HPP previews Black Hole Havoc, a arcade adventure from Cosmic Bros. Despite initial worries about crank control, this is a great game with surprising features.

"Theories involving substantial formation of stars prior to or together with the black hole formation and growth are very ...

Views of a massive galaxy cluster Abell 2256 have been captured by NASA’s Chandra X-ray Observatory, ESA’s XMM-Newton and ...

New research is shedding light on what researchers call "lite" intermediate-mass black holes, which are smaller, but still ...

Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

Astronomers searching for massive black holes shredding stars found one in an unusual place -- 2,600 light years from the core of a galaxy. The roque black hole may be from an earlier merger with ...

“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 ...

The rest are associated with the central black holes of galaxies. In fact, at the center of the host galaxy there is a different supermassive black hole weighing 100 million times the mass of the sun.

If we know there’s one wandering black hole so close to us in our own galaxy, then there are almost certainly others. Astronomers estimate there may be as many as 100 million isolated black ...

It is estimated that the Sausage Galaxy's central black hole was some 300 times less massive than Sgr A*—with the two merging around 10 million years ago.

Because our own galaxy’s central black hole is roughly a thousand times less massive than M87*, the churning maelstrom around Sagittarius A* can change about a thousand times faster, too ...

Even more surprisingly, both the disk and black hole were rotating at a 90-degree angle relative to the rest of the galaxy, meaning both features are essentially "lying on their sides," NASA said.
