The light of a red star is warped and magnified by its dead-star companion, as detected by NASA's Kepler space telescope.

The spectacular barred spiral galaxy NGC 6872 has ranked among the biggest stellar systems for decades. Now a team of astronomers from the United States, Chile and Brazil have crowned it the largest-known spiral based on archival data from NASA's Galaxy Evolution Explorer mission.

What was once a fairly average star, not much different than our sun, can be seen unraveling at the seams in this new image from the Spitzer and GALEX space telescopes.

NASA is lending the Galaxy Evolution Explorer (GALEX) to the California Institute of Technology (Caltech) in Pasadena, where the spacecraft will continue its exploration of the cosmos.

Astronomers have gathered the most direct evidence yet of a supermassive black hole shredding a star that wandered too close.

NASA's Galaxy Evolution Explorer was placed in standby mode today as engineers prepare to end mission operations, nearly nine years after the telescope's launch.
