Description: Mira A is a red giant variable star in the constellation Cetus. This ultraviolet-wavelength image mosaic, taken by NASA's Galaxy Evolution Explorer, shows a comet-like "tail" stretching 13 Light-years across space. The "tail" consists of hydrogen gas blown off of the star, with the material at the furthest end of the "tail" having been emitted about 30,000 years ago. The tail-like configuration of the emitted material appears to result from Mira's uncommonly high speed relative to the Milky Way galaxy's ambient gas-- about 130 kilometers per second.Mira itself is seen as a small white dot inside a blue bulb. You could also see many stars and galaxies at the image.
