New study maps ripples and hidden structures in southern Milky Way
Los Angeles CA (SPX) Sep 07, 2025 Astronomers have produced the most detailed 3D map yet of the Milky Way's cold gas clouds, revealing large-scale ripples in the Galaxy's midplane and identifying a new structure at the far end of the central bar. The work comes from the Three-millimeter Ultimate Mopra Milky Way Survey (ThrUMMS), led by Peter Barnes of the Space Science Institute. Spiral galaxies like the Milky Way are generally flat, but the team found that the Galaxy's cold gas distribution is warped into a wave-like pattern. The ... read more |

First-of-its-kind supernova reveals innerworkings of a dying star
Evanston IL (SPX) Aug 22, 2025 An international team of scientists, led by Northwestern University astrophysicists, has detected a never-before-seen type of exploding star, or supernova, that is rich with silicon, sulfur and argon. When massive stars explode, astrophysicists typically find strong signatures of light elements, such as hydrogen and helium. But the newly discovered supernova, dubbed SN2021yfj, displayed a startling different chemical signature. Astronomers long have theorized that massive stars have a layere ... read more 
Astronomers capture a record 130-year evolution of a dying starManchester UK (SPX) Aug 22, 2025 For the first time, scientists have directly tracked the slow transformation of a dying star over more than a century - revealing it is heating up faster than any other typical star ever observed. ... more |

Early detection methods refine study of stellar explosionsParis, France (SPX) Aug 22, 2025 Supernovae are sudden stellar explosions that flare brightly in the sky, making them difficult to capture in their earliest moments. With modern wide-field, high-cadence sky surveys, astronomers can ... more 
Supernovae: How to spot them at record speedParis, France (SPX) Aug 22, 2025 Supernovae appear to our eyes-and to astronomical instruments-as brilliant flashes that flare up in the sky without warning, in places where nothing was visible just moments before. The flash is cau ... more 
Using exoplanets to study dark matterRiverside CA (SPX) Aug 22, 2025 More than 5,000 planets have been discovered beyond our solar system, allowing scientists to explore planetary evolution and consider the possibility of extraterrestrial life. Now, a UC Riverside ... more 
Gas streamers reveal how massive young stars gain their massTokyo, Japan (SPX) Aug 21, 2025 A research team led by Kyoto University and the University of Tokyo has identified gas streamers as a key mechanism feeding high-mass young stars, challenging the long-held assumption that large acc ... more
