This is a spiral galaxy known as M47. It is composed of about 100 billion stars and is located 32 million light-years away from Earth, near the constellation Pisces. The arms of the spiral are made up of dust and gas, as well as blue star clusters. The red sections in the galaxy are star forming regions. The color comes from hydrogen gas. M47 is about 30,000 light-years across, and this photo was constructed from shots taken by the Hubble Space Telescope between 2003 and 2005.Friday, December 7, 2007
