Why is the lunar eclipse red?

Answer 1

Red light has the least energy of all the visible spectrum.

When the moon passes the oppersite side of earth to the sun (lunar eclipse) the earths atmosphere acts like a huge prism.

As we all remember from science at school when light enters a prism the red light bends more than the blue light. The red light is bent around the earth and goes on to light the moon. The blue light is bent a little but not enough to hit the moon.

Answer 2

The redness is caused by the light of sun shining through Earth's atmosphere. Partially it is due to the way light is scattered, meaning reddish light reaches the moon. We get similar effects at sunset. Also there is a lot of dirt and dust in the Earth's atmosphere, which affects the light.

Answer 3

Answer 5

Bending or refracting sunlight into the shadow causes the Moon to have this colour .

Answer 6

The Moon looks red during a Lunar Eclipse because of raw pigmenting of light during an eclipse, it's scattered off the light from the sun, so it just looks red to us.
