What geometric cloud pattern was discovered swirling persistently at the north pole of Saturn by the Voyager and Cassini missions?
Answer and explanation
Correct answer: C. Hexagon
- Step 1: Saturn's northern polar atmosphere features a striking, persistent six-sided jet stream wave pattern first identified in Voyager imagery from 1981.
- Step 2: Each side of the hexagon is approximately 14,500 kilometers long (wider than Earth), maintained by deep atmospheric zonal winds rotating at roughly 320 km/h.
Answer
Hexagon
Why not the others: 'Pentagon' Atmospheric simulations produce various polygon modes, but Saturn's observed north polar jet stream is a six-sided hexagon; 'Octagon' An eight-sided octagon does not match Saturn's polar jet stream geometry; 'Circle' Typical cyclonic storms are circular, but Saturn's unique polar jet stream maintains a stationary six-sided hexagonal wave.
