朱诺号影像:木卫一的影子

2019 October 7 Io Eclipse Shadow on Jupiter from Juno Image Credit & License: NASA/JPL-Caltech/SwRI/MSSS; Processing: Kevin M. Gill Explanation: What’s that dark spot on Jupiter? It’s the shadow of Jupiter’s most volcanic moon Io. Since Jupiter shines predominantly by reflected sunlight, anything that blocks that light leaves a shadow....

木星与卫星

2019 October 5 Jupiter and the Moons Image Credit & Copyright: Derek Demeter (Emil Buehler Planetarium) Explanation: After sunset on October 3, some of the Solar System’s largest moons stood low along the western horizon with the largest planet. Just after nightfall, a pairing of the Moon approaching first quarter phase and Jupiter was captured in ...

NASA’s robotic spacecraft Juno is continuing on its 53-day, highly-elongated orbits around our Solar System’s largest planet. The featured video is from...

哈勃太空望远镜拍到了木星的大红斑

This new Hubble Space Telescope view of Jupiter, taken on June 27, 2019, reveals the giant planet’s trademark Great Red Spot, and a more intense color palette in the clouds swirling in Jupiter’s turbulent atmosphere than seen in previous years. The colors, and their changes, provide important clues to ongoing processes in Jupiter’s atmosphe...

虎口里的木星和银河

2019 August 7 Jupiter Engulfed and the Milky Way Image Credit & Copyright: Mohammad S. Hayati Explanation: This is a good month to see Jupiter. To find our Solar System’s largest planet in your sky, look toward the southeast just after sunset — Jupiter should be the brightest object in that part of the sky. If you have a binoculars or a small...

木星上的深渊

NASA’s Juno spacecraft captured this view of an area within a Jovian jet stream showing a vortex that has an intensely dark center. Nearby, other features display bright, high altitude clouds that have puffed up into the sunlight. The color-enhanced image was taken at 12:55 a.m. PDT (3:55 a.m. EDT) on May 29, 2019, as the spacecraft performed its 20th scienc...

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 stunni...

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。...

在海滩远眺火星

2019 June 8 在海滩远眺火星 影像提供与版权: Jack Fusco 说明: 在去年北半球夏季末的大冲之后,火星仍然在夜空大放光芒。因此,这颗天体轻易的吸引这二位观星者的注目,并让他们伫足入镜这幅摄于地球.大索尔的天与地景观。此外,在这张长曝光影像里,银河垂贯过视野,中心鼓核悬在西南地平线附近,而生物发光造成的淡蓝晕光(俗称蓝眼泪),在菲佛海滩附近的海浪中漂荡。目前已昏暗很多的火星,日落后会出现在西方的地平线附近。不过在这个月,木星最靠近我们也最为明亮,并将在6月10日运行到冲的位置。届时观星者可在南方地平线的银河中心繁星附近,找明亮的木星。 On the Beach with Mars Image Credit & Copyright: Jack Fusco Explanation: At ...

木星和烟斗星云

2019 June 6 木星和烟斗星云 图片来源及版权:Alain Maury, Jean-Marc Mari 说明:现在,在星系丰富的星场和星云的映衬下,明亮的木星在夜空中闪耀。在这张中央银河系的彩色长焦照片中,木星压倒性的光芒在画面顶部闪耀。该场景横跨天空约20度,LDN 1773黑色的轮廓背对着星场,它们的组合勾勒出一个烟斗的颈和管形状,因此这片黑暗的星云也常被称为烟斗星云。烟斗星云是蛇夫座星云的一部分。蛇夫座星云位于450光年外,致密的气体和尘埃核心正在坍缩形成恒星。6月12日,木星在天空中的正对着太阳,距离地球只有36光分。天文爱好者或许能在天空中木星强光左下方的深色斑纹里看到蛇状星云。 The Planet and the Pipe Image Credit & Copyright: Ala...
