这张图片是3幅新近处理过的木卫二图像的其中之一，在卫星冰冷的表面上，你能看到各种地质特征的细节。这张图片显示的区域被称为“混沌过渡”，上面有着已经移动过的物质块以及表面隆起，这可能与木星引力所引发的壳层破裂有关。 图片来源：NASA/喷气推进实验室-加州理工/地外文明探索研究所（Search for Extraterrestrial Intelligence Institute，SETI Institute） 木卫二（Europa）欧罗巴的表面上，满是各式各样的地质景观，包括隆起的脊、带状的路、圆形的小凸顶，以及被地质学家称为“混沌地形”（chaos terrain）的破碎形貌。1990年代后期美国航空航天局（NASA）伽利略号木星探测器（Galileo）所拍摄的3幅图像，近期进行了再次处理，揭示了木卫二表面上...
2020 March 20 Morning, Planets, Moon and Montreal Image Credit & Copyright: Arnaud Mariat Explanation: Dawn’s early light came to Montreal, northern planet Earth, on March 18, the day before the vernal equinox. At the end of that nearly equal night the Moon stands above a dense constellation of urban lights in this serene city and skyscape. Of cou...
2020 March 9 Milky Way and Zodiacal Light over Chile Image Credit & Copyright: Roman Ponča (ht: Masaryk U.) Explanation: What is the band of light connecting the ground to the Milky Way? Zodiacal light — a stream of dust that orbits the Sun in the inner Solar System. It is most easily seen just before sunrise, where it has been called a false dawn,...
See Jupiter’s Great Red Spot as you’ve never seen it before in this work of art. Artist Mik Petter created this unique, digital artwork using data from the JunoCam imager on NASA’s Juno spacecraft. The art form, known as fractals, uses mathematical formulas to create art with an infinite variety of form, detail, color and light. The tumultuous atmospheric zo...
2017年9月1日，美国国家航空航天局（NASA）的朱诺号（Juno）木星探测器上的JunoCam成像仪捕捉到了这幅木星南部赤道地区的图片。由于该图像是定向拍摄的，因此木星的两级（不可见）从左至右分布在框架内。 版权：NASA/喷气推进实验室-加州理工学院（JPL-Caltech）/美国西南研究院（Southwest Research Institute, SwRI）/马林空间科学系统公司（Malin Space Science Systems, MSSS）/凯文•M•吉尔（Kevin M. Gill） NASA的朱诺号任务提供了其关于木星大气中水含量的首次测量结果。根据近期发表于《自然天文学》（Nature Astronomy）期刊上的朱诺号探测器的测量结果估计，在木星的赤道地区，水分子占大气中分子的0.25...
2020 February 25 Jupiter’s Magnetic Field from Juno Video Credit: NASA, JPL-Caltech, Harvard U., K. Moore et al. Explanation: How similar is Jupiter’s magnetic field to Earth’s? NASA’s robotic Juno spacecraft has found that Jupiter’s magnetic field is surprisingly complex, so that the Jovian world does not have single magnetic p...

Thick white clouds are present in this JunoCam image of Jupiter’s equatorial zone. These clouds complicate the interpretation of infrared measurements of water. At microwave frequencies, the same clouds are transparent, allowing Juno’s Microwave Radiometer to measure water deep into Jupiter’s atmosphere. The image was acquired during Juno&#...
A multitude of swirling clouds in Jupiter’s dynamic North North Temperate Belt is captured in this image from NASA’s Juno spacecraft. Appearing in the scene are several bright-white “pop-up” clouds as well as an anticyclonic storm, known as a white oval. This color-enhanced image was taken at 4:58 p.m. EDT on Oct. 29, 2018, as the spacecraft perf...
