说明: 木星的云会怎么运动呢?为了找出答案,美国航太总署的朱诺号太空船,在最近一次掠过 木星时所拍摄的影像,经过特别分析,并使用数位外插技术把它们製成一部缩时影片。这部8秒长的缩时影片,粗略呈现了木星云层在29小时期间的运动,其中,拍摄时间相隔短短9分钟的二张照片之间的影像,皆是来自数位外插。这个相当抽象的成品,看起来有点像迷幻佩兹利涡旋梦境。以科学的观点来看,圆形的风暴系统有迴旋打转的倾向,而云带和云区 则看似在流动。木星云层的运动特性,其实并不令人意外,因为在先前拍摄的木星缩时影片里,就看过了这些特徵,只不过从没这么细緻而已。这部主题影片所呈现的区域,大约是大红斑面积的4倍。在朱诺号的诸多成果里,还包括证实木星的天气现象很意外的可以深入到云层之下

Explanation: How do Jupiter's clouds move? To help find out, images taken with NASA's Juno spacecraft during its last pass near Jupiter have been analyzed and digitally extrapolated into a time-lapse video. The eight-second time-lapse video, digitally extrapolated between two images taken only nine minutes apart, estimates how Jupiter's clouds move over 29 hours. Abstractly, the result appears something like a psychedelic paisley dream.Scientifically, however, the computer animation shows that circular storms tend to swirl, while bands and zones appear to flow. This overall motion is not surprising and has been seen on time-lapse videos of Jupiter before, although never in this detail. The featured region spans about four times the area of Jupiter's Great Red Spot.Results from Juno are showing, unexpectedly, that Jupiter's weather phenomena can extend deep below its cloud tops.
