Today (Sept. 18) a unique airborne space observatory will perform its first scientific flight over Europe.
A black hole is a location in space that possesses so much gravity, nothing can escape its pull, even light. Learn more about what black holes are and the latest news.
Two huge bubbles of radio energy swirling out of the Milky Way's middle could be evidence of an ancient cosmic explosion — or maybe the start of a new one.
Researchers at LIGO and Virgo may have detected a gravitational-wave signal from the merger between a black hole and neutron star. This would be a major first.
Astronomers have been watching the black hole at the center of our galaxy for 20 years, and in May, they saw something they'd never seen before.
A cloaked black hole found lurking behind a cloud of gas dates to the early cosmic years of the universe.
It's time to find all the missing black holes. That's the argument advanced by a pair of Japanese astrophysicists who want to find "isolated black holes."
Black holes are mysterious objects of extreme density, with such strong gravitational attraction that even light cannot escape from their grasp if it comes near enough.
The biggest, oldest black holes in the universe shouldn't technically exist. A new study provides fresh evidence for the weird, "direct collapse" process that may have made them.
Astronomers are starting to get the goods on fast radio bursts, one of the most mysterious phenomena in the universe.
Black holes are engines of destruction on a cosmic scale, but they may also be the bringers of life.
A citizen-science project is asking people to trace spiral galaxies to help astronomers find intermediate-mass black holes.
