1. Jupiter's Great Red Spot is a storm that lasts centuries: Prior to Voyager, the Great Red Spot was thought to be a solid feature on Jupiter. Voyager revealed it to be a massive, swirling storm, larger than Earth, that has raged for hundreds of years. This discovery revolutionized our understanding of Jovian weather patterns.
2. Volcanic activity on Io: Voyager 1 discovered active volcanoes erupting on Jupiter's moon Io. This was the first time active volcanism was observed on a celestial body other than Earth, revealing Io's unique geological activity fueled by Jupiter's gravitational pull.
3. Complex rings around Saturn: While we knew Saturn had rings, Voyager revealed their incredible complexity. Voyager revealed the rings are comprised of countless smaller ringlets, each with unique properties, and also discovered faint, previously unknown rings. These discoveries significantly increased our understanding of Saturn's ring system and its formation.
Bonus: The Voyager probes also provided stunning images of all the outer planets and their moons, revolutionizing our understanding of these distant worlds.
