The Hubble telescope has peered deep into Uranus's atmosphere to see clear and hazy layers created by a mixture of gases. Using infrared filters, Hubble captured detailed features of three layers of the planet's atmosphere.
Hubble's images are different from the ones taken by the Voyager 2 spacecraft, which flew by Uranus 10 years ago. Those images - not taken in infrared light - showed a greenish-blue disk with very little detail. The infrared image allows astronomers to probe the structure of the planet's atmosphere, which consists mostly of hydrogen with traces of methane.
