astroengine writes: Jupiter's Big Red Spot is the largest example of a long-lived storm in the solar system, but now it has some pretty stiff competition in another star system. However, this "exo-storm" hasn't been spied on another gas giant, it's been spotted in the uppermost layers of a cool, small "failed star," or brown dwarf. Using three NASA space telescopes, new research published in The Astrophysical Journal has found that this spot isn't a starspot, but a bona fide storm that has more in common with Jupiter's famous cyclone. So is this really a failed star? Or is is an "overachieving planet"?
