[edit] Summary

An image of Hoag's Object, a non-typical galaxy of the type known as a ring galaxy, discovered in 1950 by astronomer Art Hoag, who initially thought it to be a planetary nebula. Serendipitously, from the perspective of our solar system what appears to be an even more distant ring galaxy is plainly visible within the gap between this galaxy's central body of mostly yellow stars and the outer ring of blue stars.
