      Great question James! The answer is that when the sun comes up it scatters light across the sky and the blue light in the spectrum of light waves from the sun is brighter than the faint light reaching us from the distant stars, As a result we cannot see starlight when the sun is shining.

      The stars are still there during the day time, you just can’t see them because the light from the sun is much brighter and hides the stars. Think of it like your mum shouting up the stairs at you but you can’t hear it because you’ve got your music on, it’s similar to that. Your mum is still shouting at you, you just can’t hear it.

      They are always there. It’s just that their brightness is low in comparison to that of the sun, so that they may not readily be discernible on a bright day.
