M82 is one of the most vigorous galaxies around, as this Hubble Space Telescope composite image attests. Winds from hot young stars, as well as powerful stellar explosions, blast debris away from the galaxy's disk (red filaments). The galaxy is giving birth to stars at about five times the rate of our home galaxy, the Milky Way. The activity is blowing away the gas and dust needed to give birth to even more stars, so in a few million years the rate of star formation will decline dramatically.
