The Great Red Spot, a storm larger than the Earth and powerful enough to tear apart smaller storms that get drawn into it, is one of the most recognizable features in Jupiter’s atmosphere and the entire solar system. The counterclockwise-moving storm, an anticyclone, boasts wind speeds as high as 300 miles per hour. This prominent feature, observed since 1830, and possibly as far back as the 1660s, has long been a source of great fascination and scientific study.
