Saturn Hexagon Mystifies Scientists
March 27, 2007 — A long-lived double hexagon formed in the clouds.
The two six-sided features — one inside the other — are in stark contrast to the hurricane-like vortex that has been observed at the ringed planet's south pole. Both poles have been imaged by NASA's orbiting Cassini spacecraft.
"We haven't seen a (geometric) feature like this anywhere else on any other planet," said Cassini scientist Kevin Baines of the NASA's Jet Propulsion Laboratory. "It's unbelievable."
