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.

说明: 在这幅以太阳系最大气态巨行星为主题的清晰望远镜影像里，一个带着长长湍动迹流的明亮风暴前沿，于木星的表面游动。如这些分别摄于8月26日、28日及9月1月（左到右）的照片所示，在这段期间，风暴的长度大约加倍。这个沿木星北温带的喷射气流伸展之风暴，在这些接续拍摄的照片里明显向东游动，通过木星南半球著名的大红斑和泛白椭圆BA等风暴系统。中间的影格，同时也拍到2颗伽利略卫星─木卫四和木卫一。在过去的数星期之中，地球夜面用望远镜归踪木星的观星者，也报导木星的北温带出现高速移动的风暴系统。
