According to NASA, the lunar cycle lasts 29.5 days in total. Last weekend, we reached the start of a new cycle, marked with the new moon (and a partial lunar eclipse). The lunar cycle is the moon process moving through its eight unique visibility phases. These different phases occur when the sun illuminates different parts of the moon while it orbits around the earth.
After nights of nothing to see, there is finally enough moon in the sky to remove the binoculars. Let’s take a look at what’s going on this evening on September 25.
What is the moon phase today?
From Thursday, September 25, the moon phase is a croissant to wax, and according to the daily observation of NASA, there are 13% visible.
After the nights of nothing, we finally have something to admire tonight, so take a look. With just your naked eye, look at the top right of the moon to see the criesium of mare. More to the middle, you will see the fecunditatis mare. If you are in the southern hemisphere, they will be positioned downwards.
If you have twins, you will also have an overview of the Endymion crater. Top Tip of NASA: If you have a telescope, you could simply spot three smaller craters aligned in its border.
When is the next full moon?
The next full moon will take place on October 6. The last full moon took place on September 7.
What are the phases of the moon?
NASA tells us that the phases of the moon are part of a 29.5 day cycle of the Moon orbit. This changes the corners between the sun, the moon and the earth. The phases of the moon are the appearance of the moon of the earth as it goes out; Sometimes it looks full, sometimes it seems that it has disappeared entirely, but we always see the same side of the moon, it is how much it is lit by the sun that changes according to where it is in its orbit.
Mashable lighting speed
This is how we get complete moons, half moons and moons that seem completely invisible. There are eight main moon phases, and they follow a repetitive cycle:
New moon – The moon is between the earth and the sun, so the side we see is dark (in other words, it is invisible to the eye).
Croissant – A small ribbon of light appears on the right side (northern hemisphere).
First trimester – Half of the moon is lit on the right side. It looks like half a moon.
Wax gibbous – More than half is lit, but it is not yet full.
Full moon – The whole face of the moon is illuminated and fully visible.
Declining Gibbous – The moon begins to lose light on the right side.
Last quarter (or third trimester) – Another half -moon, but now the left side is on.
Decreasing crescent – A thin ribbon of light remains on the left side before returning dark.
