When a mudflat crumbles on Earth, or an ice sheet splinters on one of Jupiter’s moons (Europa), or an ancient lakebed breaks on Mars, do these fractures follow a hidden geometric script? Could similar patterns on another planet hint that water once existed there—and possibly sustained life? Go to Source Sometimes scientists must dig and work and sweat to make scientific discoveries. And sometimes a robot rolls over a rock that turns out to be a revelation. Go to Source With a sun more than 4.5 billion years old, our solar system is considered “middle-aged,” and the pictures of what it might have looked like in its infancy are lost to time. Taking advantage of a sophisticated adaptive optics instrument, a team of astronomers at the University of Arizona made observations that reveal unprecedented details […] The first commercial mission of Europe’s new heavy-lift rocket Ariane 6 has been rescheduled for Thursday, French company Arianespace announced, after an “anomaly” forced a last-minute postponement. Go to Source Elon Musk’s SpaceX is now aiming for Wednesday to conduct the next test flight of its massive Starship rocket, following a last-minute cancellation on Monday. Go to Source After tracking a puzzling X-ray signal from a dying star for decades, astronomers may have finally explained its source: The old star might have destroyed a nearby planet. Go to Source NASA’s two stuck astronauts are just a few weeks away from finally returning to Earth after nine months in space. Go to Source If there were such a thing as a photo album of the universe, it might include snapshots of pancake-like disks of gas and dust, swirling around newly formed stars across the Milky Way. Known as planet-forming disks, they are believed to be a short-lived feature around most, if not all, young stars, providing the raw […] A University of Alaska Fairbanks scientist is participating in a U.S. government effort to design a satellite and instruments capable of detecting space debris as small as 1 centimeter, less than one-half inch. Go to Source Led by Rocket Lab of Long Beach, California, and their partners at the Massachusetts Institute of Technology in Cambridge, Rocket Lab’s Venus mission will be the first private mission to the planet. Go to Source Located 2.5 million light-years away, the majestic Andromeda galaxy appears to the naked eye as a faint, spindle-shaped object roughly the angular size of the full moon. What backyard observers don’t see is a swarm of nearly three dozen small satellite galaxies circling the Andromeda galaxy, like bees around a hive. Go to Source […] Pop star Katy Perry is set to “shoot across the sky” this spring when she lifts off as part of a six-member, all-female crew on Blue Origin’s next space flight, the company announced Thursday. Go to Source Living organisms need nitrogen as a central building block for protein formation, for example. However, although our atmosphere contains plenty of nitrogen, neither humans nor the vast majority of plants can absorb it directly from the air. Go to Source Astronauts often experience immune dysfunction, skin rashes, and other inflammatory conditions while traveling in space. A new study published in the journal Cell suggests that these issues could be due to the excessively sterile nature of spacecraft. Go to Source Using the James Webb Space Telescope (JWST), an international team of astronomers has explored the atmosphere of a nearby brown dwarf binary designated WISE J045853.90+643451.9. As a result, they detected hydrogen cyanide and acetylene in the atmosphere of this binary, marking the first time these two species have been identified in the atmosphere of a […] |
