This spectacular spiral galaxy is known to astronomers as Messier 83. Colloquially, it is also called the Southern Pinwheel due to its similarity to the more northerly Pinwheel galaxy Messier 101. NASAs Spitzer Space Telescope shows us, in spectacular detail, the infrared structure of what many think of as our own Milky Way galaxys smaller cousin.

This image of the Pinwheel Galaxy, also known as M101, combines data in the infrared, visible, ultraviolet and X-rays from four of NASA's space-based telescopes. This multi-spectral view shows that both young and old stars are evenly distributed along M101's tightly-wound spiral arms.

Pinwheel Galaxy. The Pinwheel Galaxy in the constellation Ursa Major (the Greater Bear) is a “grand design” spiral, meaning that it has well-defined spiral arms and dust lanes that extend all the way around the body of the galaxy. It was discovered in 1781 by astronomer Pierre Méchain, and included as object number 101 in Charles Messier’s list of celestial objects.
