Astronomy lovers will pay attention to the sky this Saturday.

night of April 30 There will be a “black moon”.

This phenomenon occurs relatively infrequently, less than once a year.

But what is a black moon? How does it manifest? and can we see

To begin with, let’s make one thing clear: black moon is not an officially recognized term by astronomers.

The Moon goes through a cycle of phases, the main ones being the new moon, first quarter, full moon and last quarter.

Usually our satellite The cycle takes 29 days to complete.

A new moon occurs when the part of the Moon facing the Earth is not illuminated by the sun.

Then the star seems to have completely disappeared from our view.

This obviously happens every 29 days. But every year and every few months, two new moons are observed in the same calendar month, and the latter is known as the black moon or the dark moon.

Since the moon has completely lost its light, it will be impossible to see Saturday.

So why do we say astronomers will be watching the sky that night?

Black moons provide an excellent opportunity for space watchers, as the sky is darker due to the absence of light.

This makes it easier to see stars, constellations and objects in deep space such as star clusters and galaxies.

There are also some superstitions associated with the black moon.

Some believe it heralds a special moment when wishes come true and spells take effect.

For others, it means the end of the world is coming. Fortunately, they have been wrong in their predictions so far.
