Why A Total Lunar Eclipse is Red

 

According to atmospheric scientist Richard Keen of the University of Colorado, “During a lunar eclipse, most of the light illuminating the moon passes through the stratosphere where it is reddened by scattering. If the stratosphere is loaded with dust from volcanic eruptions, the eclipse will be dark; a clear stratosphere, on the other hand, produces a brighter eclipse. At the moment, the stratosphere is mostly clear with little input from recent volcanoes.” Also, as light passes by Earth’s atmosphere, short wavelengths, like blue, are scattered. By the time light finished its trip to the moon, only longer wavelengths, like red, remain. This is why the moon turns red during an eclipse!

  1. Dear Anthony–I promised my boyfriend that I would wink at the moon while thinking of him while he was gone these past few days. I can’t find it. I’m in The Woodlands. It’s not new moon time. Help!

  2. It’s just what I wanted. A great contribution. I subscribe to the blog, if all these posts are worth it and receive email updates.
