Chandra

To celebrate the 25th anniversary of the flagship Chandra X-ray observatory, NASA released a behind-the-scenes look at the work it takes to keep the $1.5 billion telescope flying in space.

Newly released images from NASA's Chandra X-ray telescope capture a cloud complex called Rho Ophiuchi, the Orion Nebula, a spiral galaxy named NGC 3627 and a galaxy cluster known as MACS J0416.

Supermassive black holes that are blasting out beams of high-energy particles killing star formation in their galaxies are shifting targets like real-life Death Stars.

NASA's sonification project has done it again, this time turning the Galactic Center into a perfectly dissonant symphony.

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.
