Explanation:
The strangest moon in the Solar System is bright yellow. This picture, an
attempt to show how Io would appear in the "true colors" perceptible
to the average human eye, was taken in 1999 July by the Galileo spacecraft that
orbited Jupiter from 1995 to 2003. Io's colors derive from sulfur and molten
silicate rock. The unusual surface of Io is kept very young by its system of
active volcanoes. The intense tidal gravity of Jupiter stretches Io and damps
wobbles caused by Jupiter's other Galilean moons. The resulting friction
greatly heats Io's interior, causing molten rock to explode through the
surface. Io's volcanoes are so active that they are effectively turning the
whole moon inside out. Some of Io's volcanic lava is so hot it glows in the
dark.
