​Saturn's Streaming Hexagon

Cassini finished its initial four-year mission to Saturn in 2008 and is now on its second extended mission, called Cassini Solstice. 

The Solstice mission is named after the Saturnian summer solstice in May, 2017. That will mark the beginning of the planet's summer, when the northern hemisphere and its unusual hexagonal jet stream is on full display. 

In this image, scientists assigned colors to different parts of the ultraviolet spectrum.
