- THE GIANT PLANET JUPITER AS SEEN BY HUBBLE
-
-
- An image of Jupiter taken on May 18, 1994, by the Wide Field & Planetary
- Camera-2 (WFPC-2) in wide field mode aboard NASA's Hubble Space
- Telescope, when the giant planet was at a distance of 420 million miles (670
- million km) from Earth. This "true-color" picture was assembled from separate
- HST exposures in red, blue, and green light. Jupiter's rotation between
- exposures creates the blue and red fringe on either side of the disk. HST can
- resolve details in Jupiter's magnificent cloud belts and zones as small as 200
- miles (320 km) across (wide field mode). This detailed view is only surpassed
- by images from spacecraft that have traveled to Jupiter.
-
- The dark spot on the disk of Jupiter is the shadow of the inner moon Io. This
- volcanic moon appears as an orange and yellow disk just to the upper right of
- the shadow. Though Io is approximately the size of Earth's Moon (but 2,000
- times farther away), HST can resolve surface details.
