Although we usually see only the brightly lit part of the moon during its crescent phase, we sometimes see the other part too, though dimly lit.
What’s the reason?
Earth reflects the sun’s light falling on it just like the moon does. The earth, in fact, is a better reflector than the moon. The oceans which cover three-fourths of the earth’s surface, reflect a lot of solar radiation back into space. So just as we have moonlight here, there is earthlight on the dark side of the moon. It is this earthlight which makes the moon beyond the crescent dimly visible to us.
