观察我们太阳系最大的行星优雅的旋转。木星神秘大气的许多有趣的特征，包括暗带和亮带，都可以详细跟踪。仔细观察就会发现，不同的云层旋转速度略有不同。著名的大红斑一开始是看不见的，但很快就旋转进入视野。其他较小的风暴系统偶尔也会出现。像木星那么大，它的自转周期只有10个小时。相比之下，我们的小地球需要24小时才能完成一个旋转周期。这段高分辨率延时视频是本月早些时候在法国巴黎一所公寓阳台上用一台中型望远镜用五个晚上拍摄的。由于氢气和氦气是无色的，而这些元素构成了木星膨胀的大气的大部分，是什么微量元素创造了木星云的可见颜色仍然是一个研究课题。探索+拓展：APOD研究生研究职位开放

Observe the graceful twirl of our Solar System's largest planet. Many interesting features of Jupiter's enigmatic atmosphere, including dark belts and light zones, can be followed in detail. A careful inspection will reveal that different cloud layers rotate at slightly different speeds. The famous Great Red Spot is not visible at first -- but soon rotates into view. Other smaller storm systems occasionally appear. As large as Jupiter is, it rotates in only 10 hours. Our small Earth, by comparison, takes 24 hours to complete a spin cycle. The featured high-resolution time-lapse video was captured over five nights earlier this month by a mid-sized telescope on an apartment balcony in Paris, France. Since hydrogen and helium gas are colorless, and those elements compose most of Jupiter's expansive atmosphere, what trace elements create the observed colors of Jupiter's clouds remains a topic of research.
