Hubble Captures Changing Weather and Appearance of Uranus.

The Hubble Space Telescope has taken new images of Jupiter and Uranus, revealing recent changes in their atmospheres. The images show intriguing atmospheric activity on Uranus, including ice-crystal clouds composed of methane and a polar cap dominated by a few storms. Jupiter's atmosphere is famously turbid, with stormy weather visible in the images taken by Hubble, including a series of storm systems known as a "vortex street" and the Great Red Spot. Hubble, which launched in 1990, has imaged galaxy mergers, measured the mass of distant stars, and studied other NASA missions.
