The Great Red Spot of Jupiter SHRINKING ~ A storm that's been raging for over 300 years, it's three times the size of the entire Earth. NASA's recent Hubble Space Telescope observations confirm the Great Red Spot now is approximately 10,250 miles across, less than half the size of some historical measurements. Hubble's images over a span of decades show that the Great Red Spot is SHRINKING. NASA's Juno spacecraft is hurtling toward Jupiter now, due to reach the giant planet in July 2016…

At about 89,000 miles in diameter, Jupiter could swallow 1,000 Earths. It is the largest planet in the solar system and perhaps the most majestic. Vibrant bands of clouds carried by winds that can exceed 400 mph continuously circle the planet's atmosphere. Such winds sustain spinning anticyclones like the Great Red Spot -- a raging storm three and a half times the size of Earth located in Jupiter’s southern hemisphere.
Jupiter's trademark Great Red Spot - a swirling anticyclonic storm feature larger than Earth has shrunken to the smallest size ever measured. Astronomers have followed this downsizing since the 1930s. Image released May 15, 2014. NASA/ ESA/A. Simon
