Explanation: Here comes Jupiter! NASA’s robotic spacecraft Juno is continuing on its highly-elongated orbits around our Solar System’s largest planet. The featured video is from perijove 11 in early 2018, the eleventh time Juno has passed near Jupiter since it arrived in mid-2016. This time-lapse, color-enhanced movie covers about four hours and morphs between 36 JunoCam images. The video begins with Jupiter rising as Juno approaches from the north. As Juno reaches its closest view — from about 3,500 kilometers over Jupiter’s cloud tops — the spacecraft captures the great planet in tremendous detail. Juno passes light zones and dark belt of clouds that circle the planet, as well as numerous swirling circular storms, many of which are larger than hurricanes on Earth. After the perijove, Jupiter recedes into the distance, then displaying the unusual clouds that appear over Jupiter’s south. To get desired science data, Juno swoops so close to Jupiter that its instruments are exposed to very high levels of radiation.

说明: 木星迎面而来。美国国家航空航天局的朱诺号太空船，持续在高度椭圆的轨道上绕行太阳系最大的行星。这部主题影片，摄于2018年初的近木轨道11（perijove 11），亦即自朱诺号在2016年中抵达木星之后，第11次掠过木星附近。这部色泽经过强化的缩时影片，制作自涵盖大约4小时期间的36张朱诺相机照片。在这部影片开头时，随着朱诺号从北方接近木星，木星也随之升起。当朱诺号航行到距离木星的云顶约3,500公里的最近点时，太空船拍下了这颗巨行星无比清晰的影像。朱诺号除了掠过环绕这颗行星的淡色区和暗带之外，也掠过难以数计的圆形涡旋风暴系统，其 中有许多大于地球上的台风。通过近木点之后，接着见到逐渐远去的木星南极附近之不寻常云系。为了取得所需要的科学数据，朱诺号得非常近距离掠过木星，以至于它的仪器会曝露在非常高辐射的环境里。
