NASA’s Juno mission captured this look at Jupiter’s tumultuous northern regions during the spacecraft’s close approach to the planet on Feb. 17, 2020.

Notable features in this view are the long, thin bands that run through the center of the image from top to bottom. Juno has observed these long streaks since its first close pass by Jupiter in 2016. The streaks are layers of haze particles that float above the underlying cloud features. Scientists don’t yet know exactly what these hazes are made of or how they form. Two jet streams in Jupiter’s atmosphere flank either side of the region where the narrow bands of haze typically appear, and some researchers speculate those jet streams may influence the formation of the high hazes.

This JunoCam image was processed by citizen scientist Gerald Eichstädt. It was taken on Feb. 17, 2020, at12:29 p.m. EST, as the Juno spacecraft performed its 25th close flyby of Jupiter. At the time the image was taken, the spacecraft was about 15,610 miles (25,120 kilometers) from the planet’s cloud tops at a latitude of about 71 degrees North.

2020年2月17日,美国国家航空航天局的朱诺号探测器在接近木星的过程中捕捉到了这张木星北部地区的照片。

此视图中的显着特征是从顶部到底部贯穿图像中心的细长条纹。自2016年首次近距离掠过木星以来,朱诺号一直在观察这些长长的条纹。这些条纹是漂浮在下层云层之上的一层薄雾颗粒。科学家们还不完全知道这些薄雾是由什么构成或如何形成的。木星大气层的喷流常出现在薄雾带区域的两侧,一些研究人员推测这些喷射流可能会影响高空雾的形成。

这张JunoCam图像是由公民科学家Gerald Eichstadt处理的。这张照片拍摄于2020年2月17日美国东部时间下午12点29分,当时朱诺号宇宙飞船正在对木星进行第25次近距离飞越。在拍摄这张照片的时候,宇宙飞船距离火星层顶约15610英里(25120公里),纬度约为北纬71度。
