The most volcanically active place in our solar system is one of Jupiter's 67-ish moons, Io. Its insides are incessantly pulled apart, ravaged, and heated by the mighty gravitational pulls of both Jupiter and its moons. Using a powerful telescope, scientists spotted an 8,300 square mile lake (bright yellow dot in the center-ish) on Io's surface – that's larger than Lake Ontario. Also, you'll notice that another of Jupiter's famous moons, Europa, makes an epic, if not slightly rude, photobomb.
