Why the moon turns red not black in lunar eclipse?

Answer 1

Because the atmosphere of the earth acts like a lens and refracts the sunlight around the edges of the earth to shine on the moon. The red color comes from the atmosphere eliminating the blue light.

Answer 2

For the same reason that the sun appears red at sunset.

You're seeing atmosphere -filtered light in this case, relected

as well as refracted.

Answer 3

Charles is right. Just a note that red is the longest visible wavelength, which is what happens to light from the sun as it "curves" around the moon to reach our eyes.

Answer 4

Answer from Charles is all correct and nothing to add
