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 prominence s 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.
