Go outside, and look up at the moon. That is a Super Blood Moon.
Scientifically speaking, a Supermoon is when the Moon passes closest to the Earth in its orbit, making it seem 14% larger than usual, and significantly brighter.
Then the blood moon arises from a lunar eclipse, where the earth blocks the sun partially from the moon, so that only some of the light touches the moon and causes it to shine slightly LESS bright, the result when they happen together (the last one in, I think 1982, 88 or something) being a blood red moon that is much larger than usual. We won't see another one until 2033.
