Get ready for a wild Labor Day sky show! A rare 'cannibal' solar storm is barreling toward Earth, and it could light up the northern U.S. with stunning auroras—even in places that don’t usually see them. The action starts late Sept. 1 and peaks Sept. 2, so keep your eyes peeled (and your cameras ready). Bonus: If clouds ruin your view one night, you might get another shot the next! #Science #AuroraBorealis #NorthernLights
