In a "rite of passage," the JAXA/NASA X-ray telescope XRISM has mapped in detail Cygnus X-3, a curious binary system with a ...

For decades, astronomers have puzzled over how the supermassive black holes residing in the center of galaxies form. Now, ...

But researchers can look to see if the gravity of a black hole is affecting nearby objects, including stars. And the researchers knew that the stars in this particular cluster were being ...

Chandra X-ray Observatory observations of the Perseus galaxy cluster's black hole and M87's jet have been turned into sound ...

A quasar is an exceptionally bright and uncommon supermassive black hole found at the core of a galaxy. NASA researchers have ...

instead of one massive black hole, lurking at the heart of the globular cluster NGC 6397. Globular clusters are extremely dense stellar systems, which host stars that are closely packed together.

Artist’s view of a massive black hole mergers in a cluster, possibly like GW190521, a gravitational wave observation by LIGO/Virgo. (credit: Wikimedia Commons) This black hole, called V404 Cygni ...

Hubble detected the black hole by observing the motion of stars near the cluster's centre, which suggested a massive, unseen object was pulling on them. The stars' motions revealed a consistent ...

The energetic streams are together 23 million light-years in length—roughly as long as 140 Milky Way galaxies lined end to end Shi En Kim The black hole, if confirmed, is in the star cluster ...

Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity. And anything that ...

By observing a cluster of stars near the hole ... The result will help scientists better understand the physics of black holes. The Very Large Telescope (VLT) in Chile found evidence for ...
