Moon phase today: What the Moon will look like on January 31
Tomorrow is the Full Moon, which will mark the 14th day of the lunar cycle. After this point, it will start getting smaller each night as we progress towards the New Moon.
What is today’s Moon phase?
As of Saturday, Jan. 31, the Moon phase is Waxing Gibbous. According to NASA's Daily Moon Guide, 97% of the Moon will be lit up tonight.
If you don't have any visual aids, you can still enjoy glimpses of the Mares Fecunditatis and Crisium, and the Aristarchus Plateau. With binoculars, you'll also be able to see the Alphonsus Crater, Posidonus Crater, and Clavius Crater. With a telescope, you should also be able to spot the Apollo 12 landing spot, the Linne Crater, and the Caucasus Mountains.

What are Moon phases?
According to NASA, the lunar cycle lasts around 29.5 days. This is how long the Moon takes to travel once around Earth. Over that period, it passes through eight recognised phases. The same side of the Moon always faces our planet, however the portion that appears lit changes as the Moon moves along its orbit. The amount of sunlight reaching the Moon is what makes it appear full, partially illuminated, or almost invisible at different points in the cycle. The eight lunar 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.
