Spiral Galaxy Messier 100 - Universe Today
If our Milky Way looked in the mirror, this is what it would probably see. This is a photograph of galaxy Messier 100, located about 60 million light-years away. It presents an intricate structure with a bright core, two large arms, and a pair of fainter spiral arms. Japanese amateur astronomer Shoji Suzuki and Italian astronomer Marco Migliardi recently discovered a Type-Ia supernova in M100 on February 4, 2006.
