We’ve reported on all kinds of wacky ideas for capturing and deorbiting space debris safely. From electric tethers to lasers, engineers and scientists have been trying everything they can think of to deal with the ever-increasing orbital debris problem. But one simple design keeps popping up over and over again—a net. A new paper from […] With new technologies come new opportunities. And that is especially true in astronomy—with every new advanced telescope, we have the potential to see (or in some cases, listen) farther and more clearly than ever before. That is certainly the case for the new Square Kilometer Array (SKA), which is currently undergoing a multiyear rollout phase. […] The Canadian astronaut who was part of the historic Artemis II crew that successfully voyaged around the moon earlier this year is retiring from the nation’s space agency, officials said Monday. Go to Source Scale in the universe is hard to understand from a purely human perspective. Many times, the math just doesn’t sit well with our brains, which evolved to capture and process data about the world around us rather than grok the complexities of stellar dynamics and galaxy mergers. But every once in a while, astronomers find […] A new Southwest Research Institute-led study compared eight AI-generated lunar crater catalogs, discovering that many of their published performance metrics drop sharply when the databases are evaluated using the same scientific standards humans are held to. Crater catalogs provide a comprehensive record of impact craters on planetary surfaces. They log the precise location, dimensions and […] Rare images taken by a Japanese space probe during a flyby of a near-Earth asteroid have revealed that the space rock resembled a snowman, scientists said Monday. Go to Source In the course of studying planets beyond our solar system (6,316 confirmed exoplanets and counting), scientists have discovered some very interesting systems. Consider TOI-201, a compact system populated by three bodies, including a brown dwarf, orbiting on the same plane. The system was recently observed by an international team led by the European Southern Observatory […] In new images from NASA’s James Webb Space Telescope to celebrate its fourth science anniversary, a familiar galaxy transforms into something far richer and far more complex than ever seen before. Webb’s unprecedented sensitivity across near- and mid-infrared wavelengths cuts through the thick lanes of dust that obscure Centaurus A’s center in visible light, showing […] When massive stars die, they unleash some of the most powerful explosions in the universe. Yet not all supernovae are created equal. Some continue to shine brightly for months or even years as their expanding debris crashes into dense clouds of gas surrounding the star. These spectacular events, known as interacting supernovae, have puzzled astronomers […] Astronomers have used the European Southern Observatory’s Very Large Telescope (ESO’s VLT) to study the composition of 3I/ATLAS, the brightest interstellar object ever seen, in detail. By measuring specific chemical fingerprints—the first observations of this kind for a comet that formed outside the solar system—they found that 3I/ATLAS likely originated in the outskirts of an […] China’s Tianwen-2 space probe, which is set to bring back samples from an asteroid for research, has reached its target after traveling 1 billion kilometers (620 million miles) over more than a year, the Chinese space agency said Monday. Go to Source The European Space Agency’s Euclid space telescope has discovered 31 of the most ancient quasars ever found. Two of these giant and dazzling galaxy cores, powered by gargantuan black holes, are the earliest quasars yet observed in cosmic history. They shone with the light of a trillion suns when the universe was 670 million years […] Where would you go to watch a star being born? Probably not the heart of the Milky Way, which is about the most violent neighborhood our galaxy has to offer, a maelstrom of gas churning so fast and so chaotically that you would think nothing could ever settle there long enough to collapse into a […] Comets have played an interesting role in the history of astronomy. Since antiquity, many cultures saw them as omens or spirits, portending good or bad news for kings, queens and emperors. Over the past few hundred years, however, astronomers have studied them intently to understand the science behind these visitors to the inner solar system. […] Dust devils are a regular feature on Mars. Just like those found on Earth, these mini whirlwinds form when parts of Mars are warmed by the sun, causing air above the surface to swirl upward and carry dust with it. But in Mars’ lower gravity (38% that of Earth), these devils grow much larger, reaching […] |
