2021年12月29日 Giant Storms and High Clouds on Jupiter Image Credit: NASA/JPL-Caltech/SwRI/MSSS; Processing & License: Kevin M. Gill Explanation: What and where are these large ovals? They are rotating storm clouds on Jupiter imaged last month by NASA’s Juno spacecraft. In general, higher clouds are lighter in color, and the lightest clouds visible a...
这张JunoCAMM照片显示了木星的两个大型旋转风暴，是在朱诺号于2021年11月29日第38次经过木星时拍摄的。 影像来源：NASA/JPL-Caltech/SwRI/MSSS 图像处理：KEVIN M. GILL CC by 朱诺号在木星任务的木卫三飞掠期间收集的音轨提供了一个戏剧性的旅程。这是任务科学家在美国地球物理联盟秋季会议简报会上分享的亮点之一。 今天在新奥尔良举行的美国地球物理学会秋季会议上，在关于NASA朱诺号木星任务的简报中讨论了来自木卫二飞越的声音、磁场以及木星和地球海洋和大气之间的显著比较。 今天，在新奥尔良举行的美国地球物理联盟秋季会议上，关于NASA朱诺号木星任务的简报会上，讨论了木卫三飞行的声音、磁场以及木星与地球海洋和大气层之间的显著对比。 位于圣安东尼奥的西南研究所的朱诺号首席研...
During its 36th low pass over Jupiter, NASA’s Juno spacecraft captured this view of striking cloud bands and swirls in the giant planet’s mid-southern latitudes. The dark, circular vortex near the center of the image is a cyclone that spans roughly 250 miles (about 400 kilometers). The color at its center is likely to be the result of descending winds that c...
木星的带状外观是由云层形成的“天气层”造成的。这张合成图像分别显示了双子座北方望远镜和美国宇航局哈勃太空望远镜拍摄的木星红外和可见光（从左到右）视图。 影像来源：International Gemini Observatory/NOIRLab/NSF/AURA/NASA/ESA, M.H. Wong and I. de Pater (UC Berkeley) et al. 美国国家航空航天局（NASA）环绕木星运行的朱诺号探测器的新发现，为这颗行星独特而多彩的大气特征提供了一个更全面的画面，为了解其云层下不为人知的过程提供了线索。这些结果突出了木星周围的云带和云带的内部工作，以及它的极地气旋，甚至是大红斑。 研究人员今天在《科学》和《地球物理研究杂志：行星》上发表了几篇关于朱诺号大气发现的论文。其他论文发表在最...
2021年10月11日 Juno Flyby of Ganymede and Jupiter Video Credit: Images: NASA, JPL-Caltech, SWRI, MSSS; Animation: Koji Kuramura, Gerald Eichstädt, Mike Stetson; Music: Vangelis Explanation: What would it be like to fly over the largest moon in the Solar System? In June, the robotic Juno spacecraft flew past Jupiter’s huge moon Ganymede and took images tha...
On July 4, 2016, our Juno spacecraft arrived at Jupiter on a mission to peer through the gas giant planet’s dense clouds and answer questions about the origins of our solar system. Since its arrival, Juno has provided scientists with a treasure trove of data about the planet’s origins, interior structures, atmosphere and magnetosphere. Juno is the first miss...
2021年06月14日 Ganymede from Juno Image Credit: NASA/JPL-Caltech/SwRI/MSSS; Processing & License: Kevin M. Gill; Explanation: What does the largest moon in the Solar System look like? Jupiter’s moon Ganymede, larger than even Mercury and Pluto, has an icy surface speckled with bright young craters overlying a mixture of older, darker, more cratered t...
2021年06月08日 A Face in the Clouds of Jupiter from Juno Image Credit: NASA/JPL-Caltech/SwRI/MSSS/Jason Major Explanation: What do you see in the clouds of Jupiter? On the largest scale, circling the planet, Jupiter has alternating light zones and reddish-brown belts. Rising zone gas, mostly hydrogen and helium, usually swirls around regions of high pressure. C...
2021年03月24日 Aurorae and Lightning on Jupiter Image Credit: NASA, JPL-Caltech, SwRI; Text: Natalia Lewandowska Explanation: Why does so much of Jupiter’s lightning occur near its poles? Similar to Earth, Jupiter experiences both aurorae and lightning. Different from Earth, though, Jupiter’s lightning usually occurs near its poles — while muc...
2020年11月23日 A Jupiter Vista from Juno Image Credit: NASA/JPL-Caltech/SwRI/MSSS; Processing & License: Kevin M. Gill; Explanation: Why do colorful cloud bands encircle Jupiter? Jupiter’s top atmospheric layer is divided into light zones and dark belts that go all the way around the giant planet. It is high horizontal winds — in excess of 300 ...
