Fascinating images from all parts of science!
Although my job is writing about science — putting it into words — there are times when images can say so much more than words. I am not much of a photographer or graphic artist, so most of these images were provided by other people, who are credited in the captions when I can remember who they were.
Two Sides of the Moon
