The orange speckles in a new image from NASA's Chandra X-ray Observatory add another dimension to the first-ever image of a black hole.

Put yourself at the center of an ever-changing Milky Way with this new immersive video of the galaxy's core.

A powerful quasar has caused a raging storm in a distant cosmic structure known as the "Teacup."

Astronomers think they've found a new clue in their continuing quest to solve one of the most substantial mysteries of the cosmos: where about a third of the universe's matter is hiding.

Dark energy is even more mysterious than astronomers had thought, a new study suggests.

The crumbs left over from a supermassive black hole's recent meal have allowed scientists to calculate the monster's rotation rate, and the results are mind-boggling.

Is that the USS Enterprise blurring as it makes the jump to warp speed? Well, no. But a new photo of the galaxy cluster Abell 1033 certainly does call the famous "Star Trek" starship to mind.

NASA's Chandra X-ray Observatory has bounced back from the glitch that knocked it offline two weeks ago.

More than 2 million mph (1 million meters per second) — that's how incredibly fast some stuff in space is moving, according to new research using the Chandra X-Ray Observatory.
