Take A Look at Jupiter's Hot Moon Io in True Color

One of the strangest moon in the solar system, Io is Jupiter's moon and it is bright yellow in color. The reason for the bright yellow color is sulfur and molten silicate rocks. Io has highly active volcanoes and this is the reason the surface of Io is kept young.

Intense tidal gravity from mother planet Jupiter and also the bigger moons of Jupiter stretches Io so hard, Io wobbles greatly and as a result it get lot of heat from friction and causing molten rocks to explode through the surface. Io's volcanic lava is sometimes so hot, it glows in the dark.

 

The above image is taken by Galileo spacecraft in 1999, that orbited Jupiter from 1995 to 2003. This is how Io would look like to normal human eye (true color image). Click the image to see the full size image.
