Something’s going on over the south pole of Titan. A vortex of haze appears to be forming, but no one can explain why. This natural-color image shows the light-colored vortex which was found on images taken last month when the Cassini spacecraft flew by the largest of Saturn’s moons. Cassini is now able to see the southern vortex because its orbit around Saturn was recently boosted out of the plane of the orbits of the rings and moons. Clues about the odd feature are being gathered, but it will soon be winter in the southern hemisphere of Titan. The vortex, if it lasts, will be in darkness for the next few years.
