>The satellite is 1 million miles away from Earth at the L1 Lagrange point. What is it about optics that allows us to compare a photo of the stars taken at such a distance with one taken from the surface of the earth?
The fact that the earth in the picture is lit by the sun and has similar luminocity levels to looking at the sky from the surface during the day.
The background of the picture (the stars) on the other hand, have the same meagre light they always have.
