Hypervelocity stars (HVSs) were first theorized to exist in the late 1980s. In 2005, the first discoveries were confirmed.

"Our measurements imply that the supermassive black hole mass is 10% of the stellar mass in the galaxies we studied." ...

An international team of researchers has detected a binary star orbiting near Sagittarius A*, the supermassive black hole ...

Researchers have observed strange goings-on around a supermassive black hole located nearly 300 million light years away.

The Hubble Space Telescope has imaged a "200,000 light-year-long trail of newborn stars" that may have been left behind by a ...

A new form of black hole archeology, linking spin to gas and dust, has revealed that these cosmic titans spin faster than ...

Supermassive black holes are seen as sources of wanton cosmic destruction, but there may be more to their powerful influence ...

By combining data from NASA’s IRAS and NuSTAR telescopes, scientists have uncovered more hidden supermassive black holes than earlier estimates suggested. Their findings indicate that over a third of ...

Black holes might all have hearts of pure darkness, but many cloak themselves in rings of fire that blaze like little else in ...

This makes it slightly less massive than the Milky Way's supermassive black hole Sagittarius A* (Sgr A*). Prior investigations of this event have suggested that the star involved in these flares ...

Supermassive black holes can fuel their own growth by cooling and recycling gas, creating a continuous cycle of feeding and ...

If the putative object were a smaller black hole, it would’ve plunged headlong through the accretion disk to merge with its supermassive mate—and if it were a normal star, it should’ve been ...
