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.
Are you ready to get "spaghettified"? Julian has the gooey, stretchy, bizarro physics behind a human's leap into a supermassive black hole.
A surprisingly massive black hole has been discovered in the core of a small, compact galaxy -- a finding that appears to be a weird cosmic contradiction.
Quasars are the brightest objects in the universe, and display a mysterious diversity in their appearance that has puzzled astronomers for more than two decades.
Astrophysicists have analyzed two decades-worth of X-ray data and discovered three events inside galactic cores that can be interpreted in only one way: stellar destruction. Continue reading →
