There’s a total lunar eclipse tonight (not that I’ll get to see it because of our craptacular weather). If the weather is clear in your area, you should check it out. It will be the last total lunar eclipse until December 2010. A lunar eclipse only happens with a full moon :) and the moon passes through some portion of the earth’s shadow. The earth’s shadow gives the moon a red color due to atmosphere, but if you catch the eclipse at the beginning, the moon can sometimes look turquoise.
