Follow this Link to a NASA Web site on supernovas. It has a very nice animation and a description of what these objects are.

Barred Spiral Galaxy NGC 5921:

NGC 5921 is located in the Constellation of Serpens. The disk is full of H II regions in the two spiral arms that emerge from the ends of the stellar bar, where many H II regions are clumped. The nucleus is very bright and compact, and it seems to connect with the string of H II regions along the bar. All of the many H II regions show intensive star formation. The star formation is enhanced at both ends of the bar.
