What is today’s moon phase?

As of Wednesday, Jan. 7, the moon phase is Waning Gibbous. According to NASA’s Daily Moon Guide, 80% of the moon will be lit up tonight.

There’s lots to see tonight when you look up. Without any visual aids, you’ll be able to spot the Mares Imbrium and Tranquillitatis as well as the Kepler Crater. With binoculars, you’ll also see the Gassendi and Alphonsus Craters, and the Mare Nectaris. Add a telescope to your lineup if you want to spot even more, including the Apollo 15 landing spot, the Schiller Crater, and the Descartes Highlands.

What are moon phases?

According to NASA, the Moon completes one full orbit of its phases in around 29.5 days, a period referred to as the lunar cycle. As the Moon travels around the Earth, it passes through a sequence of distinct phases. Although the same side of the Moon always faces Earth, the portion lit by the Sun changes depending on its position in orbit. This variation in sunlight is what causes the Moon to appear fully illuminated, partly lit, or completely dark at different points in the cycle. The lunar cycle is made up of eight phases:

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.
