Video: The latest look at 'first light' from Chandra

NASA's Chandra X-ray Observatory has captured many spectacular images of cosmic phenomena over its two decades of operations, but perhaps its most iconic is the supernova remnant Cassiopeia A.

Evidence found for cloaked black hole in early universe

A group of astronomers, including Penn State scientists, has announced the likely discovery of a highly obscured black hole existing only 850 million years after the Big Bang, using NASA's Chandra X-ray Observatory. This ...

Chandra X-ray observatory celebrates its 20th anniversary

On July 23, 1999, the Space Shuttle Columbia blasted off from the Kennedy Space Center carrying the Chandra X-ray Observatory. In the two decades that have passed, Chandra's powerful and unique X-ray eyes have contributed ...

X-rays spot spinning black holes across cosmic sea

Like whirlpools in the ocean, spinning black holes in space create a swirling torrent around them. However, black holes do not create eddies of wind or water. Rather, they generate disks of gas and dust heated to hundreds ...

Does the gas in galaxy clusters flow like honey?

We have seen intricate patterns that milk makes in coffee and much smoother ones that honey makes when stirred with a spoon. Which of these cases best describes the behavior of the hot gas in galaxy clusters? By answering ...

Chandra finds stellar duos banished from galaxies

Scientists have found evidence that pairs of stars have been kicked out of their host galaxies. This discovery, made using data from NASA's Chandra X-ray Observatory, is one of the clearest examples of stellar pairs being ...

Image: Storm in the Teacup quasar

This image shows a quasar nicknamed the Teacup due to its shape. A quasar is an active galaxy that is powered by material falling into its central supermassive black hole. They are extremely luminous objects located at great ...
