It's now the First Quarter, which means the Moon is half full, and there's plenty surface area illuminated to spot features.
What is today’s Moon phase?
As of Sunday, June 21, the Moon phase is First Quarter. Tonight, 54% of the moon will be be lit up, according to NASA's Daily Moon Guide.
With just your naked eye, tonight you'll be able to see the Mares Fecunditatis, Serenitatis and Crisium. With binoculars, you'll also catch a glimpse of the Endymion Crater, Posidonius Crater, and the Mare Nectaris. If you have a telescope, this will help you see all this plus the Linne Crater, the Descartes Highlands, and the Rupes Altai.
When is the next Full Moon?
The next Full Moon will take place on June 29.
What are Moon phases?
According to NASA, the Moon completes one orbit around Earth in about 29.5 days, moving through eight recognised phases along the way. While the same side of the Moon always faces our planet, the amount of its surface lit by the Sun changes as it travels around Earth. As a result, we see the Moon appear in different shapes over the course of a month, from slender crescents and half moons to a bright Full Moon. This repeating sequence of phases is known as the lunar cycle.
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).
Mashable Light Speed
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.
