Voyage to Jupiter
Jupiter looms in the sky above its moon Io. An erupting volcano on Io's horizon sends a plume hundreds of miles into space. The eruptions mottle Io's surface with multicolored deposits of sulfur and lakes of lava.
Jupiter's beauty masks turbulence beyond imagination. Between its colorful bands of clouds swirl immense hurricane-like storms. One, the Great Red Spot, could swallow 2 Earths. Beneath the clouds, an ocean of mostly hydrogen and helium extends to Jupiter's core.
A Solar System in Miniature
The largest planet, Jupiter reigns over at least 67 moons and a delicate system of rings. Four moons--Io, Europa, Ganymede, and Callisto--are larger than Pluto. Ganymede is larger than Mercury. Europa has an icy surface that may conceal an ocean with more water than all the oceans on Earth--a promising place to look for life.
Walk to Saturn about 98 steps
Walk to Asteroids and Comets about 55 steps
