A Great Cold Spot comparable in scale to Jupiter's famous Great Red Spot (24,000 km west-east and 12,000 km north-south) has been found on the planet. The phenomenon, only recently observed, may have existed for thousands of years, however, this is the first direct evidence of a sustained weather system generated by polar aurorae and opens possibility on other planets.
