Saturn's hydrogen- and helium-rich atmosphere

The NASA/ESA/ASI Cassini spacecraft captured this view, which shows that Saturn's atmosphere is a dynamic place, filled with spots, ovals and swirling vortices and filaments of gas.

The image was taken with the Cassini wide-angle camera on 14 December 2004, at a distance of 595 000 kilometres from Saturn through a filter sensitive to wavelengths of infrared light centred at 939 nanometres. It has been highly processed to enhance details. The image scale is about 32 kilometres.
