The Red Spot is a 10,000 mile wide storm that is going on in Jupiter. Consider: a category 5 hurricane in Earth can reach 157 miles per hour or more, and can flatten entire states. The Red Spot’s wind speeds can reach **268** MPH. That’s a lot of kinetic energy in the wind, which translates into a lot of heat energy that can be detected by infrared cameras.
