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.

Io, as they used to say on the Johnny Carson show.

Cheese ball, mmmmmmmmmm:
It kind of looks like a faded out old superball I used to have as kid, right down to the pock marks from the dogs teeth!

If he owned Io and hell. He’d rent Io out - and live in hell.

That photo is along the lines of what came to mind when seeing the 'real color' image of Io;

Here's Io in the 1980 NASA publication, Voyage to Jupiter. I suppose it's a fairly subtle adjustment, in technical terms, to make the transition from this red-orange image to the yellow image of the APOD. I think it's bound to be a problematical question how it would actually appear to a person somehow situated to observe it directly.
Anyway, I'll always think of it as "The Pizza Planet" !

It probably smells like eggs. Sulfur is stinky.

Old McDonald had a moon, Eee-i, eee, Io.
I hate it when they burn the edges of the crust like that. :-)
Some of Io's volcanic lava is so hot it glows in the dark.
Huh? Umm, it's lava. Doesn't all lava glow? Or am I missing something?

Huh, I knew I recognized that!
Thank you for the ping, Mr. Civilizations.
It’s interesting to see what tidal forces can do when there are enough moons
involved to generate friction, not to forget Jupiter itself.
Nice picture as well.
Lava can be either hot or cold. The piece is written poorly, IMO.
