Apparently some folks are concerned that seeing a "blood moon"means the earth is going to end or something like that.While I have complete respect to anyone and everyone's religious beliefs, this time science can come to the rescue.
There is a full lunar eclipse tonight. This means that the moon, the Earth and the Sun are all lined up with the Earth in the middle - the moon is in the Earth's umbra, or shadow. The moon isn't completely invisible though - because of the angle at which the light from the sun passes through the Earth's atmosphere, the moon appears reddish. This is where the name "blood moon"comes from. There will be another total lunar eclipse sometime this autumn - I forget exactly when. There are between two and five lunar eclipses each year, although not all of them are full eclipses.
Sometimes the full moon in October is called the Blood Moon. This, like another traditional name, the Hunters Moon, is referring to the fact that October is when animals were slain to prepare for the long winter ahead.
