Twisted Galaxy

Featured on November 5, 2018

Messier 101 is one of the most beautiful of all spiral galaxies. It consists of a bright core that contains mainly older, redder stars, enwrapped in brilliant spiral arms populated by many younger, bluer stars. Dark dust lanes, which contain the raw ingredients for new stars, outline the spiral arms. The galaxy is in Ursa Major, the great bear, which contains the stars of the Big Dipper. [NASA/ESA]
