NASA announced this week that its Cassini spacecraft has managed to capture a first-of-its-kind film of the monstrous jet stream roiling at Saturns north pole. The short GIF, using color filters, shows currents of air moving at 200 miles-per-hour in whats known as the hexagon, a system unique to Saturn measuring about 20,000 miles across the planets surface. According to NASA, theres no weather system in the solar system like it — and it has probably been active for decades, if not longer. The hexagon is just a current of air, and weather features out there that share similarities to this are notoriously turbulent and unstable, said Andrew Ingersoll, a Cassini imaging team member affiliated with the mission.
