Scientists have gathered a significant chunk of a distant asteroid, which has made its way to Earth after a mission taking millions of miles. But the really useful work will begin now. Nasa’s Osiris-Rex mission flew to the distant Asteroid Bennu, scooped up a piece of the object into a canister, and then flew back to Earth to drop it off. On Sunday, Nasa picked up that canister in the Utah desert and is now working to secure it. It will then send those samples to a variety of scientists around the world, with a chunk of it being sent to more than 200 people at 38 different institutions across the world. They hope that they can use them as a “time capsule” to peer into the early universe, telling us about where we came from. “This box when it is opened of material from the surface of Bennu can tell us untold secrets of the origins of the universe, the origins of our planet and the origins of life itself,” said Queen musician Brian May, who helped with the research by mapping out the asteroid to find a landing spot. “What an incredibly exciting day.” Sample return missions are particularly exciting to scientists because they offer a look at a pristine piece of a distant world that has been undisturbed by the environment on Earth. While some pieces of asteroids and other objects can fall down to Earth, they have to make their way through the atmosphere and can be damaged and changed in the process. They also mean that researchers are able to use all of the Earth’s latest technology to study the sample. Other pieces of distant worlds have of course been studied by spacecraft and landers, but they are only able to do so with the limited instruments they take to those planets. Another advantage of sample return missions over studying the objects at their home is that scientists can look back at those samples with new sensors and equipment invented long after the sample was actually taken. Many space missions continue for years – Curiosity is still examining Mars after arriving there in 2012, and the Voyager probes are still providing information almost 50 years after they were launched – but they are only able to do so with the technology that was available when they set off. The analysis done in sample return missions really begins when the spacecraft arrives at its target: then, it starts looking at the context of the sample, gathering information about the world from which it came that should prove useful to scientists later. Osiris-Rex arrived at Bennu in 2018, and spent two years mapping the asteroid before it set off back home with its delivery. All of that information in addition to the samples could help answer a variety of questions about our planet, scientists hope. “The asteroids in our solar system contain the raw building blocks from which the Earth was made, so working out their composition will tell us a lot of how our planet formed,” said Boris Gansicke from the department of physics at the University of Warwick. “There are many open questions, for instance, where did the water that we have on Earth come from? And where did the ingredients that made life possible to develop come from? “To answer those questions, ie measure the composition of an asteroid, you need to get your ‘hands’ on them (or in this case the arm of a space mission), and this is what Osiris-Rex achieved. “In a nutshell, it’s similar to sitting in front of a delicious dinner and wanting to have the list of ingredients.” Sample return missions are almost as old as space travel itself, and the first of them were the early Apollo missions, which brought back pieces of the Moon. Those continue to be useful to scientists. Since then, as human travel into space has declined, most of the work has been done by robots. In the early 1970s, the Soviet Union’s Luna missions gathered pieces of the Moon and brought them back, and in 2020 Japan’s Hayabusa2 mission brought back pieces of the asteroid Ryugu. Scientists have high hopes for future missions: perhaps the most discussed is a mission to Mars, which would bring back the first ever pieces of that planet. Engineers have suggested that for decades, and a number of plans have been formed, but none are likely to launch any time soon.

Scientists have spotted a shocking number of galaxies like our own in the early universe. The finding will prompt us to entirely rethink our understanding of how the universe formed the structures that surround us. Looking deep into space, scientists found that the galaxies we see in the early universe are much more like our own Milky Way than was thought possible. A team of international researchers including those at The University of Manchester and University of Victoria in Canada, used the James Webb Space Telescope (JWST) to discover that galaxies like the Milky Way are 10 times more common than what was believed based on previous observations with the Hubble Space Telescope. Many of these galaxies formed some 10 billion years ago or longer, going far back into the history of the universe. The Milky Way is a typical disk galaxy, with a shape similar to a pancake or compact disc, rotating about its centre and often containing spiral arms. These galaxies might be the kind where life can develop given the nature of their formation history, experts suggest. Astronomers previously considered these types of galaxies too fragile to exist in the early universe when galaxy mergers were more common, destroying what was thought to be their delicate shapes. Christopher Conselice, professor of extragalactic astronomy at The University of Manchester, said: “Using the Hubble Space Telescope we thought that disc galaxies were almost non-existent until the universe was about six billion years old, these new JWST results push the time these Milky Way-like galaxies form to almost the beginning of the universe.” He added: “These JWST results show that disc galaxies like our own Milky Way, are the most common type of galaxy in the universe. “This implies that most stars exist and form within these galaxies which is changing our complete understanding of how galaxy formation occurs. “These results also suggest important questions about dark matter in the early universe which we know very little about.” “Based on our results, astronomers must rethink our understanding of the formation of the first galaxies and how galaxy evolution occurred over the past 10 billion years.” The researchers say their findings, published in the Astrophysical Journal, completely overturn the existing understanding of how scientists think the universe evolves, and the scientists say new ideas need to be considered. Lead author Leonardo Ferreira, from the University of Victoria, said: “For over 30 years it was thought that these disc galaxies were rare in the early universe due to the common violent encounters that galaxies undergo. “The fact that JWST finds so many is another sign of the power of this instrument and that the structures of galaxies form earlier in the universe, much earlier in fact, than anyone had anticipated.” The improved technology of JWST allows astronomers to see the true structure of these galaxies for the first time.

Ancient clay tablets unearthed from ancient ruins in Turkey by archaeologists have revealed a language lost to the passages of time. The new language was discovered in the ancient capital of the Hittite Empire at Hattusa (known as Boğazköy-Hattusha). The well-preserved tablets are among many incredible artworks found at the site - a UNESCO World Heritage Site. Over the past four decades, researchers have dusted off nearly 30,000 unique tablets - with most written in Hittite. New research, however, shows that some of the tablet haul shows that they are written in a language previously unknown to modern man. Of course, the meaning and words of this language have not been deciphered, but it appears from early inspection to branch off from languages used within the Hittite Empire - and is being referred to as Kalašma. Interestingly though, researchers from the Istanbul Department of the German Archaeological Institute have noted that the new language is found within a recitation in a 'cultic ritual text'. While that's usually the basis of a middling horror movie, we're certain that there's nothing to worry about - it stems from an ancient Hittite practice. Professor Daniel Schwemer explains that the discovery wasn't unexpected. "The Hittites were uniquely interested in recording rituals in foreign languages," he said. These ritual texts provide insight into little-known languages, and thanks to this discovery, one more has been added to the list.

India’s Chandrayaan-3 lander only touched down on the Moon a month ago, but already it's made some major contributions to science. The spacecraft arrived on the satellite's unexplored south pole on 23 August, securing India's place as the first country to achieve this ambitious feat. Its rover, named Pragyan (or "wisdom" in Sanskrit) then embarked on an exploration of the rocky terrain, equipped with two instruments for conducting chemical experiments. And now, India's space agency, the ISRO, has published the ground-breaking data collected by the bold robot. Pragyan's findings offered a new, detailed insight into what makes up the lunar soil. And whilst scientists were unsurprised by the presence of iron, titanium, aluminium and calcium in the rocks, they were stunned to note a much higher concentration of sulphur than expected. The discovery is significant for a number of reasons. Most significantly, perhaps, because the sulphur could be used to help create a human base on the Moon. As Jeffrey Gillis-Davis, a planetary scientist, pointed out in a piece for Science Alert: "Astronauts and robots could travel from the south pole base to collect, process, store and use naturally occurring materials like sulfur on the Moon – a concept called in-situ resource utilization. "In-situ resource utilization means fewer trips back to Earth to get supplies and more time and energy spent exploring. Using sulfur as a resource, astronauts could build solar cells and batteries that use sulfur, mix up sulfur-based fertilizer and make sulfur-based concrete for construction." Gillis-Davis went on to explain that sulfur-based concrete has a number of advantages over the more common variety used in building, pointing out that it "hardens and becomes strong within hours rather than weeks, and it's more resistant to wear". "It also doesn't require water in the mixture, so astronauts could save their valuable water for drinking, crafting breathable oxygen and making rocket fuel," he added. The presence of sulphur near the Moon's south pole also suggests that highland soils at the lunar poles could have very different compositions to highland soils at the lunar equatorial regions. This would have key implications for our understanding of how the Moon works as a geological system, given that sulfur mainly comes from volcanic activity. Still, there's plenty of work to be done. And while this is all just one small step in Chandrayaan-3's mission, it could mean a great leap in how we view our dear celestial companion.

Scientists have found that one of the key pillars of theory around how life works – that it depends on carbon – may not be the case on other planets. Here on Earth, life depends on organic compounds which are composed of carbon, and often involve other elements such as sulphur, oxygen, hydrogen, nitrogen and phosphorus. With organic compounds, life is partly sustained by chemical interactions called autocatalysis, which are self-sustaining. That means they produce molecules which then enable the reaction to happen again, and do not need any outside influence to keep going on. In the new study, scientists looked for autocatalysis in non-organic compounds. The theory is that if autocatalysis helps drive a process called abiogenesis – the origin process for life – then this origin process could also come from non-organic matter. Betül Kaçar, an astrobiologist, bacteriologist and evolutionary biologist at the University of Wisconsin-Madison, told news outlet Space.com: “It's important to explore these possibilities so that we have an idea of what all forms of life can look like, not just Earth life.” "One of the major reasons that origin-of-life researchers care about autocatalysis is because reproduction — a key feature of life — is an example of autocatalysis. “Life catalyses the formation of more life. One cell produces two cells, which can become four and so on. “As the number of cells multiply, the number and diversity of possible interactions multiplies accordingly.” The scientists searched in a huge trove of existing scientific documents for examples of autocatalysis, and found 270 different cycles of the reactions. Most of the 270 examples did not feature organic compounds, but rather elements which are rare in life forms such as mercury, or the radioactive metal thorium. “It was thought that these sorts of reactions are very rare,” Kaçar said in a statement. “We are showing that it's actually far from rare. You just need to look in the right place.” Now, it means scientists can test these cycles to get a better understanding of how autocatalysis can work. “The cycles presented here are an array of basic recipes that can be mixed and matched in ways that haven't been tried before on our planet,” said study author Zhen Peng, also an evolutionary biologist at the University of Wisconsin-Madison. “They might lead to the discovery of completely new examples of complex chemistry that work in conditions where carbon- or even silicon-based cycles are too either combusted or frozen out.” The scientists published their findings in the Journal of the American Chemical Society.

If you thought Australia’s spiders were scary, wait until you see the prehistoric version. Scientists have found a fossilised giant trapdoor spider in New South Wales, only the fourth specimen of its kind to be found in Australia. The creature would have roamed and hunted in the surrounding areas which were once a lush rainforest, researchers said in a recently filed report. Last year, scientists unearthed fossils of the rainforest area from millions of years ago, teeming with specimens including plants, trapdoor spiders, giant cicadas and wasps. Now the area is a grassland region known as McGraths Flat. Researchers have named the spider fossil ‘Megamonodontium mccluskyi’. It would have lived in the Miocene period 11m to 16m years ago. “Only four spider fossils have ever been found throughout the whole continent, which has made it difficult for scientists to understand their evolutionary history,” said palaeontologist Matthew McCurry of the University of New South Wales and the Australian Museum. “That is why this discovery is so significant, it reveals new information about the extinction of spiders and fills a gap in our understanding of the past. “The closest living relative of this fossil now lives in wet forests in Singapore through to Papua New Guinea. “This suggests that the group once occupied similar environments in mainland Australia but have subsequently gone extinct as Australia became more arid.” The spider was found among many other Miocene fossils. In some of them, the fossils were so well preserved that subcellular structures could be made out. “Scanning electron microscopy allowed us to study minute details of the claws and setae on the spider's pedipalps, legs and the main body,” said virologist Michael Frese of the University of Canberra. The details meant scientists could confidently place it near the modern Monodontium, or trapdoor spider. However, it is five times larger than its modern day relatives. Megamonodontium mccluskyi's body is 23.31 millimetres long – that is just over an inch. The discovery of the species also tells us something of the past climate of Australia, the report added. The fact that it was found in a layer of rainforest sediment means the region was once much wetter than it is now. That could, in turn, help scientists understand how a warming climate has already altered the country’s life forms – and how it might change them again. "Not only is it the largest fossilized spider to be found in Australia but it is the first fossil of the family Barychelidae that has been found worldwide," said arachnologist Robert Raven of Queensland Museum. "There are around 300 species of brush-footed trapdoor spiders alive today, but they don't seem to become fossils very often. "This could be because they spend so much time inside burrows and so aren't in the right environment to be fossilized." The findings were published in the Zoological Journal of the Linnean Society.
