A newfound giant black hole nearly as massive as 7 billion suns is dozens of times larger than astronomers expected given its host galaxy's size, researchers say.
Astronomers have witnessed, for the first time, a relativistic collision in a black hole jet millions of light-years from Earth.
Powerful jets of material spewing from the edge of monster black holes may be more likely to arise where two galaxies have merged together.
Astronomers have found a quartet of quasars embedded in a single cloud of cold gas, a discovery that challenges currently held theories about how these rare objects form.
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.
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 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.
