Blood Moon: what is it and what time can you see it this weekend

Of all the natural phenomena carried out by the Moon, without a doubt, the so-called Blood Moon must be one of the most spectacular.

However, it is actually a more common astronomical phenomenon than we think, since it is a eclipse lunar. The phenomenon occurs when the Moon passes through the shadow of the Earth, and this, like all solar system objects, goes with his shadow attached. When the natural satellite passes through this, which is very large, the eclipse occurs, which lasts for hours.

All extended objects like our world produce various shadows. In this way, the Earth generates a tenuous shadow (umbra) y a deeper shadow (penumbra); where the two coincide, the object is darker, he explained the researcher from the UNAM Institute of Astronomy, Julieta Fierro Gossman.

When the Moon transits the umbraa part is overshadowed, but when doing so by the penumbra it appears almost totally dark, because the sunlight passes through the Earth’s atmosphere and is projected onto it. In fact, it does not completely disappear, but instead appears red.

These eclipses are not common because the plane of our planet’s orbit around the Sun is tilted relative to the plane of the Moon, and they form an angle of five degrees. However, there is always an eclipse season when the Moon and Earth are aligned with the Sun.

However, on this occasion, it is enough to look up at the sky between the night of this Sunday, May 15, and the early hours of Monday, May 16, to observe (at least from South and Central America, a large part of North America, south and west of Europe, south and west of Asia, Africa, in the Pacific, Atlantic, Indian oceans and from Antarctica) east eclipse lunar total.
