The last of Jupiter's 4 important moons or at least important at this writing. Io's scientific story begins with the gigantic pull of Jupiter and the opposite pull by Europa and Ganymede which results in Io's surface heaving up and down like an ocean tide. This is one explanation of Io's volcanoes hurling and exploding sulphurous material at an amazing force. Io is one active moon which rivals Earth in volcanoes. On its pizza shape surface there is sulphurous snow and ice and huge lava beds and below all that might be a sulphur ocean?
The myth once again has Jupiter as fooling this young heart of Io and once again Juno (his wife) seeking revenge with magic and such. This story even brings in Mercury all to keep the chaos going and going and going!
These small photos of Io were taken by the Galileo spacecraft and I added them as multiples because they looked so alone and perfect and together as a review of the icy and volcanic beauty.
Looking at Saturn now and I hope to change it up...another vantage point....another interpretation...something but not sure what or how?
