As Seen On COSMOS: Jupiter’s Great Red Spot As Captured By Voyager 1
Jupiter’s hallmark Great Red Spot, a persistent anticyclonic storm which has persisted for hundreds of years, is shrinking in size according to measurements taken by NASA. According to historical measurements the most powerful storm in the Solar System is less than half the size it was estimated to be in the late 1800s. Although it is still large enough to swallow Earth whole, measuring 10,250 miles across today. In February 1979, when this photo was taken by Voyager 1 the Great Red Spot measured 14,500 miles across.
