THE NEW WORLDS

Bevan M. French

King of the planets.
Giant Jupiter, with its Red Spot and banded, turbulent atmosphere, looms awesomely behind two of its moons in this view taken by the Voyager 1 spacecraft from about 20 million kilometers (12 million miles) away. The moons, each about the size of Earth's Moon, are dwarfed by the planet, which is large enough to contain more than a thousand Earths. Even at this distance, details ofJupiter's turbulent atmosphere are visible. Io, the moon at the left, is in front of Jupiter's Red Spot. This moon's orange color may be due to sulfur compounds erupted from its active volcanoes, discovered as Voyager flew past. Europa (at right) is a whitish moon. Its surface is probably a thick icy crust overlying a rocky core.
