Why is the Moon red like blood when the total lunar eclipse occurs?

The ultimate eclipse is also called the Blood Moon, an astronomical phenomenon that occurs when the Earth completely shines light from the Sun to the Moon (the Sun, Earth and Moon are arranged in a perfectly straight line). for).

2. Why didn't NASA intend to return to the Moon?

Our Earth is large enough to cover a sun three times the size of the Sun today. But why when the total eclipse occurs, the moon that we observed from the Earth is not black but is colored from bright orange to red like blood?

According to scientists' explanation, when the Earth is at the center of the Sun and Moon, rays from the Sun can still "glide" over the surface of the Earth and reflect on the Moon.

Light rays are reflected by the Earth's red-colored atmosphere. Specifically, light rays from the Sun hit the Earth's atmosphere and then go back to the Moon and create a red color similar to the red of dawn.

At that time, Earth's atmosphere acted like a filter, all short-wavelength green light was filtered out, only red / orange light could reach the Moon.

According to scientists at NASA, the color of the Moon when a total eclipse occurs occurs largely because the "filter" is the atmosphere and Earth's unusual light sources, such as volcanoes. The eruption will make the Moon darker than normal.

During the lunar eclipse, the moon will have different colors, gradually changing from gray to orange and finally amber.
