| M82: Starburst Galaxy with a Superwind (October 10, 2011) |
The galaxy pictured above is M82, a starburst galaxy known as the Cigar Galaxy for its elongated appearance. Superwinds from the galaxy's center are pictured above. The reddish lines that are pictured above are emissions from filaments of hydrogen gas. These filaments extend over 10,00 light-years The star formation occurring in M82 because of the close encounter with the bear by M81 galaxy should last for another 100 million years. That's a long time!
