太阳射线爆发如火蛇涌动

epa04837534 A NASA handout made available on 08 July 2015 shows flaring, active regions of the sun highlighted in this new image combining observations from several telescopes. High-energy X-rays from NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) are shown in blue; low-energy X-rays from Japan's Hinode spacecraft are green; and extreme ultraviolet light from NASA's Solar Dynamics Observatory (SDO) is yellow and red. All three telescopes captured their solar images around the same time on 29 April 2015. The NuSTAR image is a mosaic made from combining smaller images.

科学家用几台天文望远镜在同一时间拍摄太阳表面后合成图像。太阳活动剧烈的地方突出显示出来,看起来更加明亮。太阳无时无刻都在发生剧烈活动,进而产生太阳黑子、耀斑和日冕物质喷发等现象。图片由美国太空总署(NASA)于星期四发布。(欧新社)
