How is the blood moon formed?

Now, from a scientific point of view, how did the red moon come from? The red moon is a spectacle that only occurs during an eclipse. When the earth is in the middle and the sun and the moon are on both sides, if the earth blocks part of the sunlight for the moon, it is called a partial eclipse in which the moon blocks all the sunlight, which is called a total lunar eclipse. The sun shines into the earth, and the thick atmosphere absorbs all the purple, blue, green and yellow light, only reflecting red light, so the moon looks red. However, during the total lunar eclipse, although the earth blocked all the sunlight, both the total lunar eclipse and the blood moon occurred in the period when the moon was closest to the earth, that is, the super red moon. Therefore, this opportunity is really hard to get.
