The Event Horizon Telescope (EHT) now spans the diameter of our planet and, when the vast project goes online, astronomers will get their first glimpse of the bright ring surrounding a supermassive black hole.
Despite the harsh environment created by the monster black hole lurking in the center of the Milky Way galaxy, new observations show that stars — and, potentially, planets — are forming just two light-years away from the colossal giant.
The world's biggest particle collider was back in operation Sunday after a two-year upgrade.
New simulations of the most energetic collisions in the universe are helping astrophysicists understand how gravitational waves are generated, possibly giving us an exciting glimpse into the future of gravitational astronomy.
Astronomers have detected a black hole embedded in the spiral arm of a galaxy 100 million light-years from Earth — but this isn’t any old black hole, it belongs to an extremely elusive class that may be the ‘missing link’ in black hole evolution.
Astronomers have discovered an out-of-place supermassive black hole -- 12 billion times more massive than the sun -- that inexplicably formed when the universe was less than 900 million years old.
It has long been assumed that the size of a supermassive black hole in a galaxy's core is intimately related to the number of stars that galaxy contains -- but it might not be that simple.
Astronomers studying an otherwise 'boring' galaxy over a billion light-years from Earth have been surprised to see a powerful storm erupt from its core.
