What is the black moon?

This is the astronomical event in which the Moon is so close to the Sun in our sky that we cannot see it from Earth , not even at sunset or sunrise. The force of the sun’s glow makes the moon invisible to our eyes.

The black moon or dark moon , as it is also known, can last between 1.5 and 3.5 days . The difference between the new moon and the black moon is not completely closed, since it can refer to the absence of a new moon in that month, the lack of a full moon or even a second new moon within the same calendar month. .

The first supermoon of 2015, which took place on February 18, for example, was a black moon that, being in a new phase, could not be observed in all its splendor. The satellite was 356,991 kilometers from Earth (its closest point). The next black moon took place in January 2018.

It is not an astronomical term

Like “Blood Moon” or “Blue Moon”, “Black Moon” is not an astronomical term either. In fact, if you ask astronomers, both professional and amateur, very few will have heard of it.

Regarding its definition, we can say that we are facing a “Black Moon” if:

– There is a new moon twice in the same month. It is similar to the Blue Moon, which has become a common term for the second full Moon in a month. This is the most commonly used definition of a black moon.
– There is no new moon in a month. This could only happen in February, and therefore it is somewhat rare, that is, it can happen once every 5 to 10 years.
– The term ‘black moon’ could also simply refer to each new Moon, since then we are seeing the dark or black side of the Moon.
– Sometimes it is also applied to refer to the third new moon when there are four in a season, which is actually one of the definitions of “blue moon” when the same thing happens to the full moon.

There is no astronomical meaning for Black Moon. Nothing spectacular happens, except the usual absence of the new moon in the sky, plus the strongest tides, called “primroses”, that we get for a few days around each full moon and new moon.

When is the next black moon?

If you are willing to use any of the above definitions, you will have a Dark Moon at least once a year and sometimes twice. However, if we follow the standard definition of “two new moons in a month”, black moons become a little stranger to see, and they occur, as we have discussed, approximately every 32 months (two to three years ).

In North America, the next Black Moon will occur on July 31, 2019, at 11:12 pm

In Europe or anywhere else east of the time zone, the next Black Moon will take place on August 30, 2019.


What will we see during a black moon?

During the new Moon phase, the Moon is not illuminated by the Sun and appears to disappear from the night sky. A new Moon is practically invisible to the naked eye, exposing spectacular conditions for observing the rest of the cosmos, be it galaxies, individual stars, or nebulae.

Remember: The “new moon” has its dark side in front of us. It does not reflect any light from the Sun because the Earth’s natural satellite is aligned between the Earth and the Sun.
