If you want to know how bright the night sky will be, how much will the moon have
According to NASA, the moon moves in a cycle of eight unique stages in about 29.5 days. These different stages occur when the sun illuminates various parts of the moon as it orbits the earth.
Whether you’re an avid astronomy fan or astrology fan, understanding the moon phases can add a little cosmic magic to your night.
That’s what the Moon does today (June 19, 2025).
What is the moon phase today?
As of Thursday, June 19, the monthly phase was the previous quarter. According to NASA, at this stage, the moon only looks about half light, 42% to be exact.
This is the 23rd day of the lunar cycle, and if you are in the northern hemisphere you will see the Copernicus Crater and the Oceanus procellarum, a large lunar mare called the “Ocean Storm” and the upper left is the upper left. If you are in the southern hemisphere, these will appear in the lower right corner of the moon. No binoculars or telescopes are needed, and these can be seen with the naked eye.
Copernicus is the most famous of the lunar craters, spreading 57 miles across the ground and 2.2 miles deep. According to NASA, this is perspective, about twice as many as the Grand Canyon.
Oceanus procellarum is not very small either. It covers over 10% of the moon and covers more than 1,600 miles.

When is the next full moon?
The full moon in June is on June 11th. The next full moon will be on July 10th.
What is the moon phase?
The moon phase is part of the 29.5-day lunar cycle. NASA Tell us that it is caused by the angle between the sun, the moon and the earth. The moon phase is what the moon looks like on the earth around us. We always see the same side of the moon, but how much does the Sun change light up depending on where it is in orbit. So sometimes it looks full, sometimes even half, sometimes it doesn’t exist at all. There are eight main moon phases that follow the repetitive cycle:
new moon – The moon is between the earth and the sun, so the side we see is dark (in other words, the eyes cannot see).
Waxing the crescent moon – A small piece of light appeared on the right (northern hemisphere).
First quarter – Half of the moon lit up on the right. It looks like half a month.
Waxed eldest son – More than half the lights are lit, but not very full yet.
Full Moon – The entire face of the moon is illuminated and fully visible.
Wake up eldest son – The moon begins to lose light on the right.
Last quarter (or Q3) – Another half month, but now the left side is lit.
A decayed new moon – A thin light left on the left and then turned black again.
