Saturn’s North Polar Hexagon


by Txchnologist Staff

The image above (larger here) shows a phenomenal cloud pattern that sits over Saturn’s north polar region. The hexagon, which was first seen more than 20 years ago by the passing pair of Voyager spacecraft, was recorded again by the international Cassini spacecraft mission on Nov. 27, 2012.

The many smaller dots in and around the 15,000-mile-wide hexagonal vortex are smaller storms. This image was taken with Cassini’s wide-angle camera using a spectral filter sensitive to wavelengths of near-infrared light.

This animated image shows Saturn’s north polar hexagonal vortex in motion at night on the planet. Image courtesy NASA/JPL/University of Arizona.
