This Hubble image shows various distant galaxies in the constellation of Cetus: most of the galaxies are very small, but there are a few larger galaxies and some stars where detail can be made out; in the center there is an elliptical galaxy with a brightly glowing core and a broad disk; a reddish, warped ring of light, thicker at one side, surrounds its core; a small galaxy intersects the ring as a bright dot.
