Explanation: Big storms are different on Jupiter. On Earth, huge hurricanes and colossal cyclones are centered on regions of low pressure, but on Jupiter, it is the high-pressure, anti-cyclone storms that are the largest. On Earth, large storms can last weeks, but on Jupiter they can last years. On Earth, large storms can be as large as a country, but on Jupiter, large storms can be as large as planet Earth. Both types of storms are known to exhibit light ning. The featured image of Jupiter’s clouds was composed from images and data captured by the robotic Juno spacecraft as it swooped close to the massive planet in August 2020. A swirling white oval is visible nearby, while numerous smaller cloud swirls extend into the distance. On Jupiter, light-colored clouds are usually higher up than dark clouds. Despite their differences, studying storm clouds on distant Jupiter provides insights into storms and other weather patterns on familiar Earth.

说明: 木星上的大风暴颇有不同。在地球上，庞大的台风和巨大的气旋其中心为低压区，然而在木星上，最大型的风暴是高压反气旋。在地球上，大风暴可以持续数星期，但是在木星上，它们可以存续数年。在地球上，大风暴可以和国家一样大，而在木星上，大风暴可以和地球等大。不过，这两种类型的风暴都会产生闪电。这幅以木星云为主题的影像，是由朱诺号宇宙飞船在2020年8月俯冲接近这颗巨行星时，所取得的影像和数据组合而成。影像的近处可见到一个漩涡状的白椭圆云，而许多较小的漩涡云则绵延至远处。在木星上，浅色云通常比暗色云高。尽管它们之间有差异，然而研究遥远木星上的风暴云，会对洞察我们地球上的风暴和其他天气现象有所帮助。
