LOS ANGELES TIMES - Jupiter moon Io's volcanic face could mask 'living' fossil, Apr 06, 2013

"Like the offset eyes on a Picasso portrait, the volcanoes on Jupiter’s moon Io seem to be strangely shifted, according to a study by NASA and ESA scientists. Io’s clustered volcanoes seem to be lying 30 to 60 degrees eastward of where they were expected, according to a paper published this year in Earth and Planetary Science Letters. The study could shed light on the internal dynamics of Jupiter’s volcano-pocked moon. Io’s internal heat comes from the kneading it gets from Jupiter and its fellow moons. Jupiter’s massive gravity pulls on the planet, stretching it one way. Meanwhile, tugs from fellow moons Europa and Ganymede stretch it from another direction. As Io flexes, internal friction from all that distortion heats up the interior, leading to its iconic volcanoes."
