Astronomers think they might be able to detect black holes falling into wormholes using ripples in spacetime known as gravitational waves, but only if wormholes actually exist and
Supermassive black holes dot our universe, monstrous gravity wells that bind galaxies together and wreath themselves in whirling cocoons of dust that emit bright X-ray beams. Sometimes,
About 10 million light-years from Earth, a blurry galaxy named Mirach’s Ghost may help unravel a dark mystery: where the largest black holes in the universe came from.
In 2019, scientists witnessed a massive star 2.5 million times brighter than the sun disappear without a trace. Now, in a new paper published today (June 30) in
A signal from space first detected Aug. 14, 2019, may have come from a mystery object. And it might force physicists to rip up an old idea about
Physicists may finally have figured out how fast a black hole visible in our Milky Way is spinning, and in doing so gotten closer than ever to figuring
The center of the Milky Way is a puzzle of invisible, interconnected blobs. There are swooping tendrils of energy visible only in radio wavelengths, hourglass-shaped scars of X-ray
Streams of gas fall to their dooms, plunging into black holes, locked away from the universe forever. In their final moments, these gassy shreds send out one last
