That’s because the Jan. 31 supermoon will coincide with a total lunar eclipse, which will give the moon a reddish glow due to the sunlight reflected by the Earth’s atmosphere. Another nickname will come into play here, as totally eclipsed moons are sometimes called “blood moons.”
But that’s not the only label of Jan. 31’s moon — that full moon also happens to be the second full moon of the month, an event that is often referred to as a “blue moon.” This means the 31st’s supermoon will be a “super blue blood” moon, according to NASA.
It may seem like the 31st’s moon is the lunar spectacle to keep your eyes on, but don’t forget about the one on New Year’s Day — it could be a great way to commemorate the start of 2018.
“The supermoons are a great opportunity for people to start looking at the Moon, not just that once but every chance they have!” said Noah Petro, a research scientist from NASA’s Goddard Space Flight Center, according to the space agency.
