What are moon phases?
NASA explains that the moon goes through phases as it completes its 29.5-day orbit around Earth. The changing angles between the Sun, Moon, and Earth cause the different phases we observe. From Earth, the moon can look full, partially lit, or even disappear entirely, but we always see the same side. What changes is the amount of sunlight reflected from its surface, depending on its position in orbit.
The eight main moon phases are as follows:
New Moon - The moon is between Earth and the sun, so the side we see is dark (in other words, it's invisible to the eye).
Waxing Crescent - A small sliver of light appears on the right side (Northern Hemisphere).
First Quarter - Half of the moon is lit on the right side. It looks like a half-moon.
Waxing Gibbous - More than half is lit up, but it’s not quite full yet.
Full Moon - The whole face of the moon is illuminated and fully visible.
Waning Gibbous - The moon starts losing light on the right side.
Last Quarter (or Third Quarter) - Another half-moon, but now the left side is lit.
Waning Crescent - A thin sliver of light remains on the left side before going dark again.
