Jan. 17, 2024 Researchers have discovered the oldest black hole ever observed, dating from the dawn of the universe, and found that it is 'eating' its host galaxy to ...
Jan. 16, 2024 Astronomers have created the most sensitive radio image ever of a globular cluster, an ancient ball of tightly-packed ...
Jan. 12, 2024 Researchers at NASA's Goddard Space Flight Center have discovered X-ray activity that sheds light on the evolution of ...
Jan. 11, 2024 Astrophysicists have confirmed the accuracy of an analytical model that can unlock key information about supermassive black holes and the stars they ...
Dec. 4, 2023 An entirely new way to probe how active black holes behave when they eat has been discovered by an international team of ...
Dec. 4, 2023 A star near the supermassive black hole at the center of the Milky Way Galaxy originated outside of the Galaxy according to a new study. This is the first time a star of extragalactic origin has been ...
Dec. 4, 2023 The prevailing assumption has been that Einstein's theory of gravity must be modified, or 'quantized', in order to fit within quantum theory. This is the approach of two leading ...
Nov. 29, 2023 Cutting-edge computer simulations combined with theoretical calculations are helping astronomers better understand the origin of some of the universe's most energetic and mysterious light shows ...
Nov. 28, 2023 Scientists have announced the discovery of nearly 300 gamma ray ...
Nov. 14, 2023 The one thing everyone knows about black holes is that absolutely everything nearby gets sucked into them. Almost everything, it turns out. Astrophysicists have now determined conclusively that ...
Nov. 6, 2023 Almost every large galaxy has a supermassive black hole at its center. An international research team has recently observed the Circinus galaxy, which is one of the closest galaxies to the Milky Way, ...
Nov. 2, 2023 New observations down to light-year scale of the gas flows around a supermassive black hole have successfully detected dense gas inflows and shown that only a small portion (about 3 percent) of the ...
Oct. 19, 2023 Researchers have shown it's theoretically possible for black holes to exist in perfectly balanced pairs -- held in equilibrium by a cosmological force -- mimicking a single black ...
Oct. 10, 2023 An unexpectedly high number of young stars has been identified in the direct vicinity of a supermassive black hole and water ice has been detected at the center of our ...
Sep. 27, 2023 The supermassive black hole at the heart of galaxy M87, made famous by the first picture of a black hole shadow, has yielded another first: the jet shooting out from the black hole has been confirmed ...
Sep. 25, 2023 Astronomers have found a striking link between the amount of dust surrounding a supermassive black hole and the strength of the radio emission produced in extremely bright ...
Sep. 20, 2023 While previous researchers have hypothesized that black holes eat slowly, new simulations indicate that black holes scarf food much faster than conventional understanding suggests. Some quasars ...
Sep. 12, 2023 At the center of every galaxy is a supermassive black hole. Beyond a certain size, these become active, emitting huge amounts of radiation, and are then called quasars. It is thought these are ...
Sep. 8, 2023 A new article hints at the existence of several black holes in the Hyades cluster -- the closest open cluster to our solar system -- which would make them the closest black holes to Earth ever ...
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 ...
