Stellar stream. Hubble Space Telescope (HST) image of a stellar stream in the Andromeda Galaxy. A stellar stream is a band of stars thought to be the remains of a companion galaxy torn apart and engulfed by Andromeda. Andromeda, the nearest large galaxy to our own, is located 2.5 million light years away in the constellation of the same name. Hubble's position above the distorting effect of the atmosphere, combined with the galaxy's relative proximity, means that the galaxy can be resolved into individual stars, rather than the cloudy white wisps usually seen in observations of galaxies. Image obtained by the Advanced Camera for Surveys.
