它可能看起来像一个纸月亮。航行经过一个帆布太阳。但这些不是硬纸板云。这不是虚构的。这张橙色天空的特色图片是真实的——这是本月早些时候发生的两次日食的数字合成照片。第一张照片是用普通望远镜拍摄的，它捕捉到了过度曝光的太阳和曝光不足的月球，而第二张照片是用太阳望远镜拍摄的，它捕捉到了背景太阳色球层的细节。太阳像画布一样的质地是通过对氢发出的一种非常特殊的红色阴影进行成像而发现的。在太阳的边缘可以看到几个日珥。这张照片是在中国内蒙古锡林郭勒日落前拍摄的。月球是由致密的岩石构成的，太阳是由炽热的气体构成的，云是由漂浮的水滴和冰构成的，这也不是虚构的。

It may look like a paper Moon. Sailing past a canvas Sun. But those are not cardboard clouds. And it's not make believe. The featured picture of an orange colored sky is real -- a digital composite of two exposures of the solar eclipse that occurred earlier this month. The first exposure was taken with a regular telescope that captured an overexposed Sun and an underexposed Moon, while the second image was taken with a solar telescope that captured details of the chromosphere of the background Sun. The Sun's canvas-like texture was brought up by imaging in a very specific shade of red emitted by hydrogen. Several prominences can be seen around the Sun's edge. The image was captured just before sunset from Xilingol, Inner Mongolia, China. It's also not make-believe to imagine that the Moon is made of dense rock, the Sun is made of hot gas, and clouds are made of floating droplets of water and ice.
