New kind of cosmic flash may reveal something never seen before: Birth of a black hole
(Phys.org) —When a massive star exhausts its fuel, it collapses under its own gravity and produces a black hole, an object so dense that not even light can escape its gravitational grip. According to a ...
Mysterious X-ray signal intrigues astronomers
(Phys.org) —A mysterious X-ray signal has been found in a detailed study of galaxy clusters using NASA's Chandra X-ray Observatory and ESA's XMM-Newton. One intriguing possibility is that the X-rays are ...
