comment Why CAN we see the new moon at night?
@Igor, David: If you hold up a tennis ball in front of a desklamp, you can see the same phases by moving the tennis ball around your head. If you move it so you the shadow of the tennis ball fully occludes the tennis ball, you will find yourself facing the lamp. Applying the analogy, the only time a new moon (or anything between the last/first quarters) would be visible should be when our section of the Earth is facing the Sun, i.e. daytime. Yet, we still see crescent moons & new moons at night. Is this a little more clear?
