Press Release: Speeding Bullet Star Leaves Enormous Streak Across Sky
NASA's Galaxy Evolution Explorer has spotted an amazingly long comet-like tail behind a star streaking through space at supersonic speeds. The star, named Mira after the Latin word for "wonderful," has been a favorite of astronomers for about 400 years. It is a fast-moving, older star called a red giant that sheds massive amounts of surface material.
-
From NRAO: "Missing Mass" Found in Recycled Dwarf Galaxies
Astronomers studying dwarf galaxies formed from the debris of a collision of larger galaxies found the dwarfs much more massive than expected, and think the additional material is "missing mass" that theorists said should not be present in this kind of dwarf galaxy.
-
Press Release: 'That's Hot!' GALEX Celebrates Four Years in Space
NASA's Galaxy Evolution Explorer is celebrating its fourth year in space with some of M81's "hottest" stars.

Press Release: GALEX Finds Link Between Big and Small Stellar Blasts
Proof that certain double star systems can erupt in full-blown explosions and then continue to flare up with smaller bursts has been spotted by the ultraviolet eyes of NASA's Galaxy Evolution Explorer.
-
Press Release: NASA Telescope Sees Black Hole Munch on a Star
A giant black hole has been caught red-handed dipping into a cosmic cookie jar of stars by NASA's Galaxy Evolution Explorer. This is the first time astronomers have seen the whole process of a black hole eating a star, from its first to nearly final bites.
-
Press Release: Huge Black Holes Stifle Star Formation
Supermassive black holes in some giant galaxies create such a hostile environment, they shut down the formation of new stars, according to NASA Galaxy Evolution Explorer findings published in the August 24th issue of Nature.

A new image from NASA's Galaxy Evolution Explorer shows that a galaxy once thought to be rather plain and old is actually endowed with a gorgeous set of young spiral arms.
-
Press Release: NASA Telescope Catches Surprise Ultraviolet Light Show
It was a day like any other for a nearby star named GJ 3685A until it suddenly exploded with light. At 2 p.m. Pacific time, April 24, 2004, the detectors on NASA's Galaxy Evolution Explorer ultraviolet space telescope nearly overloaded when the star abruptly brightened by a factor of at least 10,000. After the excitement was over, astronomers realized that they had just recorded a giant star eruption, or flare, about one million times more energetic than those from our Sun.
