Recap Lunar phases Half of the Moon is always lit by the sun but phases occur because that lit half isn’t entirely visible from the Earth (eclipses are an exception) It takes 29.5 days for the Moon to go through all of its phases If the Moon comes exactly between the Earth and the Moon and the Moon’s shadow falls on the Earth’s surface, that part of the Earth experiences a Total Solar Eclipse If you’re just outside the shadow region you’ll see a Partial Solar Eclipse If the Moon’s shadow doesn’t quite reach the Earth, that region sees an Annular Solar Eclipse If the Earth comes exactly between the Sun and the Moon it causes a Total Lunar Eclipse Partial Lunar Eclipses and Penumbral Lunar Eclipses also occur New Notes Why can you still see the Moon during a Total Lunar Eclipse? Light from the Sun is bent around the Earth’s atmosphere. The atmosphere absorbs the blue color, leaving only red light to travel around into the Earth’s umbra and fall on the Moon. BTW, the light-bending effect is why the Sun looks really red at sunset
