这张照片捕捉到了一个意想不到的剪影。是哪一个？它不是太阳黑子，太阳黑子是由太阳明亮的圆盘周围可见的集中磁场造成的小的黑暗区域。太阳黑子通常会持续数周，因为这些黑子以前就见过。它不是国际空间站（ISS），也就是图片左中那个黑色的小建筑。这是因为这张特色图片是用亚秒计时来记录这个标志性的结构在太阳之前经过的。是飞机。就在6月份，在捷克共和国的普拉塞克，一架飞机开始了自己的微型日偏食。结果就是太阳的三重排列图像。这位摄影师估计，从那个位置随机拍摄到同时包含空间站和飞机轮廓的太阳图像的概率大约是3000万比一。APOD的主要NASA网站正在迁移：从APOD .

This shot captured an unexpected silhouette. Which is it? It isn't the sunspots, the small dark regions caused by concentrated magnetic fields visible around the Sun's bright disk. Sunspots typically last for weeks and were expected, since these spots were seen previously. It isn’t the International Space Station (ISS), the small dark structure on the middle left. This is because the featured picture was planned with sub-second timing to record the iconic structure passing before the Sun. It is the airplane. Just as this exposure was taking place in June, from Prasek in the Czech Republic, an airplane began its own miniature partial eclipse. The result is this triply aligned image of our Sun. The photographer estimates that the chance of any random Sun image containing silhouettes of both a space station and an airplane, from that location, is about 30 million to one.
