The camera (at bottom) is on an arm thatswivels. To the left of the white main

antenna for sending data back to Earth,

you can see a gold disk; this is the coverfor an audio-visual recording of the sights

and sounds of Earth, included for the

remote possibility that some othercivilization might find the capsule

Jupiter

This processed color image

of Jupiter was produced in1990 by the U.S. Geological

Survey from a Voyager

image captured in 1979.The colors have been

enhanced to bring out detail.

Zones of light-colored,ascending clouds alternate

with bands of dark,

descending clouds. The

clouds travel around theplanet in alternating

eastward and westward

belts at speeds of up to 540kilometers per hour.

Tremendous storms as big

as Earthly continents surgearound the planet. The

Great Red Spot (oval shape

toward the lower-left) is anenormous anticyclonic storm

that drifts along its belt,

eventually circling the entireplanet.
