About this object

SH2-224 is a supernova remnant in the constellation Auriga. It is very faint and required many hours of exposure time to adequately highlight the nebula. This remnant of an exploded star is thought to be about 15,000 light years distant. It is thought that the material you see here was from a star which exploded between 15,000 and 20,000 years ago. Some of the red emission seen in the upper right corner of the image is from a second supernova remnant which lies just outside the field of view.
