看朱诺掠过木星。美国国家航空航天局的“朱诺”号机器人探测器将继续在其长达一个月的、高度拉长的轨道上运行，环绕太阳系最大的行星。这段精选视频来自近木星16号，这是朱诺号自2016年年中抵达木星以来第16次经过木星附近。每一个近木星经过木星云顶的一个略微不同的部分。这段色彩增强的视频是由朱诺相机拍摄的21张静止图像数码合成而成，延时达125倍。视频开始时，朱诺号从北方靠近，木星升起。当“朱诺”号到达距离木星最近的地方——距离木星云顶约3500公里——飞船捕捉到了这颗伟大行星的大量细节。“朱诺”号会经过环绕木星的亮区和暗带云层，以及许多漩涡状的圆形风暴，其中许多比地球上的飓风还要大。当朱诺号离开时，这片海豚状的云清晰可见。在近日点之后，木星向远处退去，现在显示出木星南部出现的不寻常的云。为了获得所需的科学数据，朱诺号俯冲到离木星很近的地方，以至于它的仪器暴露在非常高的辐射下。

Watch Juno zoom past Jupiter. NASA's robotic spacecraft Juno is continuing on its now month-long, highly-elongated orbits around our Solar System's largest planet. The featured video is from perijove 16, the sixteenth time that Juno passed near Jupiter since it arrived in mid-2016. Each perijove passes near a slightly different part of Jupiter's cloud tops. This color-enhanced video has been digitally composed from 21 JunoCam still images, resulting in a 125-fold time-lapse. 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 belts of clouds that circle the planet, as well as numerous swirling circular storms, many of which are larger than hurricanes on Earth. As Juno moves away, the remarkable dolphin-shaped cloud is visible. After the perijove, Jupiter recedes into the distance, now 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.
