M83 is a grand design spiral galaxy also known as the Southern Pinwheel Galaxy. New research found clouds of gas moving strangely in the galaxy. These clouds could have come from an external source and are triggering more star formation. Image Credit: NASA, ESA and the Hubble Heritage Team (STScI/AURA); Acknowledgment: W.
