These 2 images provide views of weather on opposite hemispheres of Neptune. The blue color is a result of the absorption of the red light by methane in the upper atmosphere. Clouds elevated above the methane layer tend to be 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, with winds blowing nearly 900 mph, is centered on the dark blue belt, just south of the equator. Farther south, the green belt indicates a region where the atmosphere absorbs blue light.
