Black holes

Astronomers will be alerted to gravitational waves faster than ever before as LIGO and other detectors "listen" to a universal symphony.

Supermassive black holes may create conditions akin to "cosmic intersections with failed traffic lights" that make collisions between smaller stellar-mass black holes inevitable.

Combining AI and observations of the Milky Way's supermassive black hole, scientists have reconstructed a 3D video of Sagittarius A* and its environment.

Astronomers have discovered the most massive stellar-born black hole ever seen in the Milky Way, and it lies relatively close to Earth.

The robotic telescopes of the Virtual Telescope Project have observed a quasar powered by a supermassive black hole 3 billion times as massive as the sun at the very edge of the universe

Some black holes are so massive they were likely created as smaller black holes that merged. Maybe we can use such black hole "children" to learn about the black hole "ancestors."

Don't rule out primordial black holes as dark matter suspects just yet! Particle-sized black holes may resist evaporation, surviving long enough to account for the universe's most mysterious stuff.

New observations provide an intriguing window into what happens when a slumbering black hole awakens to devour a star.

A quasar over three billion light-years away was found to be rather gentle on its host galaxy, allowing its black hole to keep growing.

A black hole may be punching through the disk of gas and dust surrounding a supermassive black hole, causing its giant neighbor to "hiccup."
