(NJ.COM) -- If there's such a thing as a Super Bowl for amateur astronomers, it's happening in January 2018. The new year is ringing in with two rare "supermoons" — including one that will be a "blue moon" — along with a lunar eclipse. All during the same month.
The first of the two supermoons will appear in the sky on New Year's Day, and the second one will be glowing on Jan. 31. That one will be a "blue moon," because it's the second full moon during the same calendar month.
Such an occurrence happens only once in a blue moon — well, technically, once every two to three years, according to astronomy experts from Space.com.
