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


Spiral Galaxy NGC 3147:

NGC 3147 is a spiral galaxy in the constellation of Draco. This galaxy was also the host of Supernova 1972 H, another Type I. There are tightly wound multiple spiral arms, which can be traced right to the small, nucleus. The arms are highly branched. Note the faint-surface-brightness arm on the outside of the bright arm on the north side. Whenever two arm systems of different surface brightness occur, the fainter set is always on the outside. The arm pattern consists of spiral fragments that can be traced as individual continuous segments without branching for only about one-quarter turn.
