Moon phase today: What the Moon will look like on January 18
It’s officially the New Moon, which means the Moon is positioned between the Earth and the Sun and isn’t visible in the sky. It's also the final day of a the current lunar cycle, so from now on, the Moon will appear brighter and brighter each night until the Full Moon.
What is today’s Moon phase?
As of Sunday, Jan. 18, the Moon phase is New Moon. According to NASA's Daily Moon Guide, 0% of the Moon will be lit up tonight.
Unsurprisingly, with 0% visibility, there's 0% chance of spotting anything on the Moon tonight. Things will start to get brighter over the coming days as we work through the new lunar cycle.

What are Moon phases?
Moon phases make up the lunar cycle, which NASA says lasts about 29.5 days, the time it takes the Moon to complete one full orbit around Earth. As the Moon travels around our planet, it passes through eight distinct phases. While the same side of the Moon always faces Earth, the amount of sunlight illuminating it changes depending on its position in orbit. This is why the Moon can appear full, partially lit, or completely dark at different points in the cycle. The eight phases of the lunar cycle 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.
