The full moon on Wednesday will be the second in a month, making it a blue moon. It'll be at the part of the moon's orbit that defines a supermoon. And there will be a total lunar eclipse.
The total lunar eclipse is the most exciting for astronomers — it can give the moon a reddish tint, which is why it's sometimes called a blood moon.
To catch the eclipse, you'll need to look up at a certain time: early in the morning in the US, or later that night in other parts of the world.
Early Wednesday, those in certain parts of the world will be able to look up at the sky and see what you could call a "super blue blood moon."
A full moon at the part of the moon's orbit closest to Earth is known as a supermoon. The full moon on Wednesday will also be the second in a calendar month, commonly referred to as a blue moon by NASA and others.
