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.

Violent collisions between two galaxies of equal sizes are more likely to power up both of the supermassive black holes at the galactic centers.
