   Explanation: A bright storm head with a long turbulent wake swims
   across Jupiter in these sharp telescopic images of the Solar System's
   ruling gas giant. Captured on August 26, 28, and September 1 (left to
   right) the storm approximately doubles in length during that period.
   Stretching along the jetstream of the planet's North Temperate Belt it
   travels eastward in successive frames, passing the Great Red Spot and
   whitish Oval BA, famous storms in Jupiter's southern hemisphere.
   Galilean moons Callisto and Io are caught in the middle frame. In fact,
   telescopic skygazers following Jupiter in planet Earth's night have
   reported dramatic fast moving storm outbreaks over the past few weeks
   in Jupiter's North Temperate Belt.
