Einstein believed that black holes didn't really exist. But they do: that much we know. We don't know much else about them.

Simulations of highly magnetized stars that explode and collapse into black holes show that they transfer their magnetic fields to the disk of swirling matter that forms around the new black hole.

XMM-Newton proved particularly critical to studying Ansky’s behavior, since it is the only telescope sensitive enough to capture fainter background X-ray light amid the black hole’s stronger X ...

A black hole in a distant galaxy has kept astronomers hooked to its quasiperiodic eruption activity, which is not a regular phenomenon.

DESI is an international experiment with more than 900 researchers from over 70 ... quasars (extremely distant yet bright objects with black holes at their cores) by the time the project ends.

the reverse of black holes, could exist. Rather than sucking things like black holes, these could eject matter, energy, and even time. To simplify calculations, the study uses a planar black hole ...
