A cosmic event not seen in 36 years -- a rare "super blood blue moon" -- may be glimpsed January 31 in parts of western North America, Asia, the Middle East, Russia and Australia.The event is causing a buzz because it combines three unusual lunar events -- an extra big super moon, a blue moon and a total lunar eclipse."It's an astronomical trifecta," said Kelly Beatty, a senior editor at Sky and Telescope magazine.
