supermassive black holes

The findings expand our knowledge of black holes and the galaxies within which they are often found.

Astronomers have spotted a black hole spewing out vast amounts of incredibly cold gas.

Scientists think that at the heart of nearly every galaxy lies a supermassive black hole (SMBH) with immense gravity.

The galaxy belongs to a recently discovered, rare and unusual class of stellar systems known as ultracompact dwarfs.

The image reveals in incredible detail a fiery region surrounding the supermassive black hole that lies at the heart of the Milky Way.

"It was surprising, but you like to be surprised in science."

The event horizon is the point of no return beyond which nothing, not even light, can escape the immense gravitational pull of the black hole.

The black holes surround the supermassive black hole at the center of the Milky Way.

Light from the jets can outshine entire galaxies.

The planets face supernovas, gamma-ray bursts and gravity-disrupting stars in the crowded center of the Milky Way.

More than half of these "ultramassive" black holes have a mass 10 billion times greater than the Sun.

They'e even predicting where the event is most likely to occur.

How supermassive black holes formed so quickly after the start of the universe has long baffled scientists.
