About This Image
The Great Red Spot is a vast storm system on Jupiter. It spins like a cyclone, with speeds reaching 270 miles per hour (430 km/h). The storm, which is twice the size of the Earth, was first seen when 17th century astronomers turned their telescopes on the planet. More than 300 years later, it's still going strong.Learn more on the Hubble Heritage website Get supporting picture information including original images, caption and facts, and astronomer biographies.
