我们的万圣节太阳

Active regions on the sun combined to look something like a jack-o-lantern’s face on Oct. 8, 2014. The active regions appear brighter because those are areas that emit more light and energy — markers of an intense and complex set of magnetic fields hovering in the sun’s atmosphere, the corona. This image blends together two sets of wavelengths at 171 and 193 angstroms, typically colorized in gold and yellow, to create a particularly Halloween-like appearance.

2014年10月8日，太阳上的活跃区域组合在一起看起来像一个南瓜灯的脸。活动区域显得更亮，因为它们是发出更多光和能量的区域-强烈而复杂的一组磁场的标志盘旋在太阳的大气层—日冕中。这张照片将两组波长分别为171埃和193埃的光线混合在一起，颜色通常为金色和黄色，营造出一种特别万圣节的氛围。
