Astronomers have employed the upgraded Giant Metrewave Radio Telescope (uGMRT) and the MeerKAT radio telescope to observe a galaxy cluster known as RXCJ0232–4420. Results of the new observations, published April 29 on the arXiv pre-print server, deliver important insights into the nature of this cluster. Go to Source The comet that rambled past us from another star last year likely originated in a cold, isolated corner of the galaxy that had yet to gel into its own solar system, astronomers reported Thursday. Go to Source Ganymede is not only Jupiter’s largest moon, but also the largest in our solar system and one of the few that hosts a massive ice ocean. Adding to this planet-like moon’s uniqueness is the fact that among the hundreds of moons in our solar system, Ganymede is the only one that generates its own magnetic […] Astronomers using the James Webb Space Telescope have made a surprising discovery about a galaxy long, long ago and far, far away: It isn’t rotating. That’s something only seen in the most massive, mature galaxies that are closer to us in space and time, said Ben Forrest, a research scientist in the Department of Physics […] For the first time, scientists have measured the instantaneous mind-blowing power of jets blasting from a black hole. Go to Source NASA’s Psyche spacecraft will get a boost from Mars on Friday, May 15, passing just 2,800 miles (4,500 kilometers) from the planet’s surface at some 12,333 mph (19,848 kph). The spacecraft will harness the planet’s gravitational pull to speed up and adjust its trajectory toward the metal-rich asteroid Psyche, one of the more unusual objects […] One night last fall, University of Cincinnati astrophysics graduate Paul Smith waited anxiously for data to start rolling across his computer screen from the James Webb Space Telescope a million miles from Earth. Go to Source The European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) have signed a Memorandum of Cooperation to deepen collaboration in planetary defense, alongside a dedicated agreement for collaboration on the Rapid Apophis Mission for Space Safety (Ramses) to the near-Earth asteroid Apophis. Go to Source A new study, published in Science Advances, has refined some important details about the moon’s largest and oldest impact crater, which stretches more than 1,200 miles (2,000 km) on the far side of the moon. The new details can help guide some of the planning for NASA’s upcoming Artemis mission to the moon, which is […] Researchers at National Jewish Health have published new findings demonstrating that short-duration spaceflight may not significantly impact lower extremity joint structures, while also identifying a promising, noninvasive tool to monitor astronaut musculoskeletal health on future long-duration missions. Go to Source A spiral galaxy’s brilliant heart outshines everything within sight in a new picture from NASA’s Webb Space Telescope. Go to Source The mysterious origin of an impressive cloud disturbance on Venus has now been revealed by a team including the University of Tokyo. Researchers used numerical models to show that an enormous 6,000-kilometer-wide atmospheric wave front, which circumnavigates the planet for days at a time, is caused by a large “hydraulic jump.” This is when a […] NASA’s home for experimental flight is welcoming more flyers to its already high-performing fleet as it continues to support science and aeronautics test missions—continuing the legacy of pioneers like Neil Armstrong. Go to Source New research reveals that Dante Alighieri’s Inferno wasn’t just a masterpiece of literature: it was a gedankenexperiment in impact physics. From multi-ring craters to shockwaves that reshaped the globe, discover how a 14th-century poet modeled a planetary impact 500 years before the birth of modern meteoritics. Go to Source There may be an ultraheavy explanation for the mystery surrounding the origins of the highest-energy particles ever observed. Ultrahigh-energy cosmic rays are particles from space that strike Earth with energies far beyond those reachable by human-made particle accelerators. One of the most extreme events ever recorded is the “Amaterasu particle,” detected by the Telescope Array […] |
