Is there a red moon in this world, and why is the moon red?

A: 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.

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, and it should be a black disk :) surrounded by a big red halo

The moon itself does not emit light. Not to mention the red moon, not even the white moon.

If you want to see a red moon, take a piece of red glass and see through it what color it is.

The moon does look a little reddish during a lunar eclipse.

1. The red moon is the most yin and cold, indicating that the world is weak in righteousness, evil is strong, resentful, and angry.

Strong; The wind and clouds change drastically, and the mountains and rivers are sorrowful; The world is in turmoil, and fires are everywhere.

2. Therefore, it is called: blood moon.

Europeans believe that a blood moon awakens dark magic! Indians believe that a blood moon is a harbinger of disaster.

3. The moon rising in the early morning is orange-red; During a total lunar eclipse, the moon is seen by the public as red.
