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.

NASA's Chandra X-ray Observatory remains on course to bounce back from its gyroscope issues soon, mission team members said.

Cataclysmic mergers of the superdense stellar corpses known as neutron stars may be common across the cosmos, a new study suggests.

NASA has identified the glitch that sent its Chandra X-ray Observatory into a protective safe mode last Wednesday (Oct. 10). The scope should be up and running again next week, agency officials said.

The Chandra X-ray Observatory, which has been observing the universe in high-energy light since 1999, entered a protective "safe mode" on Wednesday (Oct. 10).

A giant ring of black holes has been discovered 300 million light-years away, offering new clues about what happens when galaxies collide.

The Spitzer Space Telescope launched into orbit around the sun on Aug. 25, 2003, kicking off a long and diverse mission that has produced groundbreaking finds in a number of different fields.

Researchers at NASA's Chandra X-ray Observatory may have watched a young star devouring a planet.
