Jupiter's Great Red Spot is apparently also red hot: The highest temperatures ever observed on the planet were recently detected in the region above the ginormous storm.

The Great Red Spot (GRS) is a massive storm about twice the diameter of Earth that lies in lowest layer of Jupiter's atmosphere. About 497 miles (800 kilometers) above this humongous storm, astronomers measured temperatures reaching about 700 degrees Fahrenheit (about 370 degrees Celsius) higher than normal, James O'Donoghue, lead author of the new study and a research scientist with Boston University's (BU) Center for Space Physics, told Space.com.

Yes, apparently there are two types of "turbulent energy waves" in the GRS that collide and create the extra heat in the upper atmosphere. Here to hoping Juno can gather more pertinent data.

Some 4K Hubble video released in the fall of 2015 confirms the Great Red Spot is getting smaller and losing a lot of its elliptical nature. Some current GRS viewing times (Baton Rouge specific) should be on the Forum within twenty-four hours.
