With plans to launch the massive Starship from Florida next year, SpaceX defended its commitment to airspace safety after a Wall Street Journal article claimed an explosive mission in early 2025 was a greater danger to some flights than previously reported. Go to Source The James Webb Space Telescope (JWST) was involved in yet another first discovery recently available in pre-print form on arXiv from Cicero Lu at the Gemini Observatory and his co-authors. This time, humanity’s most advanced space telescope found UV-fluorescent carbon monoxide in a protoplanetary debris disk for the first time ever. It also discovered some […] With the International Space Station (ISS) set to retire in 2030, several nations and commercial space companies have plans to deploy their own successor stations. This includes China, which plans to double the size of its Tiangong space station in the coming years, and the Indian Space Research Organization’s (ISRO) proposed Bharatiya Antariksh Station (BAS), […] Astronomers using NASA’s Hubble Space Telescope have imaged the largest protoplanetary disk ever observed circling a young star. For the first time in visible light, Hubble has revealed the disk is unexpectedly chaotic and turbulent, with wisps of material stretching much farther above and below the disk than astronomers have seen in any similar system. […] More than a billion years ago, in a shallow basin across what is now northern Ontario, a subtropical lake much like modern-day Death Valley evaporated under the sun’s gentle heat, leaving behind crystals of halite—rock salt. Go to Source The shape of the universe is not something we often think about. My colleagues and I have published a new study that suggests it could be asymmetric or lopsided, meaning not the same in every direction. Go to Source NASA’s James Webb Space Telescope captured two nearby dwarf galaxies interacting with each other in this image released on Dec. 2, 2025. Go to Source Engineers need good data to build lasting things. Even the designers of the Great Pyramids knew the limestone they used to build these massive structures would be steady when stacked on top of one another, even if they didn’t have tables of the compressive strength of those stones. Go to Source A sideways spiral galaxy shines in this NASA/ESA Hubble Space Telescope image. Located about 60 million light-years away in the constellation Virgo (the Maiden), NGC 4388 is a resident of the Virgo galaxy cluster. This enormous cluster of galaxies contains more than a thousand members and is the nearest large galaxy cluster to the Milky […] Black holes are notorious for gobbling up everything that comes their way, but astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered that even supermassive black holes can be picky eaters, and this can have a significant impact on their growth. Go to Source Professor Woong-bae Zee of the College of Liberal Studies at Sejong University has revealed that a galaxy does not possess only a single evolutionary pathway; instead, depending on the nature of its neighboring galaxy, it can exhibit two entirely different “faces of evolution.” The work is published in The Astrophysical Journal. Go to Source […] Researchers from Yunnan University, the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences, and the National Astronomical Observatory of Japan have unveiled new insights into the fragmentation mechanisms of high-mass star-forming regions. Go to Source Among the more puzzling cosmic phenomena discovered over the past few decades are brief and very bright flashes of blue and ultraviolet light that gradually fade away, leaving behind faint X-ray and radio emissions. With slightly more than a dozen discovered so far, astronomers have debated whether they are produced by an unusual type of […] When the most massive stars reach the ends of their lives, they blow up in spectacular supernova explosions, which seed the universe with heavy elements such as carbon and iron. Another type of explosion—the kilonova—occurs when a pair of dense dead stars, called neutron stars, smash together, forging even heavier elements such as gold and […] After less than a year in orbit, the Southwest Research Institute-built PUNCH spacecraft have made major accomplishments, imaging the sun in context while tracking comets and enormous space weather events as they traveled through the inner solar system. SwRI’s Dr. Craig DeForest discussed the achievements of NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) […] |
