NASA telescopes detect Jupiter-like storm on small, cool star

10 December 2015 Astronomy Now

Astronomers using data from NASA’s Spitzer and Kepler space telescopes have discovered what appears to be a Jupiter-sized star with a colossal, cloudy storm with a diameter that could hold three Earths. The storm rotates around the L-dwarf star known as W1906+40 about every 9 hours and has lasted at least two years, probably longer.
