While volcanos and volcanism on Earth can be amazingly spectacular, it can be unbelievably, super duper amazingly spectacular on other planets or moons as well. The image below is of Jupiter’s moon Io, which is one of the 4 large moons called Galilean satellites (so called because Galileo was the first to spot them). Io is the most volcanically active body in our solar system. So if you want to see some eruptions, that’s the place to go. The images were taken by NASA’s Galileo spacecraft in 1996. Click the image below for the full gallery of 14 images.
