The Great Red Spot on Jupiter
The Great Red Spot on Jupiter is a massive, persistent storm located in the planet’s southern hemisphere. It is larger than Earth and has been raging for at least 350 years. Characterized by its reddish hue and oval shape, the storm features powerful winds and turbulent clouds. Scientists believe it is a high-pressure region in Jupiter’s atmosphere, making it one of the most recognizable and iconic features in the solar system.

❓ Frequently Asked Questions
What is the Great Red Spot on Jupiter?
A giant, long‑lasting storm in Jupiter’s atmosphere — an anticyclone that’s bigger than Earth.
How big is it and how long has it lasted?
It spans about 1.3 Earth diameters (roughly 15,000–20,000 km across). It has been observed for more than two centuries and likely existed longer.
Why is it red?
Its red color is thought to come from complex chemical compounds formed by sunlight-driven reactions in Jupiter’s upper atmosphere; the exact mix isn’t fully known.
Will it disappear or keep changing?
The spot is slowly shrinking over time but remains enormous and long‑lived; winds along its edge are extremely fast, and changes happen gradually.
