木星喧嚣的云彩

这张令人惊叹的木星北半球风暴的图片是由美国宇航局的朱诺号飞船在近距离飞越这颗气态巨行星时拍摄的。在木星圆盘的右侧,可以看到一些在高空的明亮的白云。 “朱诺号”于2019年5月29日美国东部时间凌晨3点52分至凌晨4点03分拍摄了这四张用来产生这张彩色增强图的图片,当时“朱诺号”正在对木星进行第20次科学探测。在拍摄这些照片时,这艘宇宙飞船位于木星云层上方11,600英里(18,600公里)至5,400英里(8,600公里)之间,位于北纬59度至34度之间。 公民科学家凯文·M·吉尔利用宇宙飞船JunoCam成像仪的数据制作了这幅图像。公众可以通过https://missionjuno.swri.edu/junocam/processing浏览JunoCam的原始图像以及处理后的图像产品。 This stunning image of Jupiter’s stormy northern hemisphere was captured by NASA’s Juno spacecraft as it performed a close pass of the gas giant planet. Some bright-white clouds can be seen popping up to high altitudes on the right side of Jupiter’s disk. Juno took the four images used to produce this color-enhanced view on May 29, 2019, between 3:52 a.m. EDT and 4:03 a.m. EDT, as the spacecraft performed its 20th science pass of Jupiter. At the time the images were taken, the spacecraft was between 11,600 miles (18,600 kilometers) and 5,400 miles (8,600 kilometers) above Jupiter’s cloud tops, above a northern latitude spanning from about 59 to 34 degrees. Citizen scientist Kevin M. Gill created this image using data from…

木星的深渊

木星的深渊

2019 June 10 木星的深渊 图像来源:NASA, Juno, SwRI, MSSS; Processing & License: Gerald Eichstädt & Sean Doran 说明:木星上的那个黑点是什么?没人能肯定。在美国国家航空航天局(NASA)的“朱诺号”(Juno)最近一次环绕木星时,这艘机器人宇宙飞船拍摄到了了一个通常被称为“深渊”(Abyss)的黑云特征。周围的云图显示深渊位于漩涡的中心。由于木星大气层较暗的特征往往比较亮的特征更深入,深渊可能真的是它所出现的深洞——但这并没有更多的证据,这仍然仅是猜测。这个深渊被错综复杂的云团和其他漩涡风暴系统所包围,其中一些顶部是浅色的高空云团。这张照片是上个月拍摄的,当时“朱诺”号仅在木星云层上方15,000公里处经过。“朱诺”号下一次近距离掠过木星将是在7月。 Jupiter Abyss Image Credit: NASA, Juno, SwRI, MSSS; Processing & License: Gerald Eichstädt & Sean Doran Explanation: What’s that black spot on Jupiter? No one is sure. During the latest pass of NASA’s Juno around Jupiter, the robotic spacecraft imaged an usually dark cloud feature informally dubbed the Abyss. Surrounding cloud patterns show the Abyss to be at the center of a vortex. Since dark features on Jupiter’s atmosphere tend to run deeper than light features, the Abyss may really be the deep hole that it appears — but without more evidence that remains conjecture. The Abyss is surrounded by a complex of meandering clouds and other swirling…
