Like the speed of an advancing race car driver, the winds in the outermost
“lane” of Jupiter’s Great Red Spot are accelerating ... a discovery only made
possible by NASA’s Hubble Space Telescope, which has monitored the planet
for more than a decade.
Researchers analyzing Hubble’s regular “storm reports” found that the
average wind speed just within the boundaries of the storm, known as a
high-speed ring, has increased by up to 8 percent from 2009 to 2020. In
contrast, the winds near the red spot’s innermost region are moving
significantly more slowly, like someone cruising lazily on a sunny Sunday
afternoon.
