is the shadow on a crescent moon the earth, or is it the dark side of the moon. i was taught in science a while ago that its the dark side of the moon, and an eclipse of the earth on the moon is something different and more rare. but what i dont get is, if we are seeing mostly the dark side of the moon, wouldnt that mean its in front of us, ie, closer to the sun? then how could we see it at night? i drew a simple picture to show what i mean. the lines from the earth to the moon represent what we would be able to see. so what am i missing?
