Weizmann Institute of Science research uncovers the internal mechanisms driving storms toward the poles

The south pole of Jupiter is seen from an altitude of 32,000 miles (52,000 kilometers) in this enhanced color mosaic of images from NASA's JunoCam. Cyclones up to 600 miles wide (1,000 km) are visible. Credit: NASA/JPL-Caltech/SwRI/MSSS/Betsy Asher Hall/Gervasio Robles SCOTT BOLTON – 3

A new mathematical formula can reveal how fast a planet is rotating

Image from the Voyager II flyby of Neptune in August 1989 (NASA). In the middle is the Great Dark Spot, accompanied by bright, white clouds that undergo rapid changes in appearance. To the south of the Great Dark Spot is the bright feature that Voyager scientists nicknamed "Scooter." Still farther south is the feature called "Dark Spot 2," which has a bright core. As each feature moves eastward at a different velocity, they are rarely aligned this way. Wind velocities near the equator are westward, reaching
