木星湍流大气中的摩卡漩涡

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...

朱诺号:科学研究成果首次提供木星大气的三维视图

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...

庆祝在木星的5周年

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...

朱诺号影像:木星云层上的脸谱

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...

木星的极光及闪电

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...

朱诺号的木星景观

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 ...

“精灵”在木星的大气中嬉戏

This illustration shows the lightning phenomenon known as a sprite and what a sprite could look like in Jupiter’s atmosphere. Named after a mischievous, quick-witted character in English folklore, sprites last for only a few milliseconds. They feature a central blob of light with long tendrils of light extending down toward the ground and upward. In Ea...
