3+ day, 4+ hour ago   (477+ words) When two black holes find each other in the vastness of space, they can form a binary odd couple—and it’s more common than researchers expected. Scientists think most black holes are born when a star dies and its core…...

3+ day, 18+ hour ago   (900+ words) Little red dots should shine in X-rays if black holes power them. None did, until Chandra found one 11.8 billion light-years away that does. Astronomers have found a single object in the constellation Ursa Major that behaves like nothing else in…...

4+ day, 8+ hour ago   (373+ words) Using mathematical analysis of Einstein's equations, the research team proved the answer is no. When there are two or more black holes in such a configuration, the interaction forces between them cannot completely cancel each other out, and a static…...

4+ day, 18+ hour ago   (556+ words) A brilliant X-ray source is not automatically a black hole. Matter falling toward a neutron star can also become intensely luminous, and some neutron stars have surprised astronomers by producing far more radiation than expected. Identifying the object requires evidence…...

4+ day, 20+ hour ago   (157+ words) A few hundred million years after the Big Bang, the first stars ignited - literally the “let there be light” moment for the universe. Now known to astronomers as Population III, or Pop III, stars, these giants were very different from…...

5+ day, 2+ hour ago   (763+ words) An international research team has discovered COSMOS-z3.1-A, a protosupercluster located approximately 12 billion light-years from Earth with a mass roughly 5,000 times that of the Milky Way. It is the most distant and most massive protosupercluster ever identified. The team, led…...

5+ day, 7+ hour ago   (407+ words) International team including Korea Astronomy and Space Science Institute makes the discovery First detailed three-dimensional map of multiple protoclusters produced "Skeleton of the universe's largest structures was already forming when the cosmos was 2 billion years old" Researchers call it a…...

5+ day, 19+ hour ago   (480+ words) The team links this growth to the galaxy UGC 1176, located approximately 400,000 light-years away. Such close encounters can disturb cold gas in the outskirts of a galaxy and trigger star formation there. According to Ignacio Trujillo, a researcher at the Instituto…...

5+ day, 19+ hour ago   (374+ words) The spectrum added two more clues: broad, multi-peaked hydrogen emission combined with hydrogen absorption features, and tentative variability between two observations taken roughly a year apart. Black holes flicker as their feeding rates change. Stars don’t. The mechanism, once stated…...

5+ day, 20+ hour ago   (17+ words) A telescope worth ten billion dollars stared into the dawn of time and came back with freckles....
