Explanation: How complex is Jupiter? NASA’s Juno mission to Jupiter is finding the Jovian giant to be more complicated than expected. Jupiter’s magnetic field has been discovered to be much different from our Earth’s simple dipole field, showing several poles embedded in a complicated network more convoluted in the north than the south. Further, Juno’s radio measurements show that Jupiter’s atmosphere shows structure well below the upper cloud deck — even hundreds of kilometers deep. Jupiter‘s newfound complexity is evident also in southern clouds, as shown in the texture and color enhanced featured image taken last month. There, planet-circling zones and belts that dominate near the equator decay into a complex miasma of continent-sized storm swirls. Juno continues in its looping elliptical orbit, swooping near the huge planet every month and exploring a slightly different sector each time around.

说明: 木星究竟有多复杂？NASA的朱诺号任务发现这颗巨行星木星比预期中更加复杂。结果发现木星的磁场与地球的简单偶极磁场截然不同，它呈现出多个磁极，并嵌入在一个复杂的网路中，北半球的磁场比南半球更加错综复杂。此外，朱诺号的电波测量显示，木星的大气层在上层云层之下的结构甚至延伸到数百公里深。木星新发现的复杂性在南半球的云层中也显而易见，正如上个月拍摄的纹理和色彩增强的特色图像所示。在那里，赤道附近占主导地位的行星环绕区域和带状结构逐渐衰退成由大陆大小的风暴漩涡构成的复杂雾气。朱诺号继续在其环绕木星的椭圆轨道上运行，每个月都会掠过这颗巨大的行星，每次都会探索略有不同的区域。
