I was just wondering why the moon turns red during a lunar eclipse
It is because our dear atmosphere acts as a light filtering system, bending red wavelengths towards our Earth, while keeping out the blue and the rest of the colour wavelengths, scaterring them in all directions, thus our eyes perceived the moon to be red. That is similar to the reason for sunsets and sunrises to be red too.
the atmosphere filters blue light and the indirect light the reaches the moon gives off and orange or reddish tint... depending on how much dust and clouds in the atomosphere
The atmosphere bends sunlight so that it seems red.
