Hubble Watches Uranus

Release date: Nov 20, 1997 12:00 AM (EST)

Using the Hubble telescope's visible-light camera, astronomers for the first time this century have detected clouds in the Northern Hemisphere of Uranus. The snapshots show banded structure and multiple clouds. Using these images, astronomers plan to measure the wind speeds in the Northern Hemisphere for the first time.

The clouds can be seen along the planet's right edge [the bright dots]. Another cloud [faint white dot] is barely visible near the bottom of the blue band. The clouds are almost as large as continents on Earth, such as Europe.
