Jupiter's Winds

 From Space:

A decade of Jovian storm-chasing paid off for the Hubble Space Telescope. The long-running telescope has been studying the Great Red Spot — a major storm on Jupiter — that is shrinking for mysterious reasons. Alongside that, researchers just uncovered huge changes in wind speeds within the massive storm. Jupiter takes 12 Earth years to orbit the sun. During the Jovian year between 2009 and 2020, Hubble found, winds in the outer ring of the Great Red Spot increased by up to 8%. While the wind speed varied depending on when Hubble was looking at the storm, the telescope did track long-term increases in the rotation speed of the outer ring. (Read more.)
