It’s the start of a new lunar cycle, which can only mean one thing: the Moon is working towards being full again. Over the next few nights, we’ll notice it getting bigger in the sky.
What is today’s Moon phase?
As of Saturday, Sept. 12, NASA’s Daily Moon Guide tracker tells us the Moon is in the Waxing Crescent phase, with 2% of its surface visible.
When is the next Full Moon?
The next Full Moon will take place on September 26.
What are Moon phases?
As the Moon orbits Earth, its appearance changes over the course of roughly 29.5 days, creating what we know as the lunar cycle, according to NASA. The phase we see depends on where the Moon is in relation to Earth and the Sun, and how much of its sunlit side is facing us. Throughout the cycle, it moves from a slender crescent to a half Moon and eventually a Full Moon, before the pattern begins again.
The eight phases are:
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. (Northern Hemisphere)
Third Quarter (or Last 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.
