探测器“朱诺号”发现木星上复杂的旋涡风暴

木星上的一些风暴极其复杂。目前正在绕木星轨道飞行的NASA“朱诺号”航天器摄下这个漩涡风暴系统。这幅影像横跨约30000公里，因此这个风暴系统的宽度几乎与地球相当。这个扰动呈逆时针方向旋转，其云型主要是由氨冰组成的浅色上升气流构成 。这些稀薄的木星大气层位于木星最外部，甚至向右投射出清晰可辨的阴影。未来几年中，木星探测器“朱诺号”将会继续绕木星飞行，并返回数据，以便帮助我们更好地理解木星的大气水分含量，以及迷人的云层之下木星表面是否为固体。

Juno Spots a Complex Storm on Jupiter

Explanation: Some storms on Jupiter are quite complex. The swirling storm was captured late last month by the NASA's robotic Juno spacecraft currently orbiting the Solar System's largest planet. The featured image spans about 30,000 kilometers, making this storm system just about as wide as planet Earth. The disturbance rotates counter-clockwise and shows a cloud pattern that includes light-colored updrafts thought to be composed predominantly of ammonia ice. These light clouds are the highest up and even cast discernable shadows toward the right. Juno will continue to orbit and probe Jupiter over the next few years as it tries to return data that help us to better understand Jupiter's atmospheric water abundance and if the planet has a solid surface underneath these fascinating clouds.
