In an interesting new study, researchers have revealed that several ancient volcanic eruptions actually helped the dinosaurs to dominate the planet and thrive for so many millions of years. The volcanic eruptions started happening about 230 million years ago which caused significant changes to the environment and ecology such as Earth’s carbon cycle as well as the climate.

Researchers came to this conclusion by studying sediment and fossil plant records that came from a lake in the Jiyuan Basin in the northern part of China. They noticed that there was more humidity and higher temperatures that were caused by extreme volcanism and climatic shifts. These environmental changes included the CPE’s (Late Triassic Carnian Pluvial Episode) “mega monsoon” climate around 234 to 232 million years ago. When these changes occurred, massive amounts of marine creatures were wiped out, conifer trees increased in numbers, and dinosaurs became dominant.

Jason Hilton, who is a professor of paleobotany and paleoenvironments at the University of Birmingham in Britain and a co-author of the study, went into further details, “Within the space of two million years the world’s animal and plant life underwent major changes including selective extinctions in the marine realm and diversification of plant and animal groups on land,” adding, “These events coincide with a remarkable interval of intense rainfall known as the Carnian Pluvial Episode.”

As a matter of fact, the researchers separated the shift that lasted two million years into four episodes that were each caused by a volcanic pulse. These events allowed more carbon to be released into our atmosphere which ended up making our planet warmer and caused large amounts of rain to fall.

Dr. Sarah Greene, who is a Senior Lecturer at the School of Geography, Earth and Environmental Sciences at the University of Birmingham as well as being another co-author of the study, weighed in by noting, “Our results show that large volcanic eruptions can occur in multiple, discrete pulses – demonstrating their powerful ability to alter the global carbon cycle, cause climate and hydrological disruption and drive evolutionary processes.”

While these climatic shifts gave rise to the dinosaurs, experts still aren’t clear as to the reasoning behind it as explained by Emma Dunne who is a paleobiologist at the University of Birmingham but was not involved in the study, “This relatively long period of volcanic activity and environmental change would have had considerable consequences for animals on land.” “At this time, the dinosaurs had just begun to diversify, and it’s likely that without this event, they would never have reached their ecological dominance we see over the next 150 million years.”

Well, at least the dinosaurs benefited from the numerous volcanic eruptions that took place millions of years ago – until the asteroid wiped them out 66 million years ago.

The study was published in the journal PNAS where it can be read in full.

For many recent nighttime observers in North America and Europe, strange glowing lights may have made an appearance in the evening skies.

Although they may have looked otherworldly in appearance, these phenomena were of the celestial variety, rather than indications of extraterrestrial visitation.

On Monday, a powerful geomagnetic storm was logged by the National Oceanic and Atmospheric Administration (NOAA), who predicted that resulting displays of the aurora borealis could have been visible as far south as New York, Wisconsin, and Washington.

Geomagnetic storms occur when Earth’s sun ejects energy in the form of highly charged particles that strike the magnetic field that encircles our planet. As the particles collide with our planet’s magnetic shielding, it creates the famous dancing auroral displays, which under the right conditions can be very colorful and vivid.

NOAA features an online aurora forecast that provides real-time updates on when and where auroral appearances will be visible to nighttime viewers in the northern hemisphere. Similarly, viewers further south may occasionally be able to spot the aurora australis, the southern counterpart to the aurora borealis, which can be seen from various locales in the southern hemisphere.

However, the aurora borealis probably wasn’t the only thing causing the appearances of eerie lights in the night sky over parts of North America this week.

Many skywatchers in North Carolina were also made privy to a light show in recent days as a mysterious object was seen streaking through the sky shortly after 7:30 PM. Was it a UFO?

Probably not in this case, according to the American Meteor Society (AMS), who received videos of the nighttime intruder from North Carolinians who managed to film it, and said the object was a bright fireball.

The AMS says it was one of a handful of similar fireball sightings that occurred across North America last Friday night.

The meteor apparently cut through the atmosphere at a height of around 48 miles as it entered above Jacksonville, North Carolina. Observers estimate that it traveled at speeds nearing 32,000 miles per hour as it burned along.

According to its outlook for the dates encompassing when the sighting occurred, the AMS said that the estimated total hourly meteor rate for observers had been near 2 for observers in northern latitudes, and 1 as seen from tropical southern locations.

“The actual rates will also depend on factors such as personal light and motion perception, local weather conditions, alertness, and experience in watching meteor activity,” the AMS outlook read, adding that “Rates are reduced due to moonlight during this period,” and that “observers viewing from urban areas will see less activity as only the brighter meteors will be visible from such locations.”

Like auroras, the dynamics of meteors are well understood, although there have been a variety of anomalous occurrences associated with each of these phenomena, namely involving unusual sounds associated with the passage of bright fireballs through the sky. These noises that often accompany meteors have long baffled astronomers, because they cannot easily be reconciled as being produced by the objects burning through the sky since observers often report them simultaneously, as opposed to several seconds (or even minutes) later, allowing time for such sounds to travel.

While some phenomena associated with meteors does obviously remain mysterious, recent sightings of unusual things in the night sky over the Northern Hemisphere do seem to have a reasonable explanation, this time.

Some of the Moon’s Craters are so Dark, it Takes AI to see What’s Inside Them

There is no dark side of the Moon.  But there are dark spots on it – specifically at the bottom of craters that are never reached by any sunlight no matter where the Moon is facing.  These areas have intrigued scientists for decades, in no small part because lack of sunlight means a lower temperature, allowing frozen materials to stay frozen. In other words, there may be water in them thar craters.  And water will be the lifeblood of any future permanent crewed lunar mission.  

Unfortunately, lack of sunlight also means it’s challenging to see what’s at the bottom of those craters.  The closest scientists have come was when LCROSS, a NASA moon mission, fired a projectile into the crater Cabeus and analyzed the resultant dust cloud, which contained a relatively high amount of water.  But so far, no one has been able to image what water is in those craters directly.

That is not to say the craters are illuminated at all.  Even when they are not in direct sunlight, reflected sunlight, some of which might have bounced off nearby hills, is still channeled into the crater. But any images captured using that reflected light are too “noisy” to make out any detailed features.  

Enter a new technique developed by scientists at the Max Planck Institute for Solar System Research (MPS) in Germany.  They used an AI algorithm called the Hyper-effective nOise Removal U-net Software (HORUS).  HORUS’s primary goal is to “clean up” the noisy images of the bottom of unlit craters collected by other spacecraft, such as the Lunar Reconnaissance Orbiter (LRO).  In addition to removing noise, the software must also correct for other factors, such as the movement of LRO itself.

Despite such difficulties, the researchers used 70,000 images from LRO to calibrate the software, which was then unleashed upon 17 different permanently dark regions at the lunar south pole.  The largest area studied was 54 sq km, while the smallest was a mere 0.18 sq km.

With the new software, the image of the bottom of the crater is improved significantly.  Unfortunately, the photos don’t show any direct evidence of water, such as bright patches that would indicate ice. However, any crewed mission that wants to look for water in or under the regolith of these craters will first need to know what terrain it is entering.  Defining such terrain is where HORUS shines – the researchers could make out geological features a few meters across, which could be potentially hazardous to a lander or rover.

This was the first step toward exploring these previously invisible parts of the Moon.  With luck, someday, humans will be able to explore these areas safely, and with even more luck, they might find a source of an essential ingredient of all Earth-bound life.

ANCIENT TABLET DISPLAYS PYTHAGOREAN THEOREM 1,000 YEARS BEFORE PYTHAGORAS WAS EVEN BORN

LIAM STEWART

An almost 4000-year-old clay tablet displays an early form of applied geometry practiced by the ancient Babylonians, thousands of years before the math was initially thought to have been discovered.

BACKGROUND: DID THE BABYLONIANS HAVE GEOMETRY?

Trigonometry was largely understood to have been first discovered by the Greeks around the second century BCE. The word itself came from a combination of the Greek words for ‘earth’ and ‘measure.’

Prominent figures such as Euclid and Pythagoras created foundations and theorems that were instrumental in advancing the understanding of mathematics throughout the western world. Some of their work is still being used in current modern applications, such as Pythagoras’ theorem regarding right triangles.

While the Greeks may have had the greatest impact worldwide with their mathematical discoveries, it would eventually be revealed that they were not the first. In 2017, researchers at the University of New South Wales found a famous Babylonian tablet from 3,700 years ago, known as “Plimpton 322,” that contained a trigonometric table inscribed on it. It had sequences of numbers that are known as Pythagorean triples, despite it being thousands of years before Pythagoras lived when the tablet was used.

ANALYSIS: THE ANCIENTS WERE MATH NERDS

Dr. Daniel Mansfield of the University of New South Wales, who was a part of the same team that discovered Plimpton 322 in 2017, revealed that a different clay tablet from the same time period in Babylonia contained the oldest known record of applied geometry.

The tablet, known as “Si.427,” contains mathematical and legal records of land transactions at the time. It was discovered first in 1894 in what is now the province of Baghdad in Iraq—finding it proved to be a journey in itself for Mansfield, and efforts to decipher it tacked on further months of effort.

The tablet, similar to Plimpton 322, also displays the use of Pythagorean triples to make proper right angles. Si.427’s purpose regarding land has also led to researchers hypothesizing that one of the potential reasons Babylonians were interested in these more advanced forms of mathematics was to create accurate partitions and borders of their land.

The Babylonians created their own solutions, with the boundaries displayed on several additional tablets showcasing an apparent mastery of geographical and trigonometric properties. According to Dr. Mansfield, the Pythagorean triples used on the clay tablets is especially interesting because of their variety. An easy way to create a right angle is to create a triangle with a 3-4-5 pattern, with the largest number being attributed to the hypotenuse. The Babylonians used several different Pythagorean triples to accomplish the same goal, despite their numeric system making it particularly difficult and overall limiting in which triples can be created.

OUTLOOK: ANCIENT MATH AND ITS IMPACT ON THE FUTURE

From a historical perspective, the implications of these discoveries are relatively clear. The Babylonians possessed a significant understanding of geometry and trigonometry before it was even a thought in the minds of their alleged progenitors.

When it comes to Dr. Mansfield, his next move is to figure out the full extent of applications that ancient Babylonians used, what he refers to as, “proto-trigonometry” for. In addition to the information displayed on the front, Si.427’s backside contains a uniquely puzzling mystery that Mansfield hopes to soon crack. In large writing on the back of the tablet are the numbers: 25:29, written in this sexagesimal format. No one currently knows what these numbers mean, or even what they could potentially be referring to or measuring. However, Mansfield has stated he would like to work with other historians and mathematicians to develop theories as to what they may be.

“A race of Venus came to planet Earth millions of years ago”

The Ancient Astronaut theory is being taken more and more seriously by science. But who were these beings and where did they come from? According to a new hypothesis, some of these beings could come from Venus.

In recent years, the existence of extraterrestrial life in scientific nuclei has been discussed more , reaching the point of questioning whether we have not been visited for thousands of years. A new theory could show that beings from Venus came to Earth long before humans evolved.

Beings of Venus on Earth?

For decades, NASA has shown various aspects of the physical nature of Venus, thanks to space probes.

Spokesmen for exploration missions have stated that its environment is extremely hostile , with air laden with carbon dioxide and infernal barometric pressure . It also has a heat that exceeds 100 degrees Celsius along with dense clouds of sulfuric acid.

In short, on Venus it would be impossible for life to be born. But a declassified archive from 1989, which is practically unknown , could change our perception of that world.

The document relates to the different contacts that have existed between Earth and Venus and how the inhabitants of the latter came thousands of years ago , and continued to come to “meet” the human being.

They even talk about the “selection” of people they have had over the years, highlighting people from the field, the humble, even scientists and government officials.

This declassified document presents, then, a direct contradiction to what NASA has explained about the inhospitable nature of Venus.

Obviously, many people prefer to trust what science has said and forget everything that changes the official version .

However, there is a question … Why was a document that, supposedly, contradictory, was classified and kept hidden for more than 30 years?

Obviously, theorists around the world have started to make statements, blaming NASA and the elites for hiding information about space.

“They want to help humanity”

If scientists, the only ones with the ability to study beyond Earth’s borders, have lied to us in the past, why not distrust their information about Venus?

The possibility of life on Venus completely changes general thinking about our Solar System. This is because we have been led to believe that the galaxy is an immense desert with only one oasis; the earth.

Obviously, there is another possibility; that terrestrial technology is not advanced enough to locate life on that planet.

According to this report, we can understand that the civilization of Venus managed to solve all the problems that afflict humanity today. An example of this are wars, crime, corruption and other issues that do so much damage to society in general.

This is due to the development of peaceful collective values that are based on respect, understanding and love. Through their frequent contacts with different personalities on Earth, Venusians came to offer us help in solving all these issues that prevent us from evolving as humanity.

The problem is that this support is always accompanied by a request for the abandonment of weapons of mass destruction. Reason that makes us understand why this document has been classified and, subsequently, hidden.

If there is a developed civilization on Venus and NASA has hidden it or does not know of its existence, it is something that we will probably never know. However, if we manage to make contact with a civilization that supports us in our evolution, would we react correctly?

Mars' surface was carved by fast and furious floods from overflowing craters 3.5 billion years ago – with enough water released in a matter of weeks to completely fill Lake Superior, study finds

• Researchers show how 262 breached lakes on the Red Planet shaped its surface

• Water released at huge craters caused the formation of river valleys, they claim

• This water eroded the natural Martian sediment to leave the deep river valleys

• 3.5 billion years ago, water moved around Mars between crater lakes via rivers

By JONATHAN CHADWICK FOR MAILONLINE 

Mars' surface was carved by fast and furious floods from overflowing crater lakes 3.5 billion years ago, a new study says.

Researchers in Texas have used satellite images to determine how 262 breached lakes on the Red Planet shaped the Martian surface. 

The floods, which probably lasted mere weeks, eroded more than enough sediment to completely fill Lake Superior and Lake Ontario, they say. 

Although there's no liquid water on Mars today, about 4.3 billion years ago the Red Planet had enough water to cover its entire surface in a liquid layer about 450 feet (137 meters) deep, according to NASA.

Fast forward to 3.5 billion years ago, and this water was more scarce – channeled around the planet between crater lakes via rivers, much like on Earth today. 

Floods at these lakes created river valleys with high walls of jagged rock on either side, much like Earth's own impressive modern-day canyons.

Black lines indicate other river valleys formed by processes other than lake overflows. Image is approximately 400 miles (650 kilometres) across

Mars was not always a big dry rusty rock like it is today. Perhaps about 4.3 billion years ago, Mars would have had enough water to cover its entire surface in a liquid layer about 450 feet (137 meters) deep

'If we think about how sediment was being moved across the landscape on ancient Mars, lake breach floods were a really important process globally,' said lead author Tim Goudge, an assistant professor at the UT Jackson School of Geosciences, the University of Texas at Austin. 

'And this is a bit of a surprising result because they've been thought of as one-off anomalies for so long.'

The researchers think the furious floods were triggered either by the water filling up in the crater lake interior to the point where it started spilling over the edge; or as the lake filled up with water, the pressure from that water on the inside of the crater caused the crater rim to fail, allowing water to flow out.

'In either way, once the water started rushing out of the lake, it would begin rapidly carving an exit breach and canyon, allowing more water to flow out, and continuing so on in a runaway process until it eventually couldn't erode any more,' Professor Goudge told MailOnline.

The researcher also said he thinks more water was available early in Mars' early history, but that it never did completely cover the planet. 

On Earth, river erosion – the constant wearing away of the river bed and banks by the force of water – is usually a slow-going process. 

Over years and years, coastal land recedes as the force of the water breaks off sediment.  

But on Mars, massive floods from overflowing crater lakes had an outsized role in shaping the Martian surface, carving deep chasms and moving vast amounts of sediment.

Crater lakes were common on Mars billions of years ago when the Red Planet had liquid water on its surface. Some craters could hold a small sea's worth of water. 

But when the water became too much to hold, it would breach the edge of the crater, causing catastrophic flooding that carved river valleys in its wake. 

A 2019 study led by Goudge, published in the in the journal Geology, determined that these events happened rapidly. 

Remote sensing images taken by satellites orbiting Mars have allowed scientists to study the remains of breached Martian crater lakes.

However, the crater lakes and their river valleys have mostly been studied on an individual basis, Goudge said.

This is the first study to investigate how the 262 breached lakes across the Red Planet shaped the Martian surface as a whole.

For the study, the researchers reviewed a preexisting catalog of river valleys on Mars and classifying them into two categories – valleys that got their start at a crater's edge and valleys that formed elsewhere on the landscape. 

Valleys that got their start at a crater's edge indicates they formed during a lake breach flood, while valleys that formed elsewhere on the landscape suggests a more gradual formation over time. 

From there, the scientists compared the depth, length and volume of the different valley types and found that river valleys formed by crater lake breaches erode nearly a quarter of the Red Planet's river valley volume despite making up only 3 per cent of total valley length.

'This discrepancy is accounted for by the fact that outlet canyons are significantly deeper than other valleys,' said study co-author Alexander Morgan, a research scientist at the Planetary Science Institute in Tucson, Arizona.

At 559 feet (170.5 meters), the median depth of a breach river valley is more than twice that of other river valleys created more gradually over time, which have a median depth of about 254 feet (77.5 meters).

In addition, although the chasms appeared in a geologic instant, they may have had a lasting effect on the surrounding landscape. 

Floods at Martian lakes created river valleys with high walls of jagged rock on either side, much like the impressive canyons on Earth today. Pictured, the Colorado River as it flows through Marble Canyon prior to entering the infamous Grand Canyon in northern Arizona

The study suggests that the breaches scoured canyons so deep they may have influenced the formation of other nearby river valleys. 

The authors said this is a potential alternative explanation for unique Martian river valley topography that is usually attributed to climate.   

On Earth, river erosion is a slow and steady process in most cases, but that doesn't mean it will work that way on other worlds, according to Goudge. 

'When you fill [the craters] with water, it's a lot of stored energy there to be released,' Goudge said. 'It makes sense that Mars might tip, in this case, toward being shaped by catastrophism more than the Earth.' 

The new study has been published today in the journal Nature. 

WAS MARS EVER HOME TO LIQUID WATER?

In September of the same year, the first scoop of soil analysed by Curiosity revealed that fine materials on the surface of the planet contain two per cent water by weight.

In 2017, Scientists provided the best estimates for water on Mars, claiming it once had more liquid H2O than the Arctic Ocean - and the planet kept these oceans for more than 1.5 billion years.

The findings suggest there was ample time and water for life on Mars to thrive, but over the last 3.7 billion years the red planet has lost 87 per cent of its water - leaving it barren and dry.

Lake Breach Floods Eroded Surface of Early Mars, Study Says

Massive floods from overflowing crater lakes were responsible for eroding at least 24% of the volume of incised valleys on early Mars, according to new research led by University of Texas at Austin planetary scientists.

“If we think about how sediment was being moved across the landscape on ancient Mars, lake breach floods were a really important process globally,” said Dr. Tim Goudge, a researcher at the University of Texas at Austin and CIFAR.

“And this is a bit of a surprising result because they’ve been thought of as one-off anomalies for so long.”

Crater lakes were common on Mars billions of years ago when the planet had liquid water on its surface. Some craters could hold a small sea’s worth of water.

But when the water became too much to hold, it would breach the edge of the crater, causing catastrophic flooding that carved river valleys in its wake.

In 2019, Dr. Goudge and colleagues determined that these events happened rapidly.

“However, the crater lakes and their river valleys have mostly been studied on an individual basis. This is the first study to investigate how the 262 breached lakes across the Red Planet shaped its surface as a whole.”

The authors classified the Martian river valleys into two categories: (i) valleys that got their start at a crater’s edge, which indicates they formed during a lake breach flood; and (ii) valleys that formed elsewhere on the landscape, which suggests a more gradual formation over time.

From there, they compared the depth, length and volume of the different valley types and found that river valleys formed by crater lake breaches punch far above their weight, eroding away nearly a quarter of the planet’s river valley volume despite making up only 3% of total valley length.

“This discrepancy is accounted for by the fact that outlet canyons are significantly deeper than other valleys,” said Dr. Alexander Morgan, a researcher at the Planetary Science Institute.

At 170.5 m (559 feet), the median depth of a breach river valley is more than twice that of other river valleys created more gradually over time, which have a median depth of about 77.5 m (254 feet).

New Ultrahot Jupiter Contains Iron in Its Atmosphere

by Natali Anderson

Astronomers have discovered a highly-irradiated gas giant exoplanet in close-in, highly misaligned orbit around a bright star called TOI-1518.

An artist’s rendition of the ultrahot Jupiter TOI-1518b and its parent star.

Image credit: Sci-News.com.

TOI-1518 is a fast-rotating F-type star located approximately 742 light-years away in the constellation of Cepheus.

Also designated as TIC 427761355 and BD+66 1610, it is almost two times larger and more massive than the Sun.

The newfound planet, TOI-1518b, is an inflated gas giant about 1.9 times the size of Jupiter.

It orbits its parent star once every 1.9 days at a distance of 0.04 AU (astronomical units).

“The new planet falls within the category of ultrahot Jupiters, which have equilibrium temperatures exceeding 2,000 K,” said Yale University astronomer Samuel Cabot and colleagues.

“Many ultrahot Jupiters contain vaporized metals, both neutral and ionized, in their upper atmospheres.”

“These metals and molecules containing them are recognized as strong sources of opacity in the optical and near-ultraviolet regions.”

TOI-1518b was first identified as a candidate transiting exoplanet in photometric data from NASA’s Transiting Exoplanet Survey Satellite (TESS).

The presence of the planet was then confirmed using high-resolution optical transmission spectra from the EXtreme PREcision Spectrometer (EXPRES) on the Lowell Discovery Telescope.

Additionally, Cabot and co-authors detected iron vapor in the atmosphere of TOI-1518b.

“TOI-1518b is highly inflated, which makes it amenable to intensive atmospheric characterization,” they said.

“The equilibrium temperature of TOI-1518b (2,492 K) is in the regime where the planet might exhibit a thermal inversion.”

“This, combined with the brightness of the host star, makes TOI-1518b an attractive target for follow-up emission spectroscopy.”

The team’s paper will be published in the Astronomical Journal.

Jupiter’s Great Red Spot has always been a mysterious feature and now it’s getting even stranger with stronger winds. NASA’s Hubble Space Telescope collected the data regarding the discovery of the accelerating wind speeds.

Jupiter’s massive storm, which is known as the Great Red Spot, is located in the southern hemisphere of the planet. It was first spotted in 1831 by amateur astronomer Samuel Heinrich Schwabe; however, it could be much older than that. The crimson-colored clouds of the storm rotate in a counter-clockwise direction with speeds that are more powerful than 400 miles per hour (644 kilometers per hour). It has been shrinking in size and turning into a more circular shape rather than an oval. It has a diameter of about 10,000 miles (a little over 16,000 kilometers) which means that Earth could still fit inside of the storm.

By studying Hubble’s “storm reports”, researchers noticed that the wind speed just inside of the storm’s boundaries (this area is called the high-speed ring) accelerated as much as 8% from 2009 to 2020. On the other hand, the wind speeds close to the center of the storm are actually slower.

More specifically, Hubble detected that the wind speeds changed less than 1.6 miles per hour (2.6 kilometers per hour) each year as explained by Amy Simon from NASA’s Goddard Space Flight Center in Greenbelt, Maryland, “We’re talking about such a small change that if you didn’t have eleven years of Hubble data, we wouldn’t know it happened.” “With Hubble we have the precision we need to spot a trend.”

Michael Wong, who is from the University of California, Berkeley, and who led the analysis, noted, “We find that the average wind speed in the Great Red Spot has been slightly increasing over the past decade,” adding, “We have one example where our analysis of the two-dimensional wind map found abrupt changes in 2017 when there was a major convective storm nearby.”

While it’s very interesting that the wind speeds have picked up, experts are uncertain as to what it means for the storm’s future as Wong stated, “That’s hard to diagnose, since Hubble can’t see the bottom of the storm very well. Anything below the cloud tops is invisible in the data.” “But it’s an interesting piece of data that can help us understand what’s fueling the Great Red Spot and how it’s maintaining energy.”

For now, Jupiter’s Great Red Spot is continuing to amaze and baffle experts at the same time. A video and images of the wind changes in the Gas Giant’s massive storm can be seen here.

By analyzing images taken by NASA's Hubble Space Telescope from 2009 to 2020, researchers found that the average wind speed just within the boundaries of the Great Red Spot, set off by the outer green circle, have increased by up to 8 percent from 2009 to 2020 and exceed 400 miles per hour. In contrast, the winds near the storm's innermost region, set off by a smaller green ring, are moving significantly more slowly. Both move counterclockwise.

Are NASA, the other space agencies and private space companies wasting their time focusing on finding signs of life on Mars and using this to justify and/or air creating human settlements there? That may be the case if you listen to researchers from the Washington University in St. Louis who say size matters when it comes to life on other planets and Mars is just too small to have it or sustain it because it’s too tiny to have water.

“Mars’ fate was decided from the beginning. There is likely a threshold on the size requirements of rocky planets to retain enough water to enable habitability and plate tectonics, with mass exceeding that of Mars.”

In a university press release announcing the publication of a new study in the Proceedings of the National Academy of Sciences, Kun Wang, assistant professor of earth and planetary sciences in Arts & Sciences and senior author of the study explains how his team reached its conclusion about Mars being more like a dried pit than a juicy life-supporting olive. While the non-natural water-filled ‘canals’ that astronomers of the 19th and 20th centuries believed they saw on the Martian surface have been proven to be optical illusions, Martian rocks and Martian meteors found on Earth show solid evidence that the planet once had natural rivers and channels. However, the most recent explorations have found no water on the Martian surface. Wang and his colleagues turned to an unexpected element to resolve this discrepancy – potassium (K).

Did Mars ever look like this?

“This study presents K isotope data from a spectrum of martian lithologies as an isotopic tracer for comparing the inventories of highly and moderately volatile elements and compounds of planetary bodies. Here, we show that meteorites from Mars have systematically heavier K isotopic compositions than the bulk silicate Earth, implying a greater loss of K from Mars than from Earth.”

The team used stable isotopes of potassium (K) to estimate volatile elements and compounds — including water — on planets, satellites and large asteroids. They found that Mars, Earth, the Moon and the asteroid 4-Vesta had large amounts of volatile elements compounds when they were formed, but Mars lost more than Earth, and the Moon and 4-Vesta lost more than both. The evidence pointed to size as the deciding factor for how much water a planet or space rock retained. For the Red Planet, Wang says the key was the Martian meteorites found on Earth.

“Those Martian meteorites have ages varying from several hundred millions to 4 billion years and recorded Mars’ volatile evolution history. Through measuring the isotopes of moderately volatile elements, such as potassium, we can infer the degree of volatile depletion of bulk planets and make comparisons between different solar system bodies.”

Wang points out that those meteorites also dispute a prevailing theory that Mars once had even more water than Earth. As a result, astronomers now have an easy technique for determining if an exoplanet in a star’s habitable “Goldilocks” zone is a good prospect for life.

“The size of an exoplanet is one of the parameters that is easiest to determine. Based on size and mass, we now know whether an exoplanet is a candidate for life, because a first-order determining factor for volatile retention is size.”

Sorry, Mars — you may not even have enough to fill the bottle

Which brings us back to Mars. Although it’s in the Sun’s habitable zone, this study’s results make Mars too small to retain water for life. Should space agencies and companies move on to another planet or Moon? Good luck convincing them to abandon exploring the planet that has captured the imagination of astronomers and science fiction fans for centuries. Venus may be closer, but they can at least see where they’re going on Mars. Even if it doesn’t have enough water, the experience will prepare space travelers for the next longer mission to a better candidate.

Sorry, Mars … size matters.

According to a new study conducted by Chinese astronomers, there could be as many as a million small asteroids heading towards our planet within the next century. But apparently there’s no need to panic as the impact risk is low and the majority of the asteroids are less than 100 meters in width (328 feet). On the other hand, they if they do impact our planet, they would have more kinetic energy than what is in an atomic bomb.

he current number of known asteroids is 1,113,527 – some measuring as large as hundreds of miles in diameter while the smaller ones are less than 33 feet (10 meters) in width. Most of the known asteroids are located in the asteroid belt between Mars and Jupiter. In fact, there are an estimated 1.1 to 1.9 million asteroids located there that are bigger than 1 kilometer in diameter (0.6 miles) with millions of smaller space objects.

Professor Gan Qingbo and colleagues at the Space Debris Observation and Data Application Centre at the China National Space Administration stated that the short-term hazardous asteroids (SHA) are very hard to track in space as they explained, “The accurate identification of impact threat targets and early warning capabilities requires more precise algorithms for orbit determination and impact risk assessment.”

The researchers looked through a global asteroid database and focused on the orbits of smaller asteroids and they discovered that over 700 of them could potentially hit our planet in the next century. Five of the asteroids had a one in a thousand chance of impacting our planet, although their constantly changing orbits could affect those probabilities. Then they conducted physical models on asteroid formation and estimated that there could be between 100,000 and a million short-term hazardous asteroids lurking around.

Since a lot of astronomers focus their attention on much larger space objects, they could be ignoring the smaller asteroids that may also be potentially dangerous. For example, a small asteroid measuring just 19 meters (62 feet) exploded over Chelyabinsk, Russia, in 2013 but it still caused an extremely powerful explosion that was approximately 30 times stronger than the Hiroshima blast. Furthermore, the shock waves caused damage to over 7,200 buildings but thankfully nobody died.

This is a perfect example of a small asteroid causing significant damage. There is no reason for us to run for cover though as Professor Chen Ping, who is a Guangzhou-based geologist with the Chinese Academy of Sciences, explained that the SHAs are “an interesting topic for academic research and public discussions, but that should be as far as it goes,” and that since they are so small, they would probably just burn up in our atmosphere. Let’s hope he’s right.

Even the Quiet Supermassive Black Holes are Blasting out Neutrinos and Gamma Rays

Is there anywhere in the Universe where we can escape from radiation? Certainly not here on Earth. And not in space itself, which is filled with diffuse radiation in the form of gamma rays and neutrinos. Scientists have struggled to explain where all those gamma rays and neutrinos come from. A trio of researchers is proposing a source for all that radiation in a new paper: resting black holes.

Supermassive Black Holes (SMBH) likely reside in the center of every large galaxy like the Milky Way. When those SMBHs are actively accreting matter they can spew out a lot of radiation across the entire spectrum, from radio waves to gamma rays. When that happens they’re called active galactic nuclei. But what about SMBHs that are quiet?

A new study says even quiescent SMBHs are emitting gamma rays and neutrinos. The discovery helps explain why the Universe is awash in energetic particles.

The title of the paper is “Soft gamma rays from low accreting supermassive black holes and connection to energetic neutrinos.” It’s published in the journal Nature Communications, and the lead author is Shigeo Kimura from Tohoku University in Sendai, Japan.

Neutrinos are nearly massless subatomic particles and are electrically neutral, which is where they get their name. As a result, their gravitational interaction is near zero, and they don’t interact with the strong nuclear force either. They’re extremely difficult to detect, and they’re passing through your body right now.

Gamma rays, on the other hand, are not difficult to detect. They’re the most energetic photons in the Universe and you definitely don’t want any passing through your body. They’re released in atomic bomb detonations, among other things. Space-based detectors have found gamma rays with voltages in the gigaelectron range. If electron volt ranges aren’t your thing, just think of them as more energetic than visible light by orders of magnitude.

So scientists know a lot about both neutrinos and gamma rays, they just aren’t sure where they all come from. This research might have the answer. “The Universe is filled with a diffuse background of MeV gamma-rays and PeV neutrinos, whose origins are unknown. Here, we propose a scenario that can account for both backgrounds simultaneously,” the authors write.

Scientists think they know where powerful background gamma-rays in the gigaelectron volt (GeV) to teraelectron (TeV) volt ranges come from. They come from AGNs and probably star-forming galaxies. But the source of softer gamma-rays, those in the megaelectron volt (MeV) ranges are unknown. Same with many neutrinos.

This paper shows that low luminosity galactic nuclei could account for both the neutrinos and the gamma rays.

A black hole’s enormous mass and gravitational pull draws matter toward it. It forms an accretion disk of swirling matter, and eventually, the matter falls into the black hole. When that happens an enormous amount of gravitational energy is released. That energy heats up gas around the hole and creates plasma. In this case, the low-accreting black hole has insufficient cooling and the plasma’s temperature can reach tens of billions of degrees Celsius.

What happens is the plasma energizes protons to an extreme degree. They can be 10,000 times more energetic than what the Large Hadron Collider (LHC) can achieve, and the LHC is our most powerful particle accelerator. As these high-speed protons interact with matter and radiation, they produce neutrinos. This can account for the higher energy range neutrinos detected in space.

A similar mechanism produces gamma-rays. As the electrons reach extremely high temperatures, they become efficient producers of gamma-rays in the MeV range through a process called Comptonization.

So the high-temperature plasma around quiet black holes can produce neutrinos and gamma-rays. Even though these types of black holes are dim and difficult to see, there are a lot of them. It’s reasonable to think they could account for background radiation in the form of gamma-rays and neutrinos.

But this is just a proposed mechanism. There’s no conclusive proof yet. Where will that come from?

Most of our gamma-ray detectors aren’t tuned to the MeV frequency. They’re tuned to higher energy levels. What’s needed is what the authors call a “multimessenger” detector. That’s a detector that detects both gamma-rays and neutrinos at the same time, in the right energy ranges. Proposed missions like e-ASTROGAM, the All-sky Medium Energy Gamma-ray Observatory (AMEGO), and the Gamma-Ray and AntiMatter Survey (GRAMS) should help.

Aging White Dwarfs Become Even More Magnetic

In a few billion years the Sun will end its life as a white dwarf. As the Sun runs out of hydrogen to fuse for energy it will collapse under its own weight. Gravity will compress the Sun until it’s roughly the size of Earth, at which point a bit of quantum physics will kick in. Electrons from the Sun’s atoms will push back against gravity, creating what is known as degeneracy pressure. Once a star reaches this state it will cool over time, and the once brilliant star will eventually fade into the dark.

Most stars in the universe will end as a white dwarf. Only the largest stars will explode as supernovae and become neutron stars or black holes. There are lots of white dwarfs in the Milky Way, but many of them can be difficult to study.

For one thing, white dwarfs don’t produce energy in their cores as regular stars do. They cool and fade as they age, so we tend to see the youngest and brightest white dwarfs. Observations of white dwarfs are also biased toward those with the smallest mass. That’s because the more massive a white dwarf is, the smaller it is. The reason for this has to do with the balance between electron degeneracy pressure and gravity. In a white dwarf, the electrons act as a sort of quantum gas. The more massive the white dwarf, the more tightly its gravity can squeeze the electrons, hence a smaller volume.

Fortunately, we’re getting better at studying smaller and cooler white dwarfs, as a recent study shows. The team used data from the Gaia spacecraft to find white dwarfs within 20 parsecs of Earth. In addition to known white dwarfs, the team identified about 100 white dwarfs that had never been cataloged. They then looked at the spectrum of these white dwarfs using ISIS spectrograph and polarimeter on the William Herschel Telescope. Since the spectrum of a white dwarf is affected by its magnetic field, the team was able to measure the strength of their magnetic fields.

They found an interesting result. There is a correlation between the age of a white dwarf and its magnetic field. The older a white dwarf is, the more likely it has a strong magnetic field. In other words, white dwarfs tend to become more magnetic as they age. This suggests that white dwarf magnetic fields are created through the cooling process of the star.

On September 24, Dr. Michael Salla received a new update about recent developments in Antarctica concerning former Dark Fleet bases taken over by China, and how these were being turned over to the Earth Alliance as a result of the Jupiter Agreements. 

The update was released by Val Nek, from the Galactic Federation of Worlds, through Megan Rose who again relayed the information.  

The video below is an audio version of an article published on Sept 27, 2021, and narrated by the author Dr. Michael Salla. 

Update 2: Michael Salla - Interesting synchronicity. 

Today I received Ben Fulford's latest update. His sources are telling him a major East/West agreement has just been reached involving China, which has joined a massive tech project to improve the planet. 

That corroborates the update just received from Val Nek about China joining the Earth Alliance, and now working for common purposes for planetary defense, building a planetary starfleet, mass producing and releasing advanced healing technologies, etc. 

This kind of independent corroboration is always helpful when trying to substantiate events taking place behind the scenes.

“Abandon Earth”: The Alleged Message Received by Voyager 2

An alleged alien binary code message was downloaded by a US NCO, and appears to contain a shocking warning to humanity.

The famous American researcher Linda Moulton Howe translated some of these binary codes thanks to the support of a US Army sergeant.

It was launched on August 20, 1977 by NASA aboard the Titan-Centaur rocket, just before its sister probe, Voyager 1, in an orbit that would eventually take it to visit the main planets of the Solar System.

But during its journey through the solar system, the probe was allegedly tampered with, and it suddenly changed the encoding of messages sent to Earth.

The anomaly began on April 22, 2010 and among the most disturbing hypotheses, they relate it to an extraterrestrial sabotage. 

CJ’s message reads as follows:

Continuing protection of humanity 49.27n
11.5e. Exposing Hidden Knowledge to ALL Citizens’ Advancement Imperative for Planetary Survival
Orion Attention 1,350.3 39,170
Avoid Sending (Signals) or Messages

NASA expert Kevin Baines, who is leading the mission, said that “it appeared that someone had taken control of the spacecraft and reprogrammed the probe, so we may not yet know the whole truth.”

Later, Kevin Baines reported that the probe was located about 15 billion kilometers from Earth and suddenly began sending data in a language that none of the experts could understand.

This can only happen in one case: “someone has changed the probe’s communication system”, and if so, we would be talking about another civilization that is navigating the cosmos.

From an analysis performed by the reception of Voyager 2’s encrypted signals, it was observed with amazement that the binary code of the probe’s communication system was changed from 0 to 1.

NASA noted that the rest of the probe’s onboard system had not undergone any modifications – reboot, reprogramming, and reboot – and therefore work continues as usual.

But what seems to have changed is the communication system … that has sent a message to Earth that supposedly says: “Leave Earth.”
