M 83 is often called the "Southern Pinwheel" because of its
long, distinct spiral arms (the other "Pinwheel" being M 101).
The nucleus and central "bar" contain a population of older, yellow
stars. Along the arms of the galaxy are knots of red hydrogen nebula
where new stars are forming, and blue knots of young star clusters.
M 83 is 15 million light years away in the constellation Hydra.
