This week, NASA’s Juno spacecraft performed its 7th close flyby of Jupiter, which provided us with the best glimpse yet of the planet’s iconic Great Red Spot. At the time this image was taken, the spacecraft was about 6,130 miles (9,866 kilometers) above the tops of Jupiter’s clouds. Jupiter's Great Red Spot is actually a massive storm system that has been raging for an estimated 350 years. Measuring in at 10,159 miles (16,350 kilometers) in width, the storm is 1.3 times as wide as Earth! Astronomers have been studying the spot since 1830, and modern imaging has suggested the Great Red Spot appears to be slowly shrinking. “For hundreds of years scientists have been observing, wondering and theorizing about Jupiter’s Great Red Spot,” said Scott Bolton, Juno principal investigator from the Southwest Research Institute in San Antonio. “Now we have the best pictures ever of this iconic storm. It will take us some time to analyze all the data from not only JunoCam, but Juno’s eight science instruments, to shed some new light on the past, present and future of the Great Red Spot.” #juno #jupiter #greatredspot #nasa #amnh
