as a "mean acceleration," you get something truly atrocious: 100 nanometers/second^2.

    You're... not going to go very far very fast. ~100,000 years to the nearest star, same as conventional fuel. I'll pass, thank you.

    Normally, structures like IKAROS, shown here, are viewed as potential sails in space. However, if a... [+] large-area object were placed between the Earth and the Sun, it could reduce the total irradiance received at the top of our atmosphere, potentially combating global warming.

    4:30 PM: Hey, solar sails! Yes, if you accelerate with a solar sail, you can decelerate with a solar sail! The "fuel" is simply radiation provided by a star, so as long as you visit a star comparable to the Sun, you could decelerate the same way you accelerated.

    Unfortunately, this technology is inferior to ion drives not only in terms of distance reached, but in terms of acceleration and control over your spacecraft. It's a nice idea, but it's an idea that's in its infancy, at best, despite being proposed more than 400 years ago by Johannes Kepler!

    4:32 PM: 75 years?! That's... that's going to assume a very light payload and a very, very large and efficient over a distance of 1.8 kilometers. Can we do that for ~4 light years, or 20 trillion kilometers. That's... well, good luck is all I'll say.

    The EmDrive device, as originally displayed by Roger Shawyer's company, SPR Limited.

    4:33 PM: Hey, don't be out of date, Bryan! The Em Drive was totally debunked a few years ago. Nice idea, but it's done.

    Quantum teleportation, an effect (erroneously) touted as faster-than-light travel. In reality, no... [+] information is being exchanged faster than light. However, the phenomenon is real, and in line with the predictions of all viable interpretations of quantum mechanics.

    4:36 PM: Remember, what "quantum teleportation" is doesn't involve teleporting a particle, it involves teleporting the quantum state of a particle. And Bryan gets that right, but this doesn't solve the problem of teleporting an inanimate object, much less a person.

    4:38 PM: Yes, you need a lot of information to encode a human being. Remember that there are around ~10^28 atoms in the human body, and that means something like 10^29 or 10^30 quantum bits of information. As Bryan says, "I don't think we'll be teleporting anytime soon."

    The travel time for a spacecraft to reach a destination if it accelerates at a constant rate of... [+] Earth's surface gravity. Note that, given enough time, you can go anywhere.

    4:40 PM: Hey, don't be mad at time dilation! Time dilation is what could get us to the stars in a human lifetime. If you wanted to go more than ~100 light-years, it would always take you more than ~100 years (a human lifetime, at the far end) to get there from the frame-of-reference of a person remaining on Earth.

    But if you continue to accelerate at 1 g, or 9.8 m/s^2, you'll get to wherever you want to go in a much shorter timescale from your frame of reference, as you travel close to the speed of light. Time dilation rules!

    An artist's conception of a starship making use of the Alcubierre drive to travel at apparently... [+] faster-than-light speeds. By combining warp technology with the mycelium drive and the ship's shields, Stamets and Tilly devise a plan to get Discovery home while keeping the mycelium network intact.

    4:42 PM: Okay, really? From long, long-term technologies like ion drives and solar sails straight to warp drive, with nothing in between? In terms of not using fuel, Bryan is correct. But in terms of not using energy... well, good luck transforming your spacetime, where (reminder) spacetime's curvature is based on matter-and-energy, without expending energy!

    The DEEP laser-sail concept relies on a large laser array striking and accelerating a relatively... [+] large-area, low-mass spacecraft. This has the potential to accelerate non-living objects to speeds approaching the speed of light, making an interstellar journey possible within a single human lifetime. The work done by the laser, applying a force as an object moves a certain distance, is an example of energy transfer from one form into another.

    4:43 PM: Wait, he's going to finish this part of his talk now, talking about Breakthrough Starshot (and the laser sail technology and a "starchip" spaceship) which we mentioned earlier, and cover "aliens" in... what, 10-15 minutes? We'll see!

    4:45 PM: Nope; we're not onto the "aliens" part yet; we're talking about femtosatellites, which are still quite large and weigh a few grams, which is still too much for Breakthrough Starshot.

    Tiny particles known as micrometeoroids will strike whatever they encounter in space, causing... [+] potentially very significant amounts of damage as a result, especially as the collisions build up over time and occur at higher speeds.

    4:48 PM: Yesss! This is something I'm excited to hear, because it's something that I've brought up that few people talk about: when you travel through space at relativistic speeds, you are going to smash into stuff in the interstellar medium! And that stuff is going to erode your spacecraft really fast, and there's nothing that's going to protect your "starship" (even if it's a microchip) from smashing into that dust.

    Remember that a little piece of nerf-like foam was all it took, at high speeds, to cause the Space Shuttle Columbia disaster. Remember that all of our spacecraft get hit by micrometeoroids. And remember that 20% the speed of light is about 100 times faster than our fastest spacecraft go, which means they have 10,000 times the kinetic energy from dust particle collisions. This is a harder problem to overcome than anyone has figured out a viable way to reckon with.

    4:50 PM: Okay, it's onto the aliens part, and I have to disagree with what Bryan says. We don't want to go to planets around other stars to look for life; we want to find planets where life exists (or is likely) and then go there.

    There are ~400 billion stars in our galaxy. Do you want to go on a wild goose chase, or do you want to know where you're going before you go on a decades-long journey across the great void of space?

    (Pick the latter.)

    When Hubble pointed at the system Kepler-1625, it found the initial transit of the main planet began... [+] an hour earlier than anticipated, and was followed by a second, smaller transit. These observations were absolutely consistent with what you'd expect for an exomoon present in the system.

    4:53 PM: Using the transit method, we can find out properties of the planets that orbit around the stars, and they come in enormous varieties, just like we'd expect if we didn't assume the rest of the Universe was just like our little corner. We've found the planets that are easiest to find, and that means the largest planets relative to their star in close-in orbits. This, unsurprisingly, has skewed the population of planets that we've found.

    Although more than 4,000 confirmed exoplanets are known, with more than half of them uncovered by... [+] Kepler, finding a Mercury-like world around a star like our Sun is well beyond the capabilities of our current planet-finding technology. As viewed by Kepler, Mercury would appear to be 1/285th the size of the Sun, making it even more difficult than the 1/194th size we see from Earth's point of view.

    4:55 PM: We have found waterworlds and lava worlds, but these are... well, likely not the best candidates for an "interesting" form of alien life. Nor are hot Jupiters (or any type of Jupiter), or any gas planet with a large hydrogen/helium envelope.

    Just like in our own Solar System, most of the planets out there are not expected to have life on them.

    4:56 PM: This is a totally unimportant point, but for an astronomer, it's a pet peeve for many.

    The smallest stars in the Universe are red dwarfs. Always dwarfs, never dwarves. The plural of dwarf (for stars) is dwarfs; the plural of dwarf (for the fantasy race of short, stout, beard, axe-wielding characters) is dwarves.

    If TOI 700d were a cloudless, dry-land planet with an atmosphere similar to modern Earth, there... [+] would be a ring of potential habitability with Earth-like temperatures and atmospheric pressures near the border between the eternal day/night sides, where the winds always flow from the night side to the day side.

    4:59 PM: This is also an important point: what's happening on a world around a red dwarf star isn't so much about the irradiance from the star and day/night temperatures and the border between them, but how the atmosphere circulates and what it's composed of.

    We also have to be very careful in distinguishing between "biosignatures," which is going to be a slam-dunk signal that tells us, "wow, that's a living planet right there," and a "bio-hint," which is what Bryan's referring to, which is pretty much guaranteed to get you false positives, over and over, before you actually get it right.

    This diagram shows the novel 5-mirror optical system of ESO's Extremely Large Telescope (ELT).... [+] Before reaching the science instruments the light is first reflected from the telescope's giant concave 39-metre segmented primary mirror (M1), it then bounces off two further 4-metre-class mirrors, one convex (M2) and one concave (M3). The final two mirrors (M4 and M5) form a built-in adaptive optics system to allow extremely sharp images to be formed at the final focal plane. This telescope will have more light-gathering power and better angular resolution, down to 0.005

    5:01 PM: This is really true: the ELT will be humanity's best chance, in the 2020s, for directly imaging an Earth-like (or potentially inhabited) planet of any type. This could lead us to a revolution, where bio-hints and bio-signatures could be abundant. Right now, planet-finders like TESS are giving us the best candidate planets for direct imaging, and while we'll have to get lucky, this is the high-reward science most of us dream about!

    In this artist's rendition, NASA's Clipper spacecraft makes one of its many dozen close passes to... [+] Europa, the most likely candidate for life in the Jovian system to date. With all the ingredients it possesses and the conditions as we know them on this world, Europa might be the most life-friendly world beyond Earth presently known to humanity. However, in order to know whether there's life in Europa's sub-surface ocean, we'll have to probe down beneath its enormously thick crust that's some 15+ kilometers thick.

    5:04 PM: Of course, this is the third possibility I haven't discussed for finding life: it could be right here in our Solar System! Do we have life in a subsurface ocean on Europa or Enceladus? Do we have subterranean, potentially seasonally active/inactive life on Mars? Do the outer worlds, like Triton or Pluto, have anything on them of interest?

    We have missions going to look, and hopefully in the 2020s, we'll start to get answers that teach us whether our fantastical interpretations of signals like seasonal methane or organic molecules really hold up. They could be biotic in nature, and we won't know until we do the appropriate tests!

    A small section of the Karl Jansky Very Large Array, one of the world's largest and most powerful... [+] arrays of radio telescopes. The radio capabilities of this array, in terms of resolution and sensitivity, place it among the top 2 or 3 arrays in the entire world.

    5:06 PM: This is a fun fact: you must not use a walkie talkie around radio telescopes; the interference is atrocious! Remember that people didn't know what "fast radio bursts" were for much longer than we realized, because the microwave oven in the break room of a giant radio telescope was causing interference? That's a true story; don't use walkie talkies near radio telescopes!

    5:07 PM: So I think this 1 hour talk has taught me how you talk about two topics when you spend the first 50 minutes on the first topic: just keep talking over your talk's time!

    5:10 PM: The present and the near future are incredibly exciting, and you don't need warp drive or actual aliens to make it so. But, that said, it would be pretty cool to achieve interstellar travel or to find any true signatures (not just hints + wishful thinking) of alien life.

    This is why we do science and why we develop technology; these are our sci-fi dreams and we're making them come true!

    5:12 PM: Alright, talk's over and we're into the Q&A. Hey, and the first question is "how do we go from that light of an exoplanet transiting" to "how do we extract all that useful information?" And the two answers are:

    1. transit spectroscopy, and
    2. direct imaging.

    Bryan is only giving the first answer, but both matter!

    5:14 PM: No to aliens in Roswell, New Mexico. Good answer, Bryan. I like the snark of, "why come all this way just to dissect a cow?"

    Alright, everyone, that's all the time I've budgeted for today's talk; hope you enjoyed the live blog and Bryan's talk! We might not have found aliens yet and we might still be quite far from reaching another star, but our technology has brought us quite an impressive way already, and we're headed towards something even more spectacular as the 2020s begin to unfold. Stay curious and please join me in looking forward to all the wondrous discoveries that this decade is sure to hold!

    Will Humanity Achieve Interstellar Travel And Find Alien Life? - PART I

    Although our dreams of making contact with an alien civilization have traditionally been rooted in... [+] either a direct visitation or the picking up of an intelligent signal transmitted throughout the galaxy, these remain long-shot possibilities. But real technology may enable us to find worlds where life is abundant and ubiquitous far sooner than we might have expected based on playing this cosmic lottery.

    For as long as human beings have looked up at the stars in the sky, two questions have captured our collective imaginations: are there other life forms out there on any of their worlds, and will we ever realize the dream of traveling to one of them? Although both tasks appear to have enormously daunting technical challenges, recent advances in science suggest that not only might humanity be capable of overcoming them, but we might even do so later this century.

    While faster-than-light travel and visitations from aliens ⁠— whether benign or malevolent ⁠— are staples of our science-fiction stories, it's plausible that our real-life scientific advances may legitimately be more profound than any fictional stories humans have dreamed up. On the edge of both frontiers, humanity may be on the cusp of achieving a dream as old as humanity itself.

    A logarithmic chart of distances, showing the Voyager spacecraft, our Solar System and our nearest... [+] star, for comparison. If we ever hope to travel across the great interstellar distances, it will require a technology that's superior to chemical-based rockets.
    The biggest problem with the idea of interstellar travel is scale. The distances to even the nearest stars are measured in light-years, with Proxima Centauri being our nearest neighbor at 4.24 light-years away, where one light-year is approximately 9 trillion kilometers: some 60,000 times the Earth-Sun distance. At the speed of the fastest space probes humanity has ever sent on their way out of the Solar System (the Voyager 1 and 2 spacecraft), covering the distance to the nearest star would take approximately 80,000 years.

    But all of this is based on current technology, which uses chemical-based rocket fuel for propulsion. The biggest downside of rocket fuel is its inefficiency: one kilogram of fuel is capable of generating just milligrams' worth of energy, as measured by Einstein's E = mc2. Having to carry that fuel on board with you ⁠— and requiring that you accelerate both your payload and the remaining fuel with that energy ⁠— is what's hamstringing us right now.
    Position and trajectory of Voyager 1 and the positions of the planets on 14 February 1990, the day... [+] when Pale Blue Dot and Family Portrait were taken. Note that it is only Voyager 1's position out of the plane of the Solar System that enabled the unique views we retrieved, and that Voyager remains the farthest object ever launched by humanity, but still has thousands of times farther to go until it travels ~4 light-years.

    But there are two independent possibilities that don't require us to dream up Warp Drive-like technologies that would rely on new physics. Instead, we can pursue the routes of either using a more efficient fuel to power our journey, which could increase our range and speeds tremendously, or we can explore technologies where the thrust-providing source is independent of the payload that's going to be accelerated.

    In terms of efficiency, there are three technologies that could vastly outperform chemical-based rocket fuel:

    1. nuclear fission,
    2. nuclear fusion,
    3. and matter-antimatter propulsion.

    Whereas chemical-based fuels convert a mere 0.0001% of their mass into energy that can be used for thrust, all of these ideas are far more efficient.

    All rockets ever envisioned require some type of fuel. Whether a plasma engine, a matter/antimatter... [+] engine, nuclear-powered or conventionally powered, rockets all work on the same principle of thrust, but the efficiencies can vary enormously.

    Fission converts approximately 0.1% of the mass of fissile materials into energy; approximately one kilogram of fissionable fuel yields about one gram's worth of energy, via E = mc2. Nuclear fusion does a superior job; fusing hydrogen into helium, for example, is 0.7% efficient: one kilogram of fuel would yield 7 grams' worth of usable energy. But far-and-away the most efficient solution is matter-antimatter annihilation.

    If we could create and control 0.5 kilograms of antimatter, we could annihilate it at will with 0.5 kilograms of normal matter, creating a 100% efficient reaction that produced a full kilogram's worth of energy. We could conceivably extract thousands or even a million times as much energy from the same amount of fuel, which could propel us to the stars on timescales of centuries (with fission) or even just decades (with fusion or antimatter).

    An artist's rendition of a laser-driven sail shows how a large-area, light-weight spacecraft could... [+] be accelerated to very high speeds by continuously reflecting back laser light that was high-powered and highly collimated. This could pose the most likely way that human beings have in their near-future arsenal of launching a macroscopic spacecraft over interstellar distances.

    On the other hand, we could work to achieve interstellar travel via a completely different route: by placing a large power source capable of accelerating a spacecraft in space. Recent advances in laser technology have led many to suggest that an enormous, sufficiently collimated array of lasers in space could be used to accelerate a spacecraft from low-Earth orbit to tremendous speeds. A highly reflective laser-sail, like a solar sail except specifically designed for lasers, could do the job.

    If a large-enough, powerful-enough array of in-phase lasers were constructed, potentially reaching gigawatt power levels, it could not only impart momentum to a target spacecraft, but could do so for a long period of time. Based on calculations performed by Dr. Phil Lubin a few years ago, it's possible that speeds up to 20% the speed of light could be reached. While we don't yet have a plan for decelerating such a spacecraft, reaching the nearest star in a single human lifetime is within the realm of possibility.

    The laser sail concept, for a starchip-style starship, does have the potential to accelerate a... [+] spacecraft to about 20% the speed of light and reach another star within a human lifetime. It's possible that, with enough power, we could even send a crew-carrying spacecraft to span the interstellar distances.

    By the same token, the search for extraterrestrial life is no longer restricted to either waiting for an alien visit or searching the Universe with radio signals for intelligent aliens, although the latter is certainly still an active scientific field spearheaded by SETI. Although no signals have been found, this remains a stunning example of high-risk, high-reward science. If a positive detection is ever made, it will be a civilization-transforming event.

    However, as exoplanet astronomy continues to advance, two techniques that have already been demonstrated could bring us our first signatures of life on other worlds: transit spectroscopy and direct imaging. Both of these involve using the light from a planet itself, with transit spectroscopy leveraging the light that filters through a planet's atmosphere and direct imaging taking advantage of the sunlight directly reflected off of the planet itself.

    When a planet transits in front of its parent star, some of the light is not only blocked, but if an... [+] atmosphere is present, filters through it, creating absorption or emission lines that a sophisticated-enough observatory could detect. If there are organic molecules or large amounts of molecular oxygen, we might be able to find that, too. at some point in the future. It's important that we consider not only the signatures of life we know of, but of possible life that we don't find here on Earth.

    Transit spectroscopy relies on us having a serendipitous alignment of our observatory with both a target exoplanet and its parent star, but these alignments do occur. Whereas a small fraction of the star's light will get blocked by the transiting planet, an even smaller fraction of starlight will transmit through the planet's atmosphere, similar to the sunlight that gets transmitted through Earth's atmosphere and lights up the Moon (in red) during a total lunar eclipse.

    This enables us, if our measurements are good enough, to decode what elements and molecules are present in the target planet's atmosphere. If we could discover biological signatures or even technosignatures  which could be an oxygen-nitrogen atmosphere, complex biomolecules, or even something like a chlorofluorocarbon (CFC) molecule  we would immediately have a strong hint of a living world that would tantalizingly await confirmation.

    Left, an image of Earth from the DSCOVR-EPIC camera. Right, the same image degraded to a resolution... [+] of 3 x 3 pixels, similar to what researchers will see in future exoplanet observations.

    Direct imaging could provide exactly that sort of confirmation. Although our first image of an Earth-sized exoplanet likely won't be very visually impressive, it will contain a ton of information that can be used to reveal indicators of life. Even if the planet itself is just one pixel in a detector, we could not only break its light apart into individual wavelengths, but can look for time-varying signatures that could reveal:

    • clouds,
    • continents,
    • oceans,
    • plant life greening with the seasons,
    • icecaps,
    • rotation rates,

    and much more. If there are light-emitting signatures at night, just as planet Earth has our light that illuminate the world at night, we could conceivably even detect those as well. If there's a civilization out there on a nearby Earth-like planet, the next generation of telescopes might be able to find them.

    The Earth at night emits electromagnetic signals, but it would take a telescope of incredible... [+] resolution to create an image like this from light years away. Humans have become an intelligent, technologically advanced species here on Earth, but even if this signal were smeared out, it might still be detectable by next-generation direct imaging.

    All of this, together, points to a picture where a spacecraft or even a crewed journey to the stars is technologically within our reach, and where the discovery of our first world beyond the solar system with possible life on it could occur in a decade or two. What was once solely in the realm of science-fiction is quickly becoming possible due to both technical and scientific advances and the thousands of scientists and engineers who work to apply these new technologies in practical ways.

    On February 5 at 7 PM ET (4 PM PT), Dr. Bryan Gaensler, director of the Dunlap Institute for Astronomy and Astrophysics at the University of Toronto, will be delivering a public lecture at Perimeter Institute on exactly this topic. Titled Warp Drive and Aliens: The Scientific Perspective, it's available to watch from anywhere on Earth, and I'll be following along with a live-blog in real time, below.

    How close is humanity to achieving this dream that's spanned innumerable generations? The answer is closer than you might think, so tune in here and follow along below (updates every 3-5 minutes) to find out what lies just beyond the known frontier. It could be the revolution we've all been hoping for!
    An illustration of the warp field from Star Trek, which shortens the space in front of it while... [+] lengthening the space behind it. The Spore Drive, both in Star Trek and the idea of traversing through an extra spatial dimension in our reality, could take us from point A to point B even more quickly.

     Okay, warp drive fans, here we go! The first thing you might be wondering is about whether warp drive itself is really feasible or not. And the answer, believe it or not, is maybe, but not unless we figure out a source of energy that goes well beyond anything we've got so far, including antimatter.

    The reason is simple: to achieve warp drive, you need to bend the space in front of you so that it contracts, and that can only occur at the expense of expanding the space behind you. This takes an enormous amount of energy all localized in one spot, and you need to do it while still keeping the space where your spaceship will be not too severely bent, or you'll wind up destroying it with terrific gravitational tidal forces.

    The Alcubierre solution to General Relativity, enabling motion similar to warp drive. This solution... [+] requires negative gravitational mass, which could be exactly what antimatter might provide.

    But if you can do it, and it is something allowed in General Relativity, this requires not only the matter-and-energy we know, but also some form of negative energy: either matter with negative mass or a form of anti-energy itself. If we could harness this, it would mean we could travel through the contracted space (slower than light), but we could do something like contract a 40 light-year journey down to 6 light-months.

    Even if we only traveled through that now-contracted space at half the speed of light, we'd get there in 1 year, rather than 40. That's pretty impressive!

    The warp drive system on the Star Trek starships was what made travel from star to star possible. If... [+] we had this technology, we could easily bridge the distance to the stars, but this remains in the realm of science fiction for today. Star Trek Discovery's Spore Drive opens up a new possible mechanism for faster-than-light travel that may be even superior to Warp Drive.

    That doesn't mean, however, that the plot devices or treknobabble cooked up by Star Trek's writers, which includes things like:

    • dilithium crystals,
    • warp nacelles,
    • Bussard ramjets
    • warp cores,

    or anything else we might immediately refer to has any relevance. Science fiction provides us with possible outcomes, but only very rarely gets the path to that technological solution correct. We know enough about physics, today, to be certain that Star Trek's "solution" to this problem is not feasible. But, then again, that's part of what makes science so wonderful: it can take a fictional idea and make it a reality. Or, if we're really lucky, surpass our sci-fi dreams!

    US Navy Submarine ‘Encountered 500mph UFO in Ocean’ 4 Years After Nimitz’ Sighting

    Article By Simon Green - (dailystar.co.uk)

    • Mike Turber, who claims to be a former Air Force intelligence expert, revealed on

    ‘The Hidden Truth Show’ with Jim Breslo (see videos below) that the infamous ‘Tic

    Tac’ UFO captured on video by Navy pilots with the USS Nimitz carrier group off of

    San Diego in 2004 is actually technology created by the US military. However, the

    Navy says that it is not able to identify the object, calling it a ‘UAP’ or ‘unidentified

    aerial phenomena’.

    • Ever since the revelation in 2017 of the Nimitz’ UFO encounter, there has been an

    overwhelming sense that there is more footage yet to be disclosed. In January, a US

    Navy spokesperson confirmed that a longer video classified “secret” does exist.

    Turber says that this footage would be at least 10 minutes long and is far clearer

    than the first one. Turber noted that the FLIR video recorder is turned on when the

    jet launches, so the entire beginning of the video seems to be missing.

    • Turber claims that in 2007 or 2008, a craft matching the description of the ‘Tic Tac’

    UFO was spotted hurtling through the water at 550mph by a US Navy submarine. “I

    thought it was just a torpedo,” said Turber, “but, apparently not.” Turber told

    the Daily Star Online that this US military craft is capable of traveling at astonishing

    speeds both in the air and under the sea.

    A craft matching the description of the USS Nimitz UFO was spotted by a US Navy submarine hurtling at 550mph through the water in a previously unrevealed encounter, a former US Air Force intelligence expert has claimed.

                          

      

    Jim Breslo                        Mike Turbo  

    The sighting of a ‘tic-tac’ craft by two US Navy fighter jets in 2004 has become one of the most famous UFO videos of all time.

    The US Navy is still unable to explain the object, previously identifying it as an Unidentified Aerial Phenomena.

    But Mike Turber, an intelligence expert who claims to have worked in the USAF, claims the craft was actually created by the US military.

    He first made his bombshell comments on The Hidden Truth Show with Jim Breslo.

    And in an exclusive chat with Daily Star Online, he suggested the craft is capable of hurtling at astonishing speeds in both the air and sea.

    “There was a submarine situation – that report will probably come out further down the line,” he explained.

    “It (the tic-tac object) was travelling at 550mph. As far as I know, it was a Los Angeles-class submarine.

    Powerful Radio Signal From Deep Space Appears to Be Repeating in a 16-Day Cycle

    MICHELLE STARR

    One of the defining characteristics of the mysterious deep-space signals we call fast radio bursts is that they are unpredictable. They belch out across the cosmos without rhyme or reason, with no discernible pattern, making them incredibly hard to study.


    Now, for the first time, astronomers have found a fast radio burst (FRB) that repeats on a regular cycle.

    Every 16.35 days, the signal named FRB 180916.J0158+65 follows a similar pattern. For four days, it will spit out a burst or two every hour. Then it falls silent for 12 days. Then the whole thing repeats.

    Astronomers with the Canadian Hydrogen Intensity Mapping Experiment (CHIME) Collaboration in Canada observed this cycle for a total of 409 days. We don't yet know what it means; but it could be another piece in the complicated conundrum of FRBs. The research has been uploaded to pre-print server arXiv, where it awaits scrutiny from other experts in the field.

    It's easy to become somewhat obsessed with fast radio bursts, a fascinating space mystery that has so far defied any attempts at a comprehensive explanation.

    To recap, FRBs are hugely energetic flares of radiation in the radio spectrum that last just a few milliseconds at most. In that timeframe, they can discharge as much power as hundreds of millions of Suns.

    Most of them spark once, and we have never detected them again. This makes it rather difficult to track these bursts down to a source galaxy. Some FRBs spit out repeating radio flares, but wildly unpredictably. These are easier to track to a galaxy, but so far, that hasn't brought us a great deal closer to an explanation.

    Last year, the CHIME collaboration announced they had detected a whopping eight new repeating fast radio bursts, bringing the then-total of repeaters to 10 out of over 150 FRB sources. (Another paper recently brought that total up to 11.)

    FRB 180916.J0158+65 was among the eight repeaters included in last year's haul; apart from its repeat bursts, initially it didn't appear to be anything special. But as the CHIME experiment continued to stare at the sky, a pattern emerged.

    This is exciting, because it offers new information that can be used to try and model what could be causing FRB 180916.J0158+65.

    "The discovery of a 16.35-day periodicity in a repeating FRB source is an important clue to the nature of this object," the researchers wrote in their paper.

    Other objects that demonstrate periodicity tend to be binary systems - stars and black holes. The 16.35-day period could be the orbital period, with the FRB object only facing Earth during a certain part of the orbit.

    FRB 180916.J0158+65 is one of the handful of FRBs that have been traced back to a galaxy. It's on the outskirts of a spiral galaxy 500 million light-years away, in a star-forming region. This means a supermassive black hole is unlikely, but a stellar-mass black hole is possible.

    "The single constraint on the orbital period still allows several orders of magnitude range in companion mass amongst known stellar-mass compact object binaries: from so-called 'black widow' binary systems, consisting of a low-mass star and a powerful millisecond pulsar whose wind ablates the companion (albeit typically with few-hour orbital periods), to massive O/B stars with highly eccentric companion pulsar orbits," the researchers wrote.

    Alternatively, winds from the companion object, or tidal disruptions from a black hole, may periodically somehow block the FRB radiation.

    It also can't be ruled out that the FRB source is a single, lone object such as a magnetar or X-ray pulsar, although the researchers note this explanation is a little harder to reconcile with the data. That's because those objects have a wobbling rotation that produces periodicity, and none are known to wobble that slowly.

    And radio pulsars that do have periodic intervals of several days are orders of magnitude fainter than FRBs. So it's still a mystery.

    But remember that 11th repeater we mentioned earlier? It was found coming from an FRB astronomers had thought was a one-off; its repeats were simply too faint for the equipment that had initially been used to look for them.

    This suggests that many more FRBs could be repeating, but outside our detection range. And the fact that FRB 180916.J0158+65 seemed more or less the same as other FRBs could mean that other repeating FRBs are also on a cycle - we just haven't detected those cycles yet.

    So, the next step would be, of course, to continue staring at FRB 180916.J0158+65 for a bit. But it also would be pretty interesting to try and see if periodicity can be detected in other bursts as well.

    "Future observations, both intensity and polarimetric, and at all wavebands, could distinguish among models and are strongly encouraged," the researchers wrote, "as are searches for periodicities in other repeaters, to see if the phenomenon is generic."

    The research is available on arXiv ahead of peer review.

    NASA Scientists: A Lot More Dangerous Comets Exist Than We Thought

    The Trump administration released a report Thursday outlining the steps NASA and other agencies were taking to prevent state-sized asteroids from pulverizing planet Earth. (Shutterstock/muratart)

    ENERGY AND SCIENCE REPORTER

    NASA scientists say a new study proves there are seven times as many big and potentially dangerous comets flying through deep space than previously thought.

    The study analyzed data from the Wide-field Infrared Survey Explorer (WISE) spacecraft that tracks “long-period” comets (LPCs) that take at least 200 years to orbit around the sun. WISE data showed far more LPCs that potentially pose a serious impact risk to Earth.

    “Previously the sense was that for every 100 asteroid impacts (of all sizes) we get 1 comet impact,” Dr. Joseph A. Nuth, a senior asteroid scientist at NASA’s Goddard Space Flight Center, told The Daily Caller News Foundation. “Now that we know there are more LPCs for every 100 asteroid impacts we might get 5 comet impacts.”

    Astronomers previously gave broad estimates of the number of LPCs in the solar system, but researchers didn’t have a good way to detect them since they were obscured by clouds of gas and dust.

    Gravitational forces can move LPCs back into the inner solar system, potentially putting them on a collision course with Earth. An LPC impact would be devastating.

    “A comet impact is, on average, much more devastating than an asteroid impact, Nuth said. “Think BBs and Bullets vs. Howitzers and Nukes.”

    Comets are rarer than asteroids, but can carry more than 100 times the energy of a typical asteroid. An LPC would likely impact Earth at a much higher velocity than other space objects.

    “[A] higher velocity impact would release more energy and therefore would be worse,” Paul Chodas, manager of the Center for Near-Earth Object Studies at NASA’s Jet Propulsion Laboratory, told TheDCNF. “This is offset somewhat by the fact that comets are less dense than asteroids: the energy release of a comet impact would be less than that of a similarly sized asteroid impact if the velocities were the same.”

    The study also determined that LPCs are more dangerous than more conventional asteroids or comets because they are twice the size on average.

    “Yes, a body twice the size has eight times the mass of a smaller body and therefore delivers eight times the kinetic energy if all other factors are equal,” Nuth said. “The impact energy is proportional to the velocity squared.  So a comet moving three times the average asteroid velocity would impact with nine times the energy.”

    “The potential impact of a long-period comet would be more hazardous than that of a Jupiter family comet both because the long-period comets are more likely to be larger, and because they follow orbits that would impact at higher velocities,” Chodas said.

    The final reason researchers think LPCs are dangerous is their relative stealthiness compared to other space rocks. Detecting an LPC on a collusion course with Earth would be more difficult that spotting a more conventional near-Earth asteroid.

    “The larger distance of comets, and the long orbital periods affect the warning time more than higher velocities: the generally larger distance of comets make the tracking observations less effective (since they are angular measurements), and the longer orbital periods mean that we don’t have multiple opportunities to see these objects at closer ranges,” Chodas said. “The distance at which a comet is discovered depends largely on the activity level of the comet.”

    The difficulties inherent in detecting LPCs mean that NASA would likely have far less warning that one was on a collision course with Earth. The comet Siding Spring was detected on a trajectory that would strike the planet Mars in October of 2014, just 22 months after its discovery.

    “Since Comet Siding Spring was quite active, it was discovered at a distance of 7 AU, about two years before it passed very close to Mars,” Chodas said. “A less active long-period comet might be discovered only a year before entering the inner Solar System. Establishing a precise trajectory for the comet would be challenging and likely take several months, so the warning time would likely be less than a year.”

    Twenty-two months warning is far less than NASA scientists think they’d need to intercept an incoming comet. The best way to stop an asteroid or comet from hitting the Earth on such short notice may be to send a spacecraft up to intercept it. But even then, NASA researchers think they would need at least five years to construct a reliable spacecraft and man it.

    “The case of Siding Spring is a reasonable example: much less than 5 years is a good guess,” Nuth said.  “Siding Spring came in from the celestial pole and was not spotted until it began to exhibit a coma. A larger body would show a coma at similar distances.”

    Earth is just as vulnerable to LPCs and other space rocks as Mars nearly was to the Siding Spring Comet. Earths’ closer proximity to the Sun wouldn’t make it easier to detect a long-period comet on a collision course, according to NASA researchers.

    “The discovery time is dictated mostly by the comet’s distance from the Sun and how active the comet is,” Chodas said. “If Comet Siding Spring were headed for an encounter with Earth, its discovery time would be the same.”

    Exclusive: Strange Russian Spacecraft Shadowing U.S. Spy Satellite, General Says

    Apair of Russian satellites are tailing a multibillion-dollar U.S. spy satellite hundreds of miles above the Earth’s surface, a top U.S. military commander tells TIME, underscoring a growing threat to America’s dominance in space-based espionage and a potentially costly new chapter in Washington’s decades-long competition with Moscow.

    Gen. John “Jay” Raymond, commander of the newly minted U.S. Space Force, says the Russian spacecraft began maneuvering toward the American satellite shortly after being launched into orbit in November, at times creeping within 100 miles of it. “We view this behavior as unusual and disturbing,” Raymond says. “It has the potential to create a dangerous situation in space.” Raymond says the U.S. government has expressed concern to Moscow through diplomatic channels.

    The confrontation marks the first time the U.S. military has publicly identified a direct threat to a specific American satellite by an adversary. The incident parallels Russia’s terrestrial encounters with the U.S. and its allies, including close calls between soldiers, fighter jets and warships around the world. Observers worry that space is now offering a new theater for unintentional escalation of hostilities between the long-time adversaries.

    Pentagon, White House and Congressional backers, say the incident demonstrates the need for the Space Force, which President Donald Trump established in December when he signed the National Defense Authorization Act into law. It became the first new military service since the Air Force was created in 1947.

    The Space Force, for which the White House is requesting $15 billion in this week’s budget proposal, represents a strategic shift from passively operating and observing satellites to actively defending them. Space warfare doctrine remains a work in progress, but Raymond has spoken about the need to mobilize Space Command against perceived threats because other nations, especially Russia and China, have become increasingly sophisticated at building arsenals of lasers, anti-satellite weapons and state-of-the-art spacecraft designed to render the U.S. deaf, mute and blind in space.

    At the same time, the expansion of military operations in space harks back to another hallmark of the Cold War competition between Washington and Moscow: massive spending on perceived threats, regardless of the cost.
    For those monitoring waste, fraud and abuse in the military industrial complex, the Russian maneuver and the Pentagon’s response also portends a new front in the effort to keep real and potential threats from becoming a budgetary sinkhole. The history of U.S.-Russia military competition is full of examples of perceived threats that require costly responses.

    “The initial costs of setting up the Space Force are likely a small down payment on an undertaking that could cost tens of billions of dollars in the years to come,” says William D. Hartung, director of the arms and security project at the Center for International Policy. “The last thing we need is more bureaucracy at the Pentagon, but that’s exactly what the Space Force is likely to give us. Creating a separate branch of the armed forces for space also risks militarizing U.S. space policy and promoting ill-advised and dangerous projects that could involve deploying weapons in space.”

    The Russian embassy did not respond to requests for comment about the allegedly threatening maneuvers by its satellites. The Kremlin has previously stated they are not weapons, but rather “inspector” spacecraft engaged in an “experiment.”

    U.S. military analysts first noticed something peculiar after Russia launched its spacecraft into orbit November 26 from Plesetsk Cosmodrome aboard a Soyuz rocket. The Russian satellite had been in orbit less than two weeks when, bafflingly, it split in two. As the analysts looked closer, they suspected that a second smaller satellite was somehow “birthed” from the first one. “The way I picture it, in my mind, is like Russian nesting dolls,” Raymond says. “The second satellite came out of the first satellite.”

    The maneuver was later confirmed on Dec. 6 when the TASS news agency cited Russia’s Defense Ministry saying the two had separated. “The purpose of the experiment is to continue work on assessing the technical condition of domestic satellites,” the statement said.

    However, the satellites, identified as Cosmos 2542 and Cosmos 2543, appeared to be carrying out another mission. By mid-January, they were sidling near the American satellite, identified as USA 245, known to space experts as a KH-11.

    The U.S. satellite, part of a reconnaissance constellation codenamed Keyhole/CRYSTAL, is operated by the National Reconnaissance Office (NRO), the secretive intelligence agency headquartered in Chantilly Va. Although the NRO refuses to comment on the large school bus-sized satellites, the KH-11’s capabilities are often compared by experts in the field to the Hubble Space Telescope. Instead of staring into the vast expanse of space, however, the satellites’ sensors and cameras are focused into the heart of foreign adversaries’ top-secret military installations

    A KH-11 satellite, known as USA 224, is widely believed by analysts to have taken the image of Iran’s Imam Khomeini Space Center that President Donald Trump posted to Twitter in August. The photo was so detailed, you could make out the Farsi characters written along the edge of the launchpad. The KH-11 constellation, which consists of four satellites that maintain constant Earth observation, operate in a polar orbit above the rotating Earth, enabling them to cover its entire surface.

    Russia’s curious space activities were first noted on Twitter last week by Michael Thompson, an amateur satellite tracker, who used publicly available data to speculate on what it was up to. “The relative orbit is actually pretty cleverly designed, where Cosmos 2542 can observe one side of the KH11 when both satellites first come into sunlight, and by the time they enter eclipse, it has migrated to the other side,” Thompson wrote in a series of tweets. “This is all circumstantial evidence, but there are a hell of a lot of circumstances that make it look like a known Russian inspection satellite is currently inspecting a known US spy satellite.”

    Raymond says he’s concerned because Russia is demonstrating capabilities the U.S. first saw three years ago, when Moscow tested the “Russian nesting doll” technology. “In 2017, they launched a satellite, it launched another satellite,” he says. “The satellites exhibited characteristics of a weapon system when one of those satellites launched a high-speed projectile into space.”

    While Raymond’s allegation couldn’t be verified, the U.S. did raise the issue in 2018, warning about Russia’s “very troubling” behavior at the U.N.’s Conference on Disarmament that year without providing specifics.

    Moscow’s intent with the current mission remains unknown, but the Russian spacecraft should be capable of capturing high-resolution imagery of the American satellite as it conducts its mission, spying deep into adversaries’ territory. It’s akin to handing over a state-of-the art spy satellite to Russian scientists for forensic analysis.

    Brian Weeden, a former Air Force officer and expert in space security at the Secure World Foundation, says the Russian satellites’ positioning could allow it to determine things like where the KH-11 is “pointing—and thus what ground targets its taking picture of—as well as the general operating schedule and usage.”

    Further, if the Russian satellites are outfitted with electronic emissions probes, they could listen for radio frequency signals to try figure out how the KH-11 communicates and even attempt to intercept those communications, which are likely encrypted, says Todd Harrison, director of the Aerospace Security Project at the Center for Strategic and International Studies. “There are a lot of things it could be doing,” Harrison says. “They could simply be practicing on-orbit maneuvers or signaling to the United States that they have this capability.”

    The Keyhole program is 44 years old and the satellites are widely known to have similar capabilities as the Hubble Telescope. The U.S., China and other nations have already shown the ability to launch spacecraft into close orbit with their own satellites. The Kremlin could be showing the U.S.—in a very obvious way—that it has joined the club.

    From Raymond’s standpoint, however, maneuvering close to a foreign satellite for an “inspection” is virtually indistinguishable from staging an attack to damage, disrupt or destroy it. “It’s clear that Russia is developing on-orbit capabilities that seek to exploit our reliance on space-based systems that fuel our American way of life,” he says. Raymond wouldn’t comment specifically on Russia’s intentions with the shadowing satellites

    Over the past decade, space weaponry has gone from the stuff of science fiction to reality. A flurry of advancements from the U.S., Russia and China has altered the image of outer space as a peaceful sanctuary and instead stoked fears that an arms race has extended into the heavens.

    But even if the Russian satellites are doing the most intrusive things the Pentagon and outside observers imagine, none of them would violate treaties or international law. Absent binding agreements, the incident portends a growing a cat-and-mouse game in space. “We prefer space to remain free of conflict,” Raymond says. “We think that responsible space-faring nations need to have conversations about developing these norms going forward.”

    It is a historical truth that where humans have ventured, violence has followed. But conflict in space isn’t in any nation’s interest. There are more than 1,000 American satellites circling the planet, enabling everything from commerce, banking, transportation and communications. Russia, China and other developed nations have also grown increasingly dependent on satellites for commercial as well as military purposes, which raise the risks for miscalculation.

    The U.S. government’s space-based operations are among the most highly technical and classified secrets in its possession. Raymond’s willingness to go on the record about the ongoing event provides a glimpse into what military officials see as an increasingly congested and contested environment.

    Robert Cardillo, the former director of the U.S. National Geospatial-Intelligence Agency, says space is a “messy environment,” which without established rules, could turn into the Wild West. An attack on a satellite constellation, such as GPS, which is owned and operated by the U.S. Air Force, could have far-reaching consequences like halting ATM banking transactions or causing a blackout in navigation applications on users’ smartphones, which occurs billions of times a day around the globe.

    The developments hark back to military concept that helped keep the world safe from nuclear apocalypse during the Cold War. Mutual assured destruction (MAD)—the military doctrine that posited a nuclear strike from one nation would result in a full-scale counterattack from the other—helped prevent the U.S. and the Soviet Union from using the massive arsenals they each amassed during decades of armed standoff.

    But MAD eventually became backstopped by a series of treaties and open lines of communication designed to avoid accidental escalation of conflict. The U.S., Russia and other nations have yet to establish a similar diplomatic structure for space, and experts warn of the dangers of weaponizing the cosmos without them. “Deterrence is something we just haven’t dealt with,” in space Cardillo says. “If you make it, you can break it.”

    Date of sighting: Feb 10, 2020
    Location of discovery: Earths Sun, 45-45 degree 
    Source software: 

    I found this black triangle UFO on our sun a few months ago and I am still watching it. I can see it daily using this special software designed by the ESA (european space admistration). Anyone can download it and use it. This shows me that the triangle UFO is still there. Its black, so we know its surface is heat resistant or has some kind of protective electronic shield around it. 

    Its unbelievable that NASA has never even mentioned this triangle craft, but I guess they think the public would panic if they knew. Because admitting its a craft would mean admitting that intelligent aliens exist.

    Hey, Google, Where Are the Aliens? How UFO Enthusiasts Utilize Tech Giant’s Services to Search ETS in Antarctica

    ufo-Antarctica

    In December last year, UFO fans were engaged in debates over a large mysterious hole in Antarctica. Users believed the humongous structure was an entrance to a secret military facility, which first appeared in 2007. However, it vanished shortly afterwards. Twelve years later, it was found again on Google Maps.

    It appears that Antarctica has long pulled in fans of conspiracy theories since wild stories surfaced that high-ranking Nazi officers could have escaped and gone to Antarctica. However, Antarctica has become the most famous place for hunting aliens using Google’s services. Here are the most exciting finds.

    The Alien Face

    One may believe that aliens want humanity to find them after seeing the alien image. A huge alien-like face on snow was discovered in Antarctica via Google Earth. Footage posted on Instagram by ufo_scandinavia quickly made the rounds on the internet with some social media users claiming the structure was left by aliens or an ancient civilisation that lived in Antarctica.

    Alien Ship

    UFO fans got baffled after YouTube user MrBB333 shared what he claims is a possible capsized ship in Antarctica. On his channel, he posted a man showing how he found a long cylindrical shape in the ground via Google Earth.

    Strange Disc-Shaped Object on Mountain

    It is another find that baffled conspiracy theorists. YouTube user Sandra Elena Andrade posted a video in December 2019 showing a massive black object that many commenters said was an alien ship. The woman discovered the mysterious object through Google Earth.

    Ancient Alien City

    YouTube channel thirdphaseofmoon co-author Blake Cousins claimed to have found an entrance to a hidden base, thought to be owned by aliens. He said that the dark shape on the snow looks like each one has a tunnel or cave that possibly connected underneath the show. Some social media users believed Blake’s version, while others thought this could be a hiding spot for a government project or Nazis.

    Massive Hole

    The YouTube channel thirdphaseofmoon stunned UFO followers again when they found a mysterious hole on Google Maps in December 2019. The humungous hole first appeared in 2007 but disappeared shortly afterward. According to Brett and Blake Cousins, this cave could potentially accommodate up to thousands of people. Brett added that it is big enough for flying saucers and spacecraft or even assets in our military to fly.

    Study examines effects of nuclear war on Earth’s oceans

    Researchers concluded that even a contained nuclear conflict would take a toll on Earth’s oceans and potentially disrupt the human food web. “The impacts are huge,” a scientist said.

    You’ve likely heard of nuclear winter, a hypothesis explored by decades of scientific research. It’s the idea that – following the firestorms produced in an all-out nuclear war – the soot lifted into Earth’s stratosphere would cause serious cooling, and subsequent crop failures and famines. Now a new study has looked at how even a relatively contained nuclear conflict – for example, a hypothetical war between India and Pakistan – might shift the chemistry of Earth’s oceans. The reasoning is reminiscent of that behind nuclear winter: soot lifted into the atmosphere would cause cooling. In the new study, the researchers concluded that even a contained conflict would “take a toll” on the oceans and potentially disrupt the human food web.

    Nicole Lovenduski of University of Colorado Boulder (CU Boulder) led the study. She commented in a statement:

    The impacts are huge.

    The journal Geophysical Research Letters published the new study in late January 2020.

    These researchers used global climate models to conduct their simulations. They looked at four possible nuclear conflicts, including three in India/Pakistan of differing magnitudes (5 teragrams, 27 teragrams, and 47 teragrams of soot produced, respectively; a teragram is equal to one trillion grams or 1,000 kilotons), and one all-out U.S./Russia case with 150 teragrams of soot produced. Writing at LaboratoryEquipment.com, Michelle Taylor penned a succinct explanation of what would happen in even the “tamest” of the India-Pakistan simulations. She wrote:

    … the researchers found that the conflict would likely generate huge amounts of black carbon high in Earth’s atmosphere, causing the globe to cool. Interestingly, the researchers found that the fallout from a nuclear detonation would come in two stages: the first within one year, and the second between three and five years post-bombing.

    Soon after denotation and no longer than one year later, global climate models showed the acidity of the world’s oceans would likely dip. Years later, the world’s salt water would begin to suck up more carbon dioxide from the air. Supplies of carbonate in the oceans would shrink, removing the key ingredient that corals use to maintain their reefs and oysters use to sustain their shells.

    Lovenduski told Taylor that – beyond taking a toll on crustaceans – a major disruption of the oceanic food web would undoubtedly severely impact the human food chain. Taylor wrote:

    That’s because there are more than 3 billion people in the world today who depend on ocean fisheries for protein and/or income.

    Brian Toon, also of CU Boulder, was a co-author on the study. He commented in the team’s statement:

    This result is one that no one expected. In fact, few people have previously considered the impact of a nuclear conflict on the ocean.

    Lovenduski commented:

    A lot of things would change in the oceans once you dim the lights [via soot in the atmosphere]. The way the water moves in the ocean, for example, is sensitive to how much heat it gets from the atmosphere …

    It makes me question whether organisms could adapt to such a change. We’re already questioning whether they can adapt to the relatively slower process of man-made ocean acidification, and this would happen much more abruptly.

    Lovenduski said it’s too soon to say for sure what the fate of shelled creatures in the oceans would be if nuclear war broke out. She said she hopes that her group’s findings will bring more attention to the wide-ranging devastation that would follow even a limited nuclear exchange. There’s no such thing, she said, as a minor nuclear war, adding:

    I hope this study helps us to gain perspective on the fact that even a small-scale nuclear war could have global ramifications.

A new study shows that even a limited nuclear conflict could have damaging effects on Earth’s oceans. The bombs would not have to explode over the ocean for the effects to take place.
