Astronomers find 'Tatooine' planet orbiting two stars
Astronomers believe they've discovered a "Tatooine"-like planet orbiting two stars in a galaxy far, far away.
The planet is orbiting two brown dwarfs, which are also known as failed stars.
It's about 120 light years away from our solar system.
If you're a "Star Wars" fan, you might be excited to learn scientists may have discovered a planet that's orbiting two stars, much like the fictional planet of "Tatooine."

The planet is located about 120 light years away from our solar system, according to astronomers at the University of Birmingham, U.K.
A light year is nearly 6 trillion miles, in case you were trying to convert the distance.
The exoplanet appears to take an unusual path around two brown dwarf stars, circling at a right angle.
Brown dwarfs are sometimes called failed stars because they're lighter than stars but are heavier than gas giant planets.
The pair of brown dwarfs were first discovered years ago and scientists noticed that the twins eclipse each other so one is always partly blocked when seen from Earth.
In a new analysis, researchers found that the brown dwarfs' motion was changing — a quirk that's less likely to happen if they circled each other on their own. The research was published in the journal Science Advances.
The planet was discovered using the European Southern Observatory's Very Large Telescope (LVT).
Yes, there are actually several dozen planets that are orbiting two stars throughout the cosmos, scientists said.
But the new planet's odd orbit sets it apart. Though it hasn't been directly spied on, scientists say more research is needed to be sure it's out there and figure out its mass and orbit.
What they're saying
"I wouldn't bet my life that the planet exists yet," said Simon Albrecht, an astrophysicist with Aarhus University who had no role in the new study.
Probing these wacky celestial bodies can help us understand how conditions beyond our solar system may yield planets vastly different from our own, said study author Thomas Baycroft with the University of Birmingham.
Planets circling twin stars "existed in sci-fi for decades before we knew that they could even really exist in reality," he said.

Yellowstone is hiding more than 80,000 earthquakes below its surface
Researchers at the University of Western Ontario have uncovered over 86,000 earthquakes moving in chaotic swarms through rough, young fault lines beneath Yellowstone. The findings are significantly higher than the previously known number of earthquakes in the area. The study appears in the journal Science Advances. 'With these new insights, we're getting closer to decoding Earth's volcanic heartbeat and improving how we predict and manage volcanic and geothermal hazards,' the authors write in a statement. Researchers used a machine learning algorithm to process and identify earthquake signals within 15 years of seismic data from the Yellowstone caldera, which was formed by a volcanic eruption more than 630,000 years ago. Previously, researchers manually inspected earthquake data—a process that was both expensive and time-consuming. By automating the detection and classification of seismic events, machine learning allowed the Western team to uncover many more earthquakes in the dataset, revealing ten times more seismic activity than previously known. That brings the historical catalogue for the Yellowstone caldera up to 86,276 earthquakes between 2008 and 2022 and paints a much clearer picture of what's going on beneath the surface, researchers say. "To a large extent, there is no systematic understanding of how one earthquake triggers another in a swarm. We can only indirectly measure space and time between events," Western engineering professor Bing Li, one of the study's authors, says. "But now, we have a far more robust catalogue of seismic activity under the Yellowstone caldera, and we can apply statistical methods that help us quantify and find new swarms that we haven't seen before, study them, and see what we can learn from them."

Our Neanderthal Cousins Were Big Maggot Eaters, Scientists Argue
Modern humanity's most famous cousins, the Neanderthals, may have had a clever, if unappealing, dietary trick for survival: maggots. Research out today posits these creepy crawly fly larvae provided Neanderthals an ample source of essential nitrogen and fat. Scientists at Purdue University, the University of Michigan, and others conducted the study, published Friday in Science Advances. Using both experimental and historical data, they showed that maggot-infused meat is rich in fat and nitrogen and that similar human populations have commonly included such foods in their diets. The team argues that maggots are the most reasonable explanation for why Neanderthals had very high levels of nitrogen in their system. 'Fly larvae are a fat-rich, nutrient dense, ubiquitous, and easily procured insect resource, and both Neanderthals and anatomically modern humans, much like recent foragers, would benefit from taking full advantage of them,' lead author Melanie Beasley, a paleoanthropologist at Purdue, told Gizmodo. Nitrogen is a much-needed nutrient; among other things, it's used to help create amino acids, the building blocks of proteins. Speaking of protein, dietary nitrogen is most abundantly found in animal meat (though certain leafy vegetables and legumes are also high in it). The excavated remains of Neanderthals are known to have high levels of nitrogen isotopes, indicating they had plenty of nitrogen in their diets. According to Beasley, most researchers have assumed this meant Neanderthals were hypercarnivores—predators at the top of the food chain that ate lots of freshly killed large animals, mammoths included. But in 2017, co-author John Speth put forth a different hypothesis: that Neanderthals were actually eating lots of stored and putrid meat filled with maggots. Both then and now, researchers note that some Indigenous groups in the Northern Hemisphere have regularly and intentionally eaten maggot-rich food—practically as a delicacy. In 1931, for instance, Knud Rasmussen, a polar explorer and anthropologist, wrote this anecdote about him and some members of an Inuit community coming across a cache of meat: 'The meat was green with age, and when we made a cut in it, it was like the bursting of a boil, so full of great white maggots was it. To my horror my companions scooped out handfuls of the crawling things and ate them with evident relish.' Beasley heard about Speth's argument and said she could help him test it out experimentally. At the time, she was pursuing a postdoctoral degree that involved studying muscle tissue decomposition in deceased people. This work also meant Beasley would spend much of her time around the maggots that feed on decaying tissue. Beasley and her colleagues documented the changing nitrogen levels in these samples of decaying tissue along with three different species of fly maggots. As the tissue decayed, levels of nitrogen inside changed modestly. The maggots themselves, however, were chock-full of nitrogen. Given the conditions back then, it would have been impossible for Neanderthals to avoid some maggots ending up in any animal meat they tried to store. Rather than a hindrance, though, these hominids probably made the most of the situation, using the maggots to turn their lean meat into a 'fat-rich, more complete food resource,' Beasley said. The researchers are still collecting more evidence to shore up their argument for maggot-eating Neanderthals, and they're also working to understand how the nutritional benefits of maggot-rich food change over time (exactly when is rotten meat too rotten, in other words?). However Neanderthals ate their meat, though, there are many people today still using insects and maggots to spice up their diet, the researchers point out. In Europe, for instance, there's casu marzu, a Sardinian sheep's milk cheese that's intentionally laced with cheese fly (Piophila casei) maggots. Much love to my Neanderthal brethren and casu marzu fans, but I think I'll still just stick to some classic sharp cheddar for my next cheese plate.

Fossils unearthed in Grand Canyon reveal new details of evolutionary explosion of life
Paleontologists have discovered remarkable fossils in the Grand Canyon that reveal fresh details about the emergence of complex life half a billion years ago. The newfound remains of fauna from the region suggest that it offered ideal conditions for life to flourish and diversify, in a 'Goldilocks zone' between harsh extremes elsewhere. This evolutionary opportunity produced a multitude of early animals, including oddballs with peculiar adaptations for survival, according to new research. During the Cambrian explosion, which played out in the coastal waters of Earth's oceans about 540 million years ago, most animal body types that exist today emerged in a relatively short time span, scientists believe. Back then, the Grand Canyon was closer to the equator, and the region was covered by a warm, shallow sea teeming with burgeoning life — aquatic creatures resembling modern-day shrimp, pill bugs and slugs — all developing new ways to exploit the abundant resources. Researchers turned to the Grand Canyon's layers of sedimentary rock to unlock secrets of this pivotal moment in the history of life, digging into the flaky, claylike shale of the Bright Angel Formation where most of the canyon's Cambrian-era fossils have been found. The study team expected to recover mostly the fossilized remains of hard-shelled invertebrates typical of the region. Instead, the team unearthed something unusual: rocks containing well-preserved internal fragments of tiny soft-bodied mollusks, crustaceans, and priapulids, also known as penis worms. 'With these kinds of fossils, we can better study their morphology, their appearance, and their lifestyle in much greater resolution, which is not possible with the shelly parts,' said Giovanni Mussini, the first author of the study published Wednesday in the journal Science Advances. 'It's a new kind of window on Cambrian life in the Grand Canyon.' Using high-powered microscopes, the team was able to investigate innovations such as miniature chains of teeth from rock-scraping mollusks and the hairy limbs and molars of filter-feeding crustaceans, providing a rare look into the biologically complex ways Cambrian animals adapted to capture and eat prey. For most of the planet's 4 billion-year history, simplicity reigned. Single-celled microbes remained stationary on the ocean floor, thriving on chemical compounds such as carbon dioxide and sulfur molecules to break down food. What changed? Scientists still debate what drove the Cambrian explosion, but the most popular theory is that oxygen in the Earth's atmosphere slowly began to increase about 550 million years ago, said Erik Sperling, an associate professor of Earth and planetary sciences at Stanford University. Oxygen provided a much more efficient way to metabolize food, giving animals more energy to mobilize and hunt for prey, suggested Sperling, who was not involved in the new study. 'The (emergence of) predators kicked off these escalatory arms races, and then we basically got the explosion of different ways of doing business,' Sperling said. During the Cambrian, the shallow sea covering the Grand Canyon was especially oxygen-rich thanks to its perfect, 'Goldilocks' depth, said Mussini, a doctoral student in Earth sciences at the University of Cambridge in the United Kingdom. Ranging from 40 to 50 meters (about 130 to 165 feet) in depth, the ecosystem was undisturbed by the shoreline's constant waves shifting around sediments, and sunlight was still able to reach photosynthesizing plants on the seafloor that could provide oxygen. The abundance of food and favorable environmental conditions meant that animals could take more evolutionary risks to stay ahead of their competition, Mussini said. 'In a more resource-starved environment, animals can't afford to make that sort of physiological investment,' Mussini said in a news release from the University of Cambridge. 'It's got certain parallels with economics: invest and take risks in times of abundance; save and be conservative in times of scarcity.' Many soft-bodied fossil finds before this one have come from regions with harsh environments such as Canada's Burgess Shale formation and China's Maotianshan Shales, noted Susannah Porter, a professor of Earth science at the University of California in Santa Barbara who was not involved in the study. 'It's not unlike if paleontologists far in the future only had great fossil records from Antarctica, where harsh cold environments forced people to adapt. … But then found great human fossils in New York City, where people flourished,' Porter explained. 'We have an opportunity to see different sorts of evolutionary pressures that aren't like, it's really cold, it's really hot, there's not a lot of water.' While some of the feeding mechanisms uncovered in the Grand Canyon fossils are still around today, others are much more alien. Among the most freakish: penis worms that turned their mouths inside out, revealing a throat lined with hairy teeth. The worms, also known as cactus worms, are mostly extinct today, but were widespread during the Cambrian. The fossilized worm found in the Grand Canyon represents a previously unknown species. Due to its relatively large size — about 3.9 inches (10 centimeters) — and distinct teeth, it was named Kraytdraco spectatus, after the fictional krayt dragon from the Star Wars universe, Mussini said. This particular penis worm appears to have had a gradient of hundreds of branching teeth used to sweep food into their extendable mouths. 'It's a bit hard to understand how exactly it was feeding,' Mussini said. 'But it was probably eating debris on the seafloor, scraping it away with some of the most robust teeth that it had, and then using these other, more delicate teeth to filter and retain it within this long, tube-like mouth.' Rows of tiny molars, sternal parts and comblike limbs that once belonged to crustaceans were also among the findings, which all date back 507 million to 502 million years. Similar to today's brine shrimp, the crustaceans used these fine-haired limbs to capture floating food from the water and bring it to the mouth, where molars would then grind down the particles, Mussini explained. Nestled among the molars, researchers even found a few unlucky plankton. Other creatures resembling their modern counterparts included sluglike mollusks. The fossils revealed chains of teeth that likely helped them scrape algae or bacteria from along the seafloor. 'For each of these animals, there's different components, but most of what we found directly relates to the way these animals were processing their food, which is one of the most exciting parts, because it tells us a lot about their lifestyle, and as a consequence, their ecological implications,' Mussini said.
