The giant storm has raged for centuries but is now smaller than ever recorded

Jupiter's Great Red Spot is a persistent high-pressure anticyclonic storm located south of the planetary equator. While historical observations from the 19th century indicated it was wide enough to swallow three Earths, modern space telescope imagery shows it has shrunk to roughly one Earth diameter.
