Watch tonight's lunar eclipse
Forget going to see "Gravity," tonight the sky will give a show of its own as lunar eclipse will be visible to certain parts of the world. People in the eastern parts of North and South America, western Asia, Africa or Europe will be able to glimpse the moon passing into the Earth's outer shadow. At approximately 7:50pm EDT, the Earth's shadow called a penumbra will cover more than two-thirds of the lunar disk. The online Slooh Space Camera will air a live broadcast online of the four-hour event starting at 2:45 pm EDT.
