NASA's Cassini spacecraft sent back more jaw-dropping photos of Saturn earlier this month.
The images show scenes from high above Saturn’s northern hemisphere, including one of the planet’s strange hexagon-shaped storm. Each side of the hexagon is about as wide as Earth. A circular storm lies at the center, at the planet's north pole.
The hexagon is actually a current of air in Saturn's upper atmosphere, similar to Earth's jet streams, according to meteorologist Eric Berger of ARS Technica. It has winds estimated at 200 mph.
