A group of unusual giant black holes may be consuming excessive amounts of matter, according to a new study using NASA's Chandra X-ray Observatory.

My mom works for NASA, for a telescope that studies X-rays from space. She told me about how the telescope, called Chandra, was launched into space aboard the Space Shuttle.

Chandra's excellent X-ray vision enabled the astronomers to determine that the X-rays from NGC 6388 were not coming from a black hole at the center of the cluster.

A black hole is formed when a massive star is squashed into an incredibly tiny volume.

In space, explosions of actual stars are a focus for scientists who hope to better understand the lifecycle of their births, lives, and deaths.

On Earth, precipitation happens when water is heated by the Sun and forms steam. Sometimes, something similar happens in galaxies.

Researchers used Chandra to look at some of the largest known galaxies lying in the middle of galaxy clusters.

Astronomers found that this intermediate-mass black hole is producing a jet that appears to be squelching the formation of stars around it.

Supermassive black holes are famous for their ability to swallow anything - even light.

Astronomers think magnetars may be created when some massive stars die in a supernova explosion.
