A total lunar eclipse is coming on Jan. 31, but that’s not all.

It’ll also be a blue moon and a supermoon, according to The Weather Channel.

What’s a blue moon?

It is a phenomenon whereby the moon appears bluish owing to smoke or dust particles in the atmosphere.

What’s a supermoon?

It is the phenomenon when the moon appears particularly large in the sky due to the coincidence of its closest approach to the earth (the perigee) with a full (or new) moon.
