What? A total eclipse of the moon? Yes! When? Wednesday evening, February 20th, 2008. This is the last chance to see one in the United States until 2010. Go out after the sun sets and watch the glory begin around 8:43 PM EST. Totality begins at 10:01 PM. Weather permitting, you will see red, caused by the scattering of blue light out of your sight line by the stratosphere, and possibly also a turquoise flash, caused by light passing through the upper stratosphere, through the ozone layer, which has the opposite effect, absorbing red light, making it look blue.

That was a very nice explanation for why we see the moon red during the total eclipse and why we might see turquoise.
