这些大椭圆是什么，在哪里？这是上个月由美国宇航局朱诺号宇宙飞船拍摄的木星上旋转的风暴云。一般来说，较高的云颜色较浅，可见的最轻的云是点缀在较低椭圆形的相对较小的云。然而，在直径50公里的情况下，即使是这些轻云也不小。它们是如此之高，以至于在下面旋转的椭圆形上投下了阴影。特征图像经过处理以增强颜色和对比度。大椭圆通常是高压区域，跨度超过1000公里，可以持续数年。木星上最大的椭圆形是大红斑（不在图中），它已经持续了至少数百年。利用朱诺号的图像研究木星的云动力学，可以更好地了解地球上危险的台风和飓风。在Facebook， Instagram, Podcast， Reddit或Twitter上关注APOD英文版

What and where are these large ovals? They are rotating storm clouds on Jupiter imaged last month by NASA's Juno spacecraft. In general, higher clouds are lighter in color, and the lightest clouds visible are the relatively small clouds that dot the lower oval. At 50 kilometers across, however, even these light clouds are not small. They are so high up that they cast shadows on the swirling oval below. The featured image has been processed to enhance color and contrast. Large ovals are usually regions of high pressure that span over 1000 kilometers and can last for years. The largest oval on Jupiter is the Great Red Spot (not pictured), which has lasted for at least hundreds of years. Studying cloud dynamics on Jupiter with Juno images enables a better understanding of dangerous typhoons and hurricanes on Earth.
