Using NASA’s Chandra X-ray space telescope, scientists have investigated if nearby exoplanets could support life, or if their stars are blasting them with too much deadly high-energy radiation.

Using data from the Hubble and Chandra space telescopes, scientists have determined that dark matter ghosted through the wreckage of two colliding galaxy clusters over 5 billion light-years away.

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.
