Interplanetary shocks caused by two powerful bursts of solar wind travelling from the Sun to Uranus were captured with the STIS instrument. were able to discover aurorae present on this world. Instead of a monochrome, featureless world, we at last found the active atmosphere we had expected all along.īy overlaying Hubble Space Telescope data from 20 atop Voyager 2's views of Uranus, we. There are dark spots and light spots, hazes and clear regions, with differential colors at different Uranian latitudes.
There are swirling clouds, storms, and even characteristic atmospheric bands. We didn't have another mission ready to go at that time, but we did have the Hubble Space Telescope.Īs you can see, above, there are all the features you would have hoped for the first time.

Infrared peers through the methane haze, revealing belts of clouds plus bright storms that extend high above most of the surrounding clouds. In optical light, Uranus looks like a featureless blue-green marble, because methane in its upper atmosphere absorbs red wavelengths of light. third-largest planet in the solar system. An infrared view from the Keck Telescope shows details in the atmosphere of Uranus, the.
