Jupiter's Great Red Spot is a storm bigger than Earth that has raged for centuries.

The Great Red Spot is a giant anticyclonic storm in Jupiter’s atmosphere, historically large enough that Earth could comfortably fit inside it, though the storm has been shrinking in recent decades. Wind speeds at its edges can exceed 400 kilometers per hour.

Continuous telescopic observations of the storm date back to at least the 1830s, and some astronomers believe records may extend to sightings from the 17th century, making it one of the longest-lived storms known anywhere in the solar system. Unlike hurricanes on Earth, which weaken once they move over land and are cut off from warm ocean water, the Great Red Spot has no landmass to disrupt it and draws its energy from Jupiter’s turbulent, fast-rotating atmosphere.
