M58 (NGC 4579) is a barred spiral galaxy appearing within the constellation Virgo. Not much detail shows, but it isn't a bad photo, considering it is approximately 68 million light-years away from Earth. An infrared image taken by the Spitzer Space Telescope.
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.
