Enjoy these great photos of the July supermoon. It's the first of four supermoons in a row. August will have two supermoons and September will have one.
Occasionally you get the chance to look for a very young moon, less than 24 hours old. Those in North America, may see one just after sunset on April 20.
A new moon generally can't be seen, except during a solar eclipse. They cross the sky with the sun during the day. The moon's shadow side is toward Earth.
The full moon, opposite the sun in its orbit, shows us its sunlit side. The moon appears full a couple of days before and after the exact moment of full moon.
The first quarter moon is halfway between new and full moon. Half of the moon is illuminated and it's a quarter of the way through it's orbit around the Earth.
As the moon orbits Earth, we see varying fractions of its lighted face. These are the changing phases of the moon. Read four tips to understanding moon phases.
