Titan, one of Saturn’s most interesting moons, has yet another mystery: a giant vortex on it’s south pole. Cassini spotted the vortex on June 27th, 2012. There are similar phenomena that occur on Earth that are associated with the changing of the seasons, but this vortex is especially interesting because it extends very high into the atmosphere.
the structure inside the vortex is reminiscent of the open cellular convection that is often seen over Earth’s oceans,” said Tony Del Genio, a Cassini team member at NASA’s Goddard Institute for Space Studies, N.Y. “But unlike on Earth, where such layers are just above the surface, this one is at very high altitude, maybe a response of Titan’s stratosphere to seasonal cooling as southern winter approaches. But so soon in the game, we’re not sure.”
