The Hungriest Black Hole Ever Detected Gobbles a Sun-Sized Star Every Two Days

Supermassive black holes at the centres of galaxies can get absurdly huge, sometimes reaching masses billions of times greater than our Sun. The rate at which black holes grow can vary, but Australian astronomers have detected one such object with an unusually intense appetite, making it the fastest-growing black hole ever detected in the observable universe.

New Results Challenge Basic Ideas of Supermassive Black Holes

Galaxies have supermassive black holes at their centres—our Milky Way, for example, has its own 4-million-solar-mass one, Sagittarius A*. Some astronomers have previously thought that there’s a simple relationship between the galaxy’s size, the black hole’s mass, and how much light the black hole spits out while it eats up the things surrounding it. But a pair of papers studying the biggest star-eating behemoths imaginable seems to bust up that assumption. Read More >>

A Wild New Hypothesis for How the First Monster Black Holes Formed

It’s no secret that supermassive black holes are heartless beasts: These objects of immense gravity that let nothing, not even light escape, have fascinated astronomers since the early 20th century. While it’s believed that so-called supermassive black holes lurk at the center of most galaxies, including our own, there’s still much we don’t know about how they formed, or why, except to remind us of our own mortality.

Brightest Supernova Ever Seen Was Actually Something Much Darker

Last year, astronomers recorded the brightest supernova explosion ever seen. Follow up observations now suggest this cataclysmic event wasn’t a supernova at all, but rather, an extremely rare celestial phenomenon involving a supermassive black hole and a rather unfortunate star. Read More >>

This Entire Galaxy is Being Ravaged By its Supermassive Black Hole

A stunning new image captured by the Hubble Space Telescope shows a galaxy that’s being strangled by tentacles of gas and dust. The strange and intricate shape of this celestial object is caused by a supermassive black hole at its core — and it’s killing the host. Read More >>
