Hubble Telescope Reveals Changing Appearance of Uranus and Jupiter.

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 a polar cap dominated by a few storms, while Jupiter's atmosphere is characterized by swirling cyclones. Hubble, which launched in 1990, has imaged galaxy mergers, measured the mass of distant stars, and studied other NASA missions.
