Astronauts in space don't see stars for another reason beyond the unending glare
of the sun: their windows and spacesuit visors are all heavily leaded, both to
control glare (since the sun is 1.4 times brighter in space at one astronomical
unit than on the surface of earth), and to help protect against radiation. Try
this: at night: put on some welders goggles. How many stars do you see???
