Jupiter’s Great Red Spot
The Great Red Spot on Jupiter is a massive storm (cyclone) measuring about 16,000 km in diameter. It is largest known storm in the solar system. It has been monitored since 1830 and has possibly existed for more than 350 years.
The winds in the storm are clocked at hundreds of km an hour around its outer edges. Little is known about the forces driving it. The spot appears as a deep, red orb surrounded by layers of pale yellow, orange and white. The storm is believed to have been shrinking in recent years.
