WATCH THIS: Sky-gazers can catch a triple space-tacular event tonight with a full "snow" moon, a lunar eclipse and then a comet sighting. Tonight (Friday), the full moon will pass into the Earth’s outer shadow, resulting in a partial eclipse. Look for it starting at 5:32 p.m. eastern time. It will last for about four hours. Then, early Saturday morning, a comet named 45P will zoom past our planet. It will be only 7.7 million miles away, which is closer than these encounters usually come.
