It's the closest supermassive black hole outside of our galaxy. Space. That galaxy next door? It's home to a monster black hole. March 6, 2025 1:05 PM ET. Heard on All Things Considered.

Researchers have found that the supermassive black hole in the center of our Milky Way galaxy, known as Sagittarius A*, is spinning so rapidly that it is altering the fabric of space-time around it.

The Milky Way may have had a second black hole at its heart between 10 billion and 10 million years ago—one that acted a bit like a star goalkeeper.. This is the conclusion of a study by ...

By looking at radio waves and X-ray emissions, a team of physicists has found the supermassive black hole Sagittarius A* to be spinning— and altering space-time around it.

A galaxy 300 million light-years away in space suddenly brightened four years ago. Astronomers think they have witnessed a black hole waking up.

The type of black hole that’s sitting in the center of a galaxy is different. This is a supermassive black hole, or SMBH, and — as its name implies — it’s much heftier.

Scientists watched as a three-quasar system merged in a supercomputer simulation of the universe to birth a black hole 300 billion times as massive as the sun.

“The classic location where you expect massive black holes to be in a galaxy is in the center, like our Sag A* at the center of the Milky Way,” explained lead researcher Yuhan Yao of UC Berkeley.

Black holes are one of the most mysterious cosmic phenomena, despite how much we continue to learn about them. While considered a mathematical possibility for many years, the first black hole wasn ...
