Two of NASA's flagship space telescopes, Hubble and Chandra, may have less money to spend if budget predictions come through. NASA may reallocate funds to newer missions.

A distant galaxy is alone because it devoured the other galaxies that once surrounded it, a new study suggests.

Using the Chandra X-ray Observatory, researchers conducted the most in-depth study of planet-killing stars ever.

Astronomers using NASA's Chandra Observatory to watch galaxy collisions in the cluster Abell 98 have found what may be evidence of the universe's missing matter.

Four of the first science-quality images from NASA's James Webb Space Telescope have received a boost from X-ray vision.

Using data from NASA's Chandra X-ray Observatory, Hubble Space Telescope and recently retired Spitzer Space telescope, astronomers traced the timeline of a supernova explosion called SNR 0519.

A small galaxy swallowed by a larger spiral galaxy deposited a supermassive black hole as it was violently ripped apart and consumed.

Scientists have measured how fast a supermassive black hole is spinning, and the result might give us a clue about how the giant formed.

The Chandra X-ray Observatory has found growing intermediate-mass black holes in over two dozen galaxies.
