A Paper Moon Solar Eclipse

Explanation: 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.

说明: 乍看之下,影像似在呈现一轮纸月亮,滑过帆布太阳的前方。不过,影像里的朵不是纸板云,而场景也非虚构。这幅主题影像里的橙色天空是真的,内容则是摄于这个月稍早日食期间2张照片的数位叠合。在使用一般望远镜拍摄的第1张照片,里头有过曝的太阳和曝光不足的月亮。第2张来自太阳望远镜的照片,记录了背景太阳色球的细微结构。其中,太阳帆布般的纹理,则是在的特定红光波段取像的产物。此外,在太阳的临边可见到数个日珥。这幅日落时分影像,摄于中国内蒙古自治区的锡林郭勒盟。其他一些非虚构的事实,还包括:月球的成分是致密的岩石、太阳是一团炽热的气体、以及云是漂浮在空中的成团晶微粒。
