A new ultraviolet mosaic from NASA's Galaxy Evolution Explorer shows a speeding star that is leaving an enormous trail of "seeds" for new solar systems. The star, named Mira (pronounced my-rah) after the latin word for "wonderful," is shedding material that will be recycled into new stars, planets and possibly even life as it hurls through our galaxy. Mira appears as a small white dot in the bulb-shaped structure at right, and is moving from left to right in this view. The shed material can be seen in light blue. The dots in the picture are stars and distant galaxies. The large blue dot at left is a star that is closer to us than Mira. Image credit: NASA/JPL-Caltech
NASA's Galaxy Evolution Explorer has spotted a surprisingly long comet-like tail behind a star streaking through space at supersonic speeds.

It is a fast-moving, older red giant that is shedding massive amounts of surface material.
