New calculations reveal what two supermassive black holes about to merge would look like in ultraviolet and X-rays.
Astronomers have seen a star’s light redden as it passed our galaxy’s central black hole, just as general relativity predicts.
Astronomers have watched the growth of a jet fueled by a shredded star.
Hoping for faster-than-light travel? Wormholes aren't the paths you're looking for.
Astronomers have discovered three more red, dusty objects near the Milky Way’s central black hole that could be merged stars.
New simulation work suggests that galaxies like the Milky Way could be home to a dozen supermassive black holes.
Astronomers have discovered a supermassive black hole scarfing down gas just 690 million years after the Big Bang.
A team of astronomers has found signs of small stars forming within a few light-years of the Milky Way’s central black hole.
LIGO has detected another black hole merger, raising the tally to five.
Gas flows in the early universe may have kept clouds from collapsing too soon, enabling them to grow into massive black hole seeds.
Scientists with the gravitational-wave observatory announce another discovery, this time of a black hole merger twice as far away as previous detections.
What’s inside a black hole? Wormholes? Alternate universes? If you fell into a black hole, only one thing’s for sure: its tidal forces would kill you.
Learn what a black hole is, what we mean by “singularity” and “ergosphere,” and why we think black holes are real.
