Maybe you've heard that tomorrow night there will be a "Super Blue Blood Moon," but you're not entirely sure what all that means.
For the first time in over 150 years, a Blue Moon, Super Moon, and a Lunar Eclipse will all happen at about the same time.
Blue Moon: Two full moons in one calendar month
Blood Moon: When the moon passes into the Earth's shadow (a lunar eclipse, making the moon appear red)
Super Moon: When the moon's perigee coincides with a full moon (making the moon seem larger than normal)
(Perigee: When the moon's orbit is nearest to the earth)
The first full moon of January was New Year's Day, and the second one will be occurring overnight on January 30. That also happens to be the same time as a lunar eclipse, and a "super moon." It's something that hasn't happened since 1866.
For those of us in Wyoming, the eclipse portion won't really begin until 4:48 a.m., peaking around 6:00 a.m. Hopefully the snow we're expected to receive tonight will pass through before then, but NASA will be livestreaming the event from their Armstrong Flight Research Center in Edwards, California; the Griffith Observatory in Los Angeles; and the University of Arizona’s Mt. Lemmon SkyCenter Observatory.
If you are awake and the skies overhead are clear, a tip from NASA about getting the best Super Moon photos: include another object for reference. Whether that's a natural monument like Devils Tower, a building, or even yourself (or the kids, if they're up for school that early!)
