Take a look up at the sky tonight and feast your eyes on a "blood moon." This will be the fourth and final sight of a blood moon over the past two years.
If you don't catch it tonight, the next one will be in 2033.
However, the stars are aligning to make tonight even more special. Tonight is not only a blood moon, it's also a super moon and a lunar eclipse, all in one.
The eclipse will begin around 8:11 PM, but the total eclipse will begin to be visible around 10:11 PM in the Eastern time zone. The eclipse will peak at approximately 10:47 PM.
The moon will be at its closest point since 1982, making it a supermoon.
The blood moon phenomenon comes from particles in the earth's atmosphere filtering the light reflected off the moon, making it appear dark red to the human eye.
Over the span of the hour-long eclipse, the moon will first get dimmer, then it will redden until a black shadow appears before it dims one final time.
