Gatsby, a black cat, has a white, spotted pattern resembling a galaxy of stars on his coat. He took the internet by storm after a video of him shared to Instagram on July 1 went viral.

Five million years ago, when humanity's ancestors were just learning to walk upright, a star was ejected from Sagittarius A*, the supermassive black hole at the center of the Milky Way Galaxy, at ...

So, working with the 400 billion number for the amount of stars, we must conclude that there are roughly 400 million black holes in our galaxy. There's no way of knowing for sure though. Black ...

A dwarf galaxy that appears to harbor a supermassive black hole far bigger than expected may have had most of its stars stolen from it by the Milky Way, scientists have proposed.

The first double-black hole galaxy was found in 2003 by accident, according to Comerford. She is trying to systematically uncover more. The findings should shed light on the evolution of black holes.

A supermassive black hole accidentally spotted by NASA's Hubble Space Telescope is now flying through space, leaving a breadcrumb path of stars behind it.

The galaxy, called GS-9209, formed most of its stars during a hyperactive burst of activity between 600 million and 800 million years after the Big Bang.Then, more than 12.5 billion years ago, it ...

“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.

It's as if the black hole basically hurled it out of the galaxy. Sponsor Message Han and his colleagues recently studied 21 of these hypervelocity stars at the fringes of the Milky Way.

Traditionally, the term galaxy referred to a collection of stars and gas; then, dark matter was added. “Now it seems that the need for stars may not be necessary in the definition,” she said.
