Hubble Telescope sees ‘weird things’ in closest-ever look at a quasar from monster black hole (Image Credit: Space.com) The Hubble Space Telescope has stared deeper into a quasar than ever before, discovering “weird” features in its vicinity. Quasars are the superbright centers of active galaxies, and they’re powered by feeding supermassive black […]
SpaceX is gearing up for the seventh test flight of its Starship megarocket, which could take place in just a month or so. The company conducted a static-fire test with Flight 7’s Super Heavy first-stage booster today (Dec. 9), briefly igniting its 33 Raptor engines at a pad at SpaceX‘s Starbase facility in South Texas. […]
100th woman in space, Emily Calandrelli, stands up to ‘small men’ on the internet: ‘I should have expected this.’ (Image Credit: Space.com) Emily Calandrelli made history on Nov. 22, 2024, when she became the 100th woman to go to space. But thanks to “small men on the internet,” the monumental milestone was […]
Examining how Mars’ infamous dust storms can engulf the entire planet (Image Credit: Phys.org) Credit: Pixabay/CC0 Public Domain In a new study, planetary scientists at the University of Colorado Boulder have begun to unravel the factors that kick off major dust storms on Mars—weather events that sometimes engulf the entire planet in […]
More than 10,000 supernovae counted in stellar census (Image Credit: Phys.org) SN 1987a, a Type II supernova remnant first observed in 1987, is visible in this image taken by the Hubble Space Telescope in 2017. The bright ring around the exploded star is material it had ejected approximately 20,000 years before its […]
Black hole debate settled? Stellar-mass black holes found at heart of Milky Way’s largest star cluster (Image Credit: Phys.org) Credit: University of Surrey Could a decades-long debate about the mysterious movements of stars in Omega Centauri, the largest star cluster in the Milky Way, finally be resolved? Omega Centauri is a massive […]
Webb telescope’s largest study of universe expansion confirms challenge to cosmic theory (Image Credit: Phys.org) Credit: CC0 Public Domain New observations from the James Webb Space Telescope suggest that a new feature in the universe—not a flaw in telescope measurements—may be behind the decade-long mystery of why the universe is expanding faster […]
