Messier 108 is a barred spiral galaxy found 45 million light years away. It is viewed end-on from Earth. It was discovered by Mechain 3 days after M97 but didn't make it into the original Messier catalog. It was added in 1954 based on the original notes by Messier. This galaxy is interesting as it contains many shells of expanding gas called supershells. These areas may indicate active star formation and supernovae events.
