Why does Jupiter have a big red spot?

Jupiter’s rapid spin, its hurricane-force winds, and the chemical composition of its atmosphere create colorful cloud bands that encircle the planet. One of these bands contains a hurricane large enough to span three Earths. This Great Red Spot has been raging for centuries.

The Great Red Spot is a giant, spinning storm in Jupiter’s atmosphere. Jupiter’s Great Red Spot is more than twice the size of Earth! Winds inside this storm reach speeds of about 270 miles per hour. Nobody knows when the Great Red Spot first appeared on Jupiter, but it has been seen on Jupiter ever since people started looking through telescopes about 400 years ago.
