In the midst of all the crazy things that have happened in our pandemic year, it’s easy to lose track of other developments. But despite the hardship of the lockdowns and the pandemic itself, the world isn’t sitting still. We’ve seen some stunning advancements not related to the pandemic, including some very nifty gadgets. Here are just some of them.

1. The robot dog by the name of Spot

Remember those unsettling robot dog videos trying to go down stairs and open doors? Spot is their leader. The robot by Boston Dynamics has been in development for a few years now, but it’s gone on sale in 2020, for the hefty sum of $74,500 — and this was also the year that Spot was really put to good use.

Spot is agile, robust, and can navigate rugged terrain with unprecedented mobility. Its software is downloadable and upgradeable (available on GitHub) if you’re up for the task, and are willing to pay the price of a luxury car to get the robot itself.

Spot isn’t exactly a companion (though he can also play that part, and he’s a pretty good dancer actually) — he’s more of a utility dog. From patrolling hazardous sites and abandoned buildings to monitoring construction sites and offshore oil rigs, Spot can be sent where it would be too dangerous for humans. Different companies (and even governments) are already putting the robot dog to good use. For instance, Spot is patrolling the parks of Singapore warning people to not stay too close to each other.

A little bit dystopian? Maybe. Useful? Definitely.

2. Drones taking to the oceans

Drones are as cool and useful as ever (and they’re actually becoming more and more present in science and environmental monitoring), but they’re not exactly a new gadget. Well, at least air drones. Underwater drones, however, are pretty new and interesting.

An underwater drone is a submarine in the same sense a ‘regular’ drone is a helicopter. Biologists have been using ROVs (Remotely Operated underwater Vehicles) for a few years to study corals, fish, and explore the subsurface — now, you can get your own version. Several companies are already working in the field, but US-based Geneinno seems to be one of the pioneers in the field, and their ROVs (or underwater drones, which just sounds better) are now available to the public.

3. The Lego Bugatti

Nowadays, you can build anything and everything from Lego — but few things are as awesome as the company’s Technic branch. You basically build your own, realistic and fancy model cars, from the likes of a Ferrari or a Lamborghini to a Jeep Wrangler or even a race plane.

The cars have accurate real-life functions, such as a gearbox and a steering wheel, connected just like the real thing (there’s even a Lego engine). This is not for the inexperienced builder and not for those without patience, but it can make for a stunning little home gadget. But if you’re looking to build your own Lego fancy car, this is as good as it gets in 2020.

4. The Raspberry Pi Compute Module 4 — a card-sized computer

What you see here, just slightly bigger than a coin, is a full-on computer — and it goes for about $25. The Raspberry Pi Foundation is already well-known to those interested in the Internet of Things (IoT) and gadgets, as well as those looking for cheap computing alternatives.

Raspberry Pi’s are small, single-board computers that can function either stand-alone, or as part of other applications (typically involving some form of sensors). The new mini version includes a 64-bit quad-core processor, graphics support, hardware decoder, HDMI ports, USB ports, a PCI interface, camera interfaces, at least a gigabyte of memory, flash storage, clock and battery backup, a wireless option, an ethernet option. If you’d like to start diving into the world of IoT or just getting started with some offbeat computing, this is definitely one of the best places to start — and it won’t break your budget either.

5. Futuristic AI fitness work-from-home mirrors

Staying fit is never easy, especially in a year like this when we’ve had to deal with the pandemic and all the stress and uncertainty — while mostly staying home. But somehow, one feels that having a futuristic AI mirror assistant could help with that.

The new Forme by Fuseproject is a 43-inch screen with 4k resolution and stowable arms for resistance training. It’s your very own one-on-one personal assistant working out with you in the comfort of your home. You can do various types of resistance training, and the screen helps you see what your virtual trainer is doing and try to do the same thing (you can also see yourself and improve your form). You can opt for pre-recorded workouts or a specialized routine, but the machine’s AI also analyzes your workout schedule and progress and constantly tweaks and adapts for optimum performance.

6. The world’s first graphene headphones

Since its recent discovery, graphene has been touted as a wonder material with myriad applications ranging from renewable energy to spacesuits. While graphene has undoubtedly had an important impact on science, we, the profane consumers, are happy to see it make an impact on something more down to earth: music.

Ora headphones are the world’s first graphene headphones, supported by one of the very inventors of graphene, Nobel Laureate Konstantin Novoselov, and they’re one of the first graphene products to hit the shelves. The quality of the headphones shows in the sound quality, and the design is quite unique.

7. The Robot kitchen

Robots can already do many things, but if they can’t cook a good dinner, how good are they really? Well luckily, that’s no longer a problem — at least if you can spare a six figure sum for the fully automated Moley kitchen. The system features two robotic arms and an array of sensors and cameras that not only cook your meal but also wash everything after they’re done.

For now, the system can produce 30 dishes (all developed by top chefs), but the digital menu will soon be expanded to over 5,000 choices. It’s truly one robot worth sinking your teeth into.

8. A wearable sensor that tells you what’s in your blood

Image credits: Robson Rosa da Silva.

This noninvasive skin-adherent sensor printed on microbial nanocellulose is essentially a 1.5 by 0.5 cm thin sheet that can detect a range of biomarkers, from sodium and potassium to lactic acid and glucose. It can even be used to track the level fo atmospheric pollutants. In addition to medical uses, it could, for instance, be used when working out (to tell you when you should take it easy), or for detecting glucose and warning when you should lay off the cake.

To make things even better, the material is breathable and doesn’t include plastic. The Brazilian researchers who developed it are now looking to see what products would offer the best integration.

9. The Smart Garden 6

Let me guess — you’re still using plastic pots to grow plants in? That’s so 2019. This small, chique automated plant grower by the Finnish Design Shop lets you grow your own herbs and salads with minimum hassle.

Not only does it pump its own water from time to time (you just need to fill the tank), but it also has 18 high-end LED lights which ,according to the producer, “provide the best spectrums and intensity needed to create perfect germination and growth conditions for your greens”

These are some of my personal favourite space-related breakthroughs and research that have come about this year. The list is by no means exhaustive.

1. Black Holes go silent

In terms of black hole science, 2019 was always going to be a difficult year to top being the year that brought us the first direct image of a supermassive black hole (SMBH). That doesn’t mean that 2020 has been a slow year for black hole developments, however.

One of the most striking and memorable examples of black hole research announced this year was the discovery of a ‘silent’ black hole in our cosmic ‘back yard.’ An international team led by researchers from European Southern Observatory (ESO) including found the black hole in the system HR 6819, located within the Milky Way and just 1,000 light-years from the Earth.

The observation marks the closest to Earth a black hole has ever been discovered and Dietrich Baade, Emeritus Astronomer at ESO in Garching believes that it is just ‘the tip of the Iceberg’.

“It’s remarkable because not only is it the first of its kind found, but it’s also so nearby,” said Baade. “Discovering a first only an astronomical stone’s throw away is the biggest surprise one can probably imagine.”

The black hole was described as ‘silent’ by the team because it is not current accreting material — the destructive process that creates powerful x-ray emissions and makes these light-trapping objects observable.

“If there is one, there ‘must’ be more,” Baade remarked in May. “If the Earth is not in a privileged position in the Universe — and all available evidence suggests without a doubt it is not — this means that there must be many more silent black holes.”

Baade also remarked that as current cosmological models suggest that the number of stellar-mass black holes is between 100,000,000 to 1,000,000,000 and we have observed nowhere near this many objects, more quiet black holes are “badly needed” to confirm current models. “HR 6819 is the tip of an iceberg, we do not yet know how big the iceberg is.”

Silent black holes weren’t the only examples of this hind of science making noise in 2020, however. Long-missing Intermediate Mass Black Holes were discovered. And just like a proverbial bus, you wait decades for one and then two turn up at once.

2. Intermediate mass black holes found and found again

Missing black holes were the subject of another piece of exciting space science in September 2020, when researchers from the VIRGO/LIGO collaboration discovered the tell-tale signal of an intermediate-mass black hole (IMBH) in gravitational-wave signals. To add to the excitement, the signals originated from the largest black hole merger ever observed.

The merger — identified as gravitational wave event GW190521 —was detected in gravitational waves and is the first example of a ‘hierarchical merger’ occurring between two black holes of different sizes, one of which was born from a previous merger.

“This doesn’t look much like a chirp, which is what we typically detect,” Virgo member Nelson Christensen, a researcher at the French National Centre for Scientific Research (CNRS) said when announcing the team’s observation. “This is more like something that goes ‘bang,’ and it’s the most massive signal LIGO and Virgo have seen.”

The black hole birthed in the detected merger appears to have a mass of between 100–1000 times that of the Sun — most likely 142 solar masses — putting it in the mass range of an IMBH — a ‘missing link’ between stellar-mass black holes and much larger SMBHs.

Earlier in 2020, another team had used the Hubble Space Telescope X-ray data collected in 2018 to identify what they believed to be an IMBH with a mass 50,000 times that of the Sun named 3XMM J215022.4−055108 (or J2150−0551 for short).

Whether GW190521 or J2150−0551 will go down in history as the first discovered IMBH is currently a little muddy, but what is less questionable is that 2020 will go down as the year in which these ‘missing link’ black holes were first discovered, bringing with them exciting implications for the future investigation of black holes of all sizes.

“Studying the origin and evolution of the intermediate-mass black holes will finally give an answer as to how the supermassive black holes that we find in the centres of massive galaxies came to exist,” said Natalie Webb of the Université de Toulouse in France, part of the team that found J2150−0551. And IMBHs weren’t the only missing element of the Universe that turned up in 2020.

3. Discovering the Universe’s missing mass

In May astronomers, including Professor J. Xavier Prochaska of UC Santa Cruz, announced that they had found the missing half of missing baryonic matter demanded by cosmological models.

“The matter in this study is ‘ordinary’ matter — the material that makes up our bodies, the Earth, and the entirety of the periodic table. We refer to this matter as ‘baryonic’–matter made up of baryons like electron and protons,” Prochaska said when he spoke exclusively to ZME Science earlier this year. “Of particular interest to astronomers is to ascertain the fraction of the material that is tightly bound to galaxies versus the fraction that is out in the open Universe — what we refer to as the intergalactic medium or cosmic web.”

The matter the team discovered isn’t ‘dark matter’ — which accounts for roughly 85–90% of the Universe’s matter content — but rather ‘ordinary’ matter that has been predicted to exist by our models of universal evolution but has remained hidden.

The team made the discovery using mysterious Fast Radio Bursts (FRBs) and the measurement of the redshift of the galaxy from which they originate as a detection method. FRBs can be used as a probe for baryonic matter because as they travel across the Universe, every atom they encounter slows them down by a tiny amount.

This means that they carry with them a trace of these encounters along with them in the spectral splitting as seen above. This allowed the team to infer the presence of clouds of ionised gas that are invisible to ‘ordinary’ astronomy because of how diffuse they are.

4. Asteroid Samples Returned by Hayabusa2

Japan’s Hayabusa2 probe and its continued investigation of the asteroid Ryugu has been the gift that has just kept giving in 2020. Just this month the probe returned to Earth samples collected from an asteroid — which has an orbit that brings it between Earth and Mars — for the first time.

Though probes have landed on asteroids and collected samples before, these samples have been examined in situ. Thus this is the first time researchers have been able to get ‘up close and personal’ with matter from an asteroid.

Hayabusa2 arrived at Ryugu in late June 2018, making its touch-down on the surface of the asteroid in February of the following year after months careful manoeuvring conducted by the Japan Aerospace Exploration Agency (JAXA) and the selection of an optimal region from which to collect samples.

Ahead of the return of samples on December 5th, the probe sent back some stunning images of the asteroid’s surface. These images were more than purely aesthetic, however. Examination of dust grains on the surface of Ryugu gave the team, including Tomokatsu Morota, Nagoya University, Japan, indications of a period of rapid heating by the Sun.

“Our results suggest that Ryugu underwent an orbital excursion near the
Sun,” said Morota in May. “This constrains the orbital transition processes of asteroids from the main belt to near-Earth orbit.”

Impressive though this achievement is, its the collection of samples from the asteroid and their subsequent safe return to earth that is the ‘main course’ of the Hayabusa2 mission. “The most important objective of the touchdown is sample collection from Ryugu’s surface,” Morota explained.

It is hoped that access to these samples will help answer lingering questions about asteroid composition as well as assisting researchers to confirm Ryugu’s suspected age of 100 million years old — which actually makes it quite young in terms of other asteroids.

Asteroids like Ryugu can act as a ‘snapshot’ of the system’s in which they form at the time of that formation. This is because whereas planets undergo a lot of interaction with other bodies, asteroids remain pretty much untouched.

Whilst researchers will no doubt be elated by the return of the Ryugu samples and the continuing success of the Hayabusa2 mission, 2020 wasn’t all good news for fans of asteroid research.

5. Goodbye to Arecibo

The iconic radio telescope at the Arecibo Observatory in Puerto Rico collapsed at the beginning of December, ahead of its planned demolition. The telescope which will be familiar to moviegoers as the setting of the climactic battle in Pierce Brosnan’s first outing as James Bond, 1995’s Goldeneye, had been in operation up until November, playing a role in the detection of near-Earth asteroids and monitoring if they present a threat to the planet.

The collapse of the radio telescope’s 900-tonne platform which was suspended above the telescope’s 305-metre-wide dish, on December 1st, followed the snapping of one of its main cables in November.

The US National Science Foundation (NSF), which operates the observatory had announced that same month that the telescope would be permanently closed citing ‘safety concerns’ after warnings from engineers that it could collapse at any point.

Following the collapse, the NSF release heart-wrenching footage of the radio telescope collapsing recorded by drones. The footage shows cables snapping at the top of one of the three towers from which the instrument platform was suspended. The platform then plummets downward impacting the side of the dish.

The observatory had played a role in several major space-science breakthroughs since its construction in 1963. Most notably, observations made by the instrument formed the basis of Russell A. Hulse and Joseph H. Talyor’s discovery of a new type of pulsar in 1974. The breakthrough would earn the duo the 1993 Nobel Prize in Physics.

Some good could ultimately come out of the collapse of Arecibo. Questions had been asked about the maintenance of the radio telescope for some time and the fact that the cable which snapped in November dated back to the instrument’s construction 57 years ago has not escaped notice and comment.

As a result, various space agencies are being encouraged to make efforts to better maintain large-scale equipment and facilities so that losses like this can be avoided in the future.

For most of us, 2020 is going to be a year that we would rather forget. Whilst very few of us come honestly comment that we have had anything approaching a ‘good year’ space science has plowed ahead, albeit mildly hindered by the global pandemic.

Our knowledge and understanding of space science are better off at the end of 2020 than it was twelve months earlier, and that is at least something positive that has emerged from this painful year.
