The entire Orion Nebula spans about 40 light years and is located in the same spiral arm of our Galaxy as the Sun.

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...
