Rare Triple Treat: A Super Blue Blood Moon Eclipse
Skywatchers will get a rare triple treat Jan. 31: a supermoon, a blue moon and a total lunar eclipse. How rare is the event? Even without the supermoon, it's the first blue moon total lunar eclipse in the U.S. since March 1866, less than a year after the Civil War ended, according to EarthSky.org.
