NASA's Hubble Telescope captures Jupiter's Great Red Spot acting like a "giant stress ball"

The Hubble Telescope capturing the Great Red Spot.

Astronomers have been observing Jupiter’s legendary Great Red Spot (GRS), "an anticyclone large enough to swallow Earth", for the last 150 years. Yet despite the longevity of the observations of this long-lived enormous storm system, there are always new surprises. 

The Great Red Spot is an anticyclone, "a long lasting area of high pressure on Jupiter creating a persistent storm," according to Space.com. It is the largest storm in our solar system, and at 10,159 miles / 16,350km wide, it’s about 1.3 times the width of the Earth (7,918 miles / 12,740 km).
