The moon is looking brighter every night, and we’re inching closer to the next full moon. But let’s take a look at where we are in the lunar cycle first.
The lunar cycle is a series of eight unique phases of the moon’s visibility. The whole cycle takes about 29.5 days, according to NASA, and these different phases happen as the Sun lights up different parts of the moon whilst it orbits Earth.
What is today’s moon phase?
As of Sunday, Aug. 3, the moon phase is Waxing Gibbous. According to NASA’s Daily Moon Observation, the moon will be 69% lit up tonight.
It’s day 10 of the lunar cycle, and there’s a lot to see when we look up tonight. With just your naked eye (no visual aids required), you’ll be able to spot the Copernicus Crater, the Mare Fecunditatis, and the Mare Crisium.
With binoculars, enjoy a glimpse of the Aphonsus Crater, Posidonius Crater, and the Mare Frigoris. With a telescope, you can also see the Rima Arladaeus, the Descartes Highlands, and Fra Mauro Highlands, a hilly region of the moon where the Apollo 14 landed.
When is the next full moon?
The next full moon will be on August 9. The last full moon was on July 10.
What are moon phases?
According to NASA, moon phases are caused by the 29.5-day cycle of the moon’s orbit, which changes the angles between the Sun, Moon, and Earth. Moon phases are how the moon looks from Earth as it goes around us. We always see the same side of the moon, but how much of it is lit up by the Sun changes depending on where it is in its orbit. This is how we get full moons, half moons, and moons that appear completely invisible. There are eight main moon phases, and they follow a repeating cycle:
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.
Last Quarter (or Third 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.
