Neptune
Views of weather on opposite hemispheres of Neptune. Taken Aug. 13, 1996. The predominant blue color of the planet is a result of the absorption of red and infrared light by Neptune's methane atmosphere. Clouds elevated above most of the methane absorption appear white, while the very highest clouds tend to be yellow-red as seen in the bright feature at the top of the right-hand image. Neptune's powerful equatorial jet -- where winds blow at nearly 900 mph -- is centered on the dark blue belt just south of Neptune's equator.
The images are part of a series of images made by Hubble during nine orbits spanning one 16.11-hour rotation of Neptune.
