From our viewpoint, the Moon varies each night, moving through its lunar cycle as different sections of its illuminated side come into view. So, what does that imply for the Moon tonight? Keep reading to learn more.

What is the moon phase today?

As of Wednesday, Jan. 7, the current moon phase is Waning Gibbous. Per NASA’s Daily Moon Guide, 80% of the moon will be lit up this evening.

There’s a lot to witness tonight when you gaze upward. Without any optical tools, you’ll be able to see the Mare Imbrium and Mare Tranquillitatis along with the Kepler Crater. With binoculars, you’ll also catch sight of the Gassendi and Alphonsus Craters, and the Mare Nectaris. Use a telescope if you wish to view even more, such as the Apollo 15 landing area, the Schiller Crater, and the Descartes Highlands.

When is the upcoming full moon?

The next full moon will take place on Feb. 1. The last full moon occurred on Jan. 3.

What are the phases of the moon?

According to NASA, the Moon completes its full orbit of phases in approximately 29.5 days, referred to as the lunar cycle. As the Moon moves around Earth, it experiences a succession of distinct phases. While the same side of the Moon perpetually faces Earth, the part illuminated by the Sun shifts according to its orbital position. This variation in sunlight results in the Moon appearing fully lit, partially illuminated, or entirely dark at various points in the cycle. The lunar cycle includes eight phases:

New Moon – The Moon is situated between Earth and the Sun, making the side we see dark (it’s not visible).

Waxing Crescent – A slight sliver of light emerges on the right side (Northern Hemisphere).

First Quarter – Half of the Moon is illuminated on the right side. It resembles a half-moon.

Waxing Gibbous – More than half is illuminated, but it hasn’t reached full yet.

Full Moon – The entire face of the Moon is lit up and entirely visible.

Waning Gibbous – The Moon begins to lose light on the right side. (Northern Hemisphere)

Third Quarter (or Last Quarter) – Another half-moon, but this time the left side is lit.

Waning Crescent – A slender sliver of light persists on the left side before going dark again.
