The new Wide Field Camera 3 on Hubble was employed to photograph Neptune in near-natural color on August 28, 2010, when the planet was near its opposition. The version on the right has enhanced contrast, revealing a dark ring of clouds around the south pole. Triton would be visible to Hubble if it were in the frame, but it was not in the camera field of view at the time of the observation.
