The angle of refraction
... When light travels from a vacuum of space into our atmosphere there is a very slight refraction. This is normally not noticed, except when there is a total eclipse of the moon. During the total eclipse stage, the moon is not visible, but will appear very slightly. This is because it has been lit up ...
