Jupiter’s iconic spot

There are few things in the Solar System more iconic then Jupiter's Great Red Spot, that swirling vortex staring out from the giant planet like a huge eye. Ever since Cassini (or was it Hooke?) first spotted it back in the late 17th century, it's been an object of fascination for astronomers and amateur stargazers alike. New research shows the spot is not only shrinking, it's speeding up — but why? What's going on? What even is this thing anyway? Emily's got all the answers.
