Lunar Eclipse
February 21, 2008 by Lemur King
Tonight was a lunar eclipse. What happens is described here: American Sinstitute of Physics Explanation … so I won’t go into it.
What’s cool about it is the “sunset effect” where the moon sees the same kind of reddened sky that we see when the sun is setting. But, rather than a chord through one hemisphere at low angle, the moon saw it through a chord across two hemispheres - I wonder what it looks like (yeah, I know.. red).
The question I have is, would an astronaut on the moon have a chance of seeing a green flash? I’ll be asking around - if you know the answer just shout it right out!
