Enormous, Glassy Lava Lake On Jupiter’s Io Revealed By NASA In Incredible Animation

NASA’s Juno has recently performed some extremely close flybys of Io, the innermost of the four Galilean moons of Jupiter. The natural satellite is the most geologically active body in the Solar System, featuring 400 active volcanoes. Members of the Juno team have used data from recent encounters to reconstruct some intriguing features on the surface of Io.

Meet Loki Patera, the largest volcanic depression on Io. It is an enormous lava lake. On Earth, it would be the 13th largest lake in the world. In the middle of the lake, there is an island rising from the surface. That in itself is extreme but it’s not even the weirdest feature of the lake.
