M97 (Owl Cluster) and M108 (Surfboard Galaxy)

Captured on 4/13/23

[Lower right in photo] M97, the Owl Nebula (NGC 3587), is a starburst planetary nebula about 2,030 light-years from Earth in the constellation Ursa Major.  Its age is estimated to be about 8,000 years and is believed to have formed from the outflow of material from the stellar wind of a central star.  The nebula itself is arranged in three concentric shells/envelopes.   The name of the nebula comes from its somewhat owl-like appearance which results from the barrel-like inner shell that is not symmetrical but forms a barrel-like structure.

[Upper left in photo] M108, the Surfboard Galaxy (NGC 3556), is a barred spiral galaxy about 28 million light-years away from Earth in the constellation Ursa Major. This galaxy is a barred spiral galaxy with loosely wound arms and has an estimated mass equivalent to about 125 billion of our suns and contains about 300 globular clusters of stars.
