We’re moving towards to the New Moon, which means for the next few nights the moon is going to look smaller and smaller to us. This is normal as we work though the lunar cycle, and we’re currently on day 18.
What is today’s moon phase?
As of Saturday, Nov. 8, the moon phase is Waning Gibbous. This means 87% of the moon is lit up tonight, according to NASA’s Daily Moon Observation.
No visual aids? No problem, there’s still lots for you to see tonight, like the Copernicus Crater, the Mare Tranquillitatis, and the Tycho Crater. A pair of binoculars will let you see even more, including Gassendi Crater, Clavius Crater, and the Alphonsus Crater. If you’ve got a telescope handy, it’s worth using to check out Reiner Gamma, the Apollo 17 landing site, and the Fra Mauro Highlands.
When is the next full moon?
The next full moon will be on Dec. 4.
What are moon phases?
NASA notes that as the Moon orbits Earth over about 29.5 days, it goes through a series of phases. These phases occur because of the changing angles between the Sun, Moon, and Earth. Depending on its position, the Moon can appear fully illuminated, partly illuminated, or completely hidden, even though we always see the same side. What changes is how much sunlight reflects off its surface, creating a repeating sequence known as the lunar cycle.
The eight main moon phases are:
Mashable Light Speed
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.
