Why does Jupiter have the Great Red Spot?
Show answer & explanation
Answer: Giant storm system persisting
Iron oxide like Mars — Wrong. Jupiter is gaseous (hydrogen, helium). The red color likely comes from complex organic compounds created by solar radiation, not iron oxide.
Giant storm system persisting ✓ — Correct! The Great Red Spot is a massive anticyclonic storm—been observed for ~350+ years! It's ~2x Earth's diameter but shrinking. Storms on gas giants can persist far longer than on Earth because there's no land to disrupt them. The red color may be from phosphorus or sulfur compounds brought up from deeper atmospheric layers!
Shadow from Jupiter's moons — Wrong. Moon shadows are temporary. The Great Red Spot is a persistent storm feature in Jupiter's atmosphere visible for centuries.
