A recent photograph of the Saturn’s moon Titan taken by the NASA’s Cassini probe shows a vortex swirling on the south pole of the Saturn’s moon. This is leading the Astronomers to believe that winters are indeed approaching in the southern reaches of the Titan. The photograph was taken on June 27, and the storm completes one rotation in about 9 hours while the rotation period of the Titan is 16 days. Tony Del Genio who is a Cassini team member at NASA’s Goddard Institute for Space Studies in New York said in a public statement,
The structure inside the vortex is reminiscent of the open cellular convection that is often seen over Earth’s oceans. 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.
