This photo was captured 1.6 million miles above Saturn by the Cassini spacecraft on November 23rd, last year. The shot of Saturn's polar vortex was taken during a huge storm.
The hexagonal vortex is about 20,000 miles (30,000 km) across and is a jet stream made up of 200 mph winds (322 km/h) surrounding a huge storm, NASA officials have said. Scientists have not found another weather feature exactly like this anywhere in the solar system, space agency officials said.
