Johnny Appleseed of the CosmosA new ultraviolet mosaic from NASA's Galaxy Evolution Explorer shows a speeding star named Mira (pronounced my-rah) that is leaving an enormous trail of "seeds" for new solar systems.2. A Real Shooting StarThis artist's animation illustrates a star flying through our galaxy at supersonic speeds, leaving a 13-light-year-long trail of glowing material in its wake.Play animation: + Play animation - Lower resolution (Quicktime - 6.5Mb) 3. Evolution of Mira's Enormous TailThis chart illustrates the length (top) and age (bottom) of a long comet-like tail of material trailing behind a speeding star called Mira (pronounced My-rah).4. Anatomy of a Shooting StarA close-up view of a star racing through space faster than a speeding bullet can be seen in this image from NASA's Galaxy Evolution Explorer.5. Supersonic BulletA bullet traveling through air at about 1.5 times the speed of sound can be seen in this image.6. Mira's Tail There All AlongAs this composite demonstrates, Mira's tail is only visible in ultraviolet light (top), and does not show up in visible light (bottom).
