March's full moon is called the "Worm Moon," according to the Farmer's Almanac, which has documented the history of how full moons are named. Moons that take on these reddish hues during a total lunar eclipse are called " Blood Moons ." The combined nicknames have resulted in some calling it the " Blood Worm Moon ."

"Lunar eclipse is if you're on the side of the Earth that's facing the full moon, you will see the eclipse. The side of the Earth, so, in that sense, it's not rare. (We) get one every couple of years," astrophysicist Neil deGrasse Tyson said March 14 on TODAY. Tyson also explained just how the moon turns the shade of red it does.
