[supernova1965 (Warren)]

I am game to show my ignorance but I was looking at the moon at night and then in the day and I noticed that it is different from night to day I must have seen it before but not taken much notice at night it is like it is in the first picture and in the day it was like it is in the second picture. I know this is probably something I should be able to reason out but it just has me stumped
