TONIGHT, TONIGHT, WON'T BE JUST ANY NIGHT...TONIGHT THERE WILL BE
A rare sky spectacle will occur Monday night that (probably) won't happen again for years: A full moon that can be called both a supermoon and blue moon will grace the night skies over the U.S.
Dubbed a "super blue moon," the rare combination occurs when the different cycles of blue and supermoons happen to align on the calendar, said NASA's Noah Petro, Lunar Reconnaissance Orbiter project scientist.
