Total Lunar Eclipse Will Be Tomorrow

Tomorrow night will be the first total lunar eclipse of the year over North America. The next one will not be until December 2010. Naturally, it will probably be cloudy here. I will definitely keep checking outside, but I don’t expect to see it.

A lunar eclipse is when the moon moves into the Earth’s shadow. During the time that the moon is fully in the Earth’s shadow, it turns red due to the atmosphere of the Earth. The atmosphere lets red light bend a bit, and some of it hits the moon’s surface. It’s like the sky at sunset, scattering the non-red light the most.
