NASA’s Hubble detects Jupiter’s Great Red Spot storm is speeding up – CNET [CNET]

The Great Red Spot’s winds whip around counterclockwise, hitting speeds of over 400 mph (644 km/h). The storm alone is bigger than Earth. NASA put together a video showing the wind movement. 

Hubble has been monitoring Jupiter for years. The wind speed change might not have been spotted if it weren’t for the telescope’s keen eye. 

“We’re talking about such a small change that if you didn’t have eleven years of Hubble data, we wouldn’t know it happened,” planetary scientist Amy Simon said in a NASA statement on Monday. Simon is a co-author of a study on the wind published in the journal Geophysical Research Letters (PDF link),
