A waxing moon — sometimes addressed as a “young moon” — is ever encountered in the west after sundown. At this moon stage, the Earth, moon and sun are settled almost align in space. If they were more accurately on ordinate, as they're at new phase of the moon, we would not see the moon. The moon would change its location over the sky on the daytime, hidden in the sun’s blaze. Alternatively, a waxing crescent moon is seen from a day to some days more after new moon. It arises 60 minutes to several hours at the back of the sun and keeps up to the sun over the sky during daytime. When the sun adjusts, and the sky dims, the moon comes up into view in the western sky.
As the waxing crescent moon is closely on align with the Earth and sun, the “day side” is facing up mostly aside from us. We catch only a slim fraction of the day side: a crescent-shaped moon. Each evening, as the moon is displacing eastbound in scope roughly the Earth, the moon seems further from the sunset blaze. Each evening, as the moon’s orbital rotation holds it aside from the Earth/sun line, we discover more of the moon’s day side. So the half-moon in the west afterward sunset seems to mount, or get fatter every single evening.
See that a crescent-shaped moon has none in common with Earth’s vestige on the moon. The only time Earth’s darkness can fall on the moon comes when it's full moon, during an eclipse of the moon. There's a shade on a crescent moon, but it’s the moon’s possessed shadow. Nighttime on the moon goes on the part of the moon overwhelmed in the moon’s own shadow. In a similar way, night on Earth goes on the part of Earth overwhelmed in Earth’s own shadow.
You sometimes can discover a wan gleam on the dimmed part (nighttime side) of a crescent-shaped moon. This gleam is because of the light mirrored from Earth’s daytime side. It’s addressed as “earthshine.”
