It's a triple-treat for sky-lovers overnight into Wednesday as a super blue blood moon rises over the great state of Colorado (and the world).
So what exactly is this thing?
A blue moon — which occurs about every 2½ years — is another term for the second full moon in a single calendar month. January's first full moon occurred Jan. 1.
The exact moment of the full moon for us will be 6:37 a.m. Wednesday morning - so make sure to get up a little early for work!
As for the total lunar eclipse, it will be visible early in the morning of Jan. 31 from western North America across the Pacific to eastern Asia, NASA said.
The full moon will take on a dark, reddish appearance during the eclipse, so another word to describe it is a blood moon. Adding to the naming confusion, this full moon was also known as the "snow moon" by some Native American tribes.
Finally, a supermoon occurs when the full moon is at the closest point of its orbit to the Earth, which is also called the perigee.
That makes the moon look extra-close and extra bright — up to 14% bigger and 30% brighter than a full moon at its farthest point from Earth, known as the apogee, NASA said.
