What is a Blood Moon? What does the appearance of a Blood Moon mean?

Blood moon phenomenon. A red moon usually occurs during a lunar eclipse. This is because the thick atmosphere absorbs all the violet, blue, green, and yellow light, leaving only red light to penetrate.

The same is true of the red moon during a total lunar eclipse, where the atmosphere refracts red light onto the surface of the moon, so we can still see the red moon hanging in the sky in the shadow of the earth.

There is one more explanation.

During a total lunar eclipse, if you observe it from the moon, you will see a total solar eclipse. It's just that a total solar eclipse on the Moon and a total solar eclipse on Earth are at least a few differences: 1) from Earth, the Moon and the Sun have almost the same viewing angle; From the Moon, the Earth's perspective is much larger than that of the Sun, so the total solar eclipse on the Moon lasts longer than the total solar eclipse on Earth (the same as the total lunar eclipse on Earth).

2) A total solar eclipse on the Moon is observable by half of the Moon (the hemisphere facing the Earth), and a total solar eclipse on the Earth is only observed in a strip-like area. 3) Since the Moon has no atmosphere, the corona of the Sun can be observed during a total eclipse of the Sun on Earth; Conversely, because the Earth has an atmosphere, the Earth's atmosphere can be observed during a total solar eclipse on the Moon, and this atmosphere is exactly red (which is similar to the morning or sunset we observe on Earth). In other words, when there is a total solar eclipse on the Moon (which is the total lunar eclipse on Earth), the half of the Moon facing the Earth is not completely dark, but red like the morning and evening on Earth – this is the Moon in a total eclipse from Earth, which is of course red.

I think it must be spectacular to see the Earth from the moon at this time, it should be a black disk surrounded by a large red halo.

Why were the ancients afraid of the "Blood Moon"? What the hell is it? After reading the knowledge!

Folk rumors: If the moon changes color, there will be disaster. Green is worried about hunger, red is fighting and fighting, yellow is virtue and joy, white is drought and mourning, black is water, and people are sick and die.

Science explains the occurrence of a total solar eclipse on the Moon.

The sky won't fall, the earth won't fall, you can do whatever you have to do.

Hello, there are two ways in which a blood moon can form, the first is that the Earth's atmosphere refracts sunlight, causing only red light to enter the atmosphere. The second is that during a total lunar eclipse, the Moon is in the Earth's umbra, and the red light component of the sun's light is refracted by the Earth's atmosphere, causing the red light to be emitted to the Moon, resulting in a blood moon.

The reason for the existence of a blood moon is that the Earth absorbs the blue and green light of the sun's rays, which have a shorter wavelength, leaving only red light to penetrate.

A Blood Moon, or red moon, usually occurs during a total lunar eclipse. Blood Moons occur once or twice a year, but consecutive April eclipses are very rare, with total lunar eclipses occurring for four consecutive months in two years, only three in 500 years, and the fourth on April 15 and October 8, 2014, and April 4 and September 28, 2015. According to NASA's estimates, the fifth consecutive April eclipse will occur in 2032 and 2033.

If there is a blood moon, there will generally be **, tsunamis, etc., because the moon's magnetic field is shifted, causing changes in the earth's magnetic field, causing physical changes.
