Saturn and its largest moon Titan again posed the spacecraft "Cassini".
Eight years ago, when the station just arrived to the places in the northern hemisphere of Saturn was winter and it was a sky-blue. Now comes the winter in the southern part of the planet — and the picture changes: the blue fades in the northern hemisphere, gradually painting the South.
On the other three images seen recently discovered southern polar vortex in the atmosphere of Titan. Camera "Cassini", operating in the visible part of the spectrum, there is observed accumulation of yellowish mist from March 27, and May 22 infrared spectrometer recorded concentrations of clouds around the south pole. After orbiting satellite, on 27 June, "Cassini" sent a great picture and video, which showed that the vortex rotates faster than the moon itself. Photographs presented here were obtained in May, June and July.
Some of these pictures were made possible only thanks to the new orbits "Cassini", which allow you to see the poles of Saturn and its moons.
Here the "Cassini" is looking at the night side of Titan, observing the scattering of sunlight on the periphery of the moon's atmosphere. This mosaic of photographs taken June 6, 2012 with the approximate distance of 216 thousand kilometers.
