This is a picture of a starburst galaxy named M82. It's common name is the Cigar Galaxy because of its elongated physical appearance. This galaxy is experiencing supernovas and strong winds from massive stars. This is causing a burst of star formation within the galaxy that is producing a prodigous outflow of material. You can see evidence of the superwind from the galaxy's central regions. The burst of star formation should last up to 100 million years.
