Sep. 7, 2023 — Massive burst of X-rays detected by astronomers indicates material three times the mass of Earth burning up in a black hole. They observed a star like our own Sun being eaten away every time it ...
Aug. 31, 2023 — While astrophysicists previously believed that only supernovae could generate long gamma-ray bursts (GRBs), a 2021 observation uncovered evidence that compact-object mergers also can generate the ...
July 26, 2023 — An international team of scientists, including astrophysicists, report on a dedicated observational campaign on the Galactic microquasar dubbed GRS 1915+105. The team revealed features of a ...
July 18, 2023 — Astronomers used the state-of-the-art capability of VERA, a Japanese network of radio telescopes, to uncover valuable clues about how rapidly growing 'young' supermassive black holes form, ...
July 6, 2023 — Researchers have discovered the most distant active supermassive black hole to date with the James Webb Space Telescope (JWST). The galaxy, CEERS 1019, existed about 570 million years after the big ...
July 1, 2023 — The universe is expanding; we've had evidence of that for about a century. But just how quickly celestial objects are receding from each other is still up for ...
June 29, 2023 — Galaxies are not scattered randomly across the universe. They gather together not only into clusters, but into vast interconnected filamentary structures with gigantic barren voids in between. This ...
June 29, 2023 — Black holes, some of the most captivating entities in the cosmos, possess an immense gravitational pull so strong that not even light can escape. The groundbreaking detection of gravitational waves ...
June 29, 2023 — You can't see or feel it, but everything around you -- including your own body -- is slowly shrinking and expanding. It's the weird, spacetime-warping effect of gravitational waves passing ...
June 28, 2023 — For the first time, the James Webb Space Telescope has revealed starlight from two massive galaxies hosting actively growing black holes -- quasars -- seen less than a billion years after the Big ...
June 22, 2023 — Astronomers studying a powerful gamma-ray burst, may have detected a never-before-seen way to destroy a star. Unlike most GRBs, which are caused by exploding massive stars or the chance mergers of ...
June 21, 2023 — An international team of scientists has discovered that Sagittarius A* (Sgr A*), the supermassive black hole at the centre of the Milky Way, emerged from a long period of dormancy some 200 years ago. ...
June 7, 2023 — Last year, telescopes around the world registered the brightest cosmic explosion of all time. Astrophysicists can now explain what made it so ...
June 6, 2023 — An international team of astronomers observed the second one of the two supermassive black holes circling each other in an active galaxy OJ ...
June 5, 2023 — Although astrophysicists theoretically should be able to detect gravitational waves from a single, non-binary source, they have yet to uncover these elusive signals. Now researchers suggest looking ...
June 3, 2023 — Scientists have managed to weigh -- more precisely than any other technique -- a galaxy hosting a quasar, thanks to the fact that it acts as a gravitational lens. Detection of strong gravitational ...
June 2, 2023 — New theoretical research has shown that Stephen Hawking was likely right about black holes, although not completely. Due to Hawking radiation, black holes will eventually evaporate, but the event ...
June 2, 2023 — In the early 1980s, astronomers discovered gigantic, one-dimensional filaments dangling vertically near Sagittarius A*, our galaxy's central supermassive black hole. Now, astronomers have ...
May 29, 2023 — Black hole jets are known to emit x-rays, but how they accelerate particles to this high-energy state is still a mystery. Surprising new findings appear to rule out a leading theory, opening the door ...
May 23, 2023 — Astronomers have come up with what they say is some of their best evidence yet for the presence of a rare class of 'intermediate-sized' black hole that may be lurking in the heart of the ...
