If you"re lucky enough to find yourself under a cloudless sky tonight, you"ll be able to see one of our solar system"s great wonders, a full lunar eclipse, also known as a "blood moon." The spooky nickname derives from the reddish hue the moon takes on when Earth casts its shadow upon it. Featured here is a blood moon over the Swiss Alps. A full lunar eclipse occurs when the Earth and moon align perfectly with the sun, and the moon falls directly behind Earth"s shadow. When Earth falls behind the moon"s shadow, a solar eclipse occurs.
