A Faint Stellar Stream Outside the Milky Way Is Revealing Hidden Dark Matter — Curiosmos
1+ day, 21+ hour ago (516+ words) An ancient star cluster is slowly coming apart in a galaxy 115 million light-years away. The thin trail it left behind is giving astronomers a new way to study dark matter beyond the Milky Way. Astronomers have identified the first stellar…...
Astronomers detect ancient hydrogen signal, opening new way to map Universe
5+ day, 2+ hour ago (646+ words) Wednesday September 09, 2026 Astronomers have directly detected an extremely faint radio signal from hydrogen gas billions of light-years away, marking an important step toward using hydrogen to map the large-scale structure of the Universe. An international research team led by scientists…...
Galaxy Proto-supercluster Sets Distance Record
5+ day, 14+ hour ago (719+ words) Galaxy clusters are the most massive gravitationally bound structures in the Universe. These colossal groupings of hundreds to thousands of galaxies span millions of light-years. They are held together by large concentrations of dark matter, which serves as the building…...
Extremely Massive Galaxy Proto-Supercluster Smashes Distance Records - The ancestor to a ‘cluster-of-clusters’ of galaxies has a mass 5000 times that of the Milky Way and lies in one of the densest regions of the cosmic web ever observed
5+ day, 15+ hour ago (864+ words) Galaxy clusters are the most massive gravitationally bound structures in the Universe. These colossal groupings of hundreds to thousands of galaxies span millions of light-years. They are held together by large concentrations of dark matter, which serves as the building…...
Black Holes May Not Be as Empty as We Thought, Scientists Discover a New Way to Search for Hidden Matter
5+ day, 14+ hour ago (762+ words) Scientists have uncovered a new approach to reading black hole signals, but the strange possibility behind the pattern remains one of the biggest mysteries. Black holes may hide structures that cannot be seen directly but could leave traces in gravitational…...
Every galaxy in our neighborhood, including our own, is being pulled toward a single point in space hidden directly behind the crowded disk of the Milky Way, and when astronomers finally looked through the dust, they found a large, previously hidden cluster of thousands of galaxies sitting almost exactly where the pull was coming from
1+ week, 5+ day ago (216+ words) Astronomers spent decades chasing an invisible force pulling our galaxy through space, only to discover it was hidden in plain sight behind cosmic dust. Published September 2, 2026 · How we edit In 1986, a small team of astronomers noticed something that did not…...
???? 129 galaxies examined in search of an extraterrestrial civilization - News
1+ week, 6+ day ago (362+ words) Sep 1, 2026, 07:00 AM FR · ES · DE · PT A team searched 129 galaxies for the heat that could be produced by a civilization using a large share of the energy from its stars. The idea relies on a simple physical consequence. Technology that…...
Hypothetical 'dark stars' could explain gravitational-wave hum, study finds
2+ week, 6+ day ago (474+ words) Scientists made the first direct detection of gravitational waves in 2015. That high-frequency burst came from colliding stellar-mass black holes. That signal matched what Einstein’s general relativity had predicted decades earlier. Since then, researchers have turned to a different technique to…...
Breakthrough in a Bizarre Galaxy Could Help Unlock the Mystery of Dark Matter
3+ week, 18+ hour ago (655+ words) The first globular cluster stellar stream found beyond the Milky Way shows that these faint structures can be used to study dark matter in other galaxies. A faint ribbon of stars stretching across a galaxy can preserve a record of…...
