Meanwhile, back on Saturn...

Curious:

A mysterious giant hexagon lies above Saturn's north pole, captured by cameras on Nasa's Cassini Orbiter.

Spanning 25,000km - equivalent to the width of two planet Earths - the bizarre geometric feature appears to remain virtually still in the atmosphere as clouds swirl around it.

UPDATE: via the Speculist, a video and scale info: 4 earths would fit inside the hexagon.
