Cyclones at the north pole of Jupiter appear as swirls of striking colors in this extreme false color rendering of an image from NASA’s Juno mission. The huge, persistent cyclone found at Jupiter’s north pole is visible at the center of the image, encircled by smaller cyclones that range in size from 2,500 to 2,900 miles (4,000 to 4,600 kilometers). Together, this pattern of storms covers an area that would dwarf the Earth.

The color choices in this image reveal both the beauty of Jupiter and the subtle details present in Jupiter’s dynamic cloud structure. Each new observation that Juno provides of Jupiter’s atmosphere complements computer simulations and helps further refine our understanding of how the storms evolve over time.

The Juno mission provided the first clear views of Jupiter’s polar regions. Juno’s Jovian InfraRed Auroral Mapper (JIRAM) instrument has also mapped this area, as well as a similar pattern of storms at the planet’s south pole.

Citizen scientist Gerald Eichstädt made this composite image using data obtained by the JunoCam instrument during four of the Juno spacecraft’s close passes by Jupiter, which took place between Feb. 17, 2020, and July 25, 2020. The greatly exaggerated color is partially a result of combining many individual images to create this view.

NASA朱诺号拍摄的这张图片的极端虚假色彩渲染中,木星北极的旋风以惊人的色彩漩涡出现。在图像的中心可以看到木星北极发现的巨、持续的气旋,周围环绕着较小的气旋,大小从2500英里到2900英里(4000到4600公里)不等。总的来说,这种风暴模式覆盖的区域会让地球相形见绌。

这张照片的颜色选择既展示了木星的美丽,也展示了木星动态结构中微妙的细节。朱诺号对木星大气的每一次新观测都是对计算机模拟的补充,并有助于进一步完善我们对风暴如何随时间演变的理解。

朱诺号任务首次清晰地观测到了木星的两极区域。朱诺号的木星红外极光制图仪(JIRAM)也绘制了这一区域,以及木星南极类似的风暴模式。

公民科学家Gerald Eichstädt利用JunoCam仪器在朱诺号飞船四次近距离飞越木星期间(即2020年2月17日至7月25日)获得的数据制作了这张合成图像。这种极度夸张的色彩部分是由于结合了许多单独的图像来创建这个视图的结果。
