ok, so you know how earth has north and south? that is because of a magnetosphere, basically a magnetic field over the entire earth, so Uranus has this too and when solar gasses build up too much and put too much pressure on the planet it opens its magnetosphere to let the gasses/winds out. source in case I was confusing: http://www.ibtimes.com/uranus-opens-closes-every-day-let-out-planets-solar-wind-study-finds-2558234
Scientists had such a field day naming this wonderful planet xD
Welcome back btw
