Located 500 million light-years away in the constellation Sculptor, the galaxy looks like a wagon wheel. The galaxy’s nucleus is the bright object in the center of the image; the spoke-like structures are wisps of material connecting the nucleus to the outer ring of young stars. The galaxy’s unusual configuration was created by a nearly head-on collision with a smaller galaxy about 200 million years ago.
