Poor Jupiter. It’s breaking out*.
The Great Red Spot is a vast, planet-sized hurricane that’s been blowing on Jupiter for hundreds of years. In 2006 it was joined by a smaller storm — though still thousands of miles across — called Oval BA (no relation).
The third storm (the smaller one in the middle left on the Hubble picture above) was a more normal whitish oval up until recently, when it suddenly turned red. It’s unclear why
colors of the storms indicate their chemical composition, and red usually means complex organic compounds
dredged up from deep beneath Jupiter’s cloud tops, or maybe the storm gained altitude, high enough that incoming solar ultraviolet light was able to reassemble the molecules into new ones
That means that if you could see this from the side, it would look like a bump, or a welt, or, well, a pimple
if transported to Earth, even that small spot would cover most of a hemisphere
