NEW YEARS COMET: Tonight, after sunset, take your binoculars outside and scan the sky right above your head. You may find a little emerald fuzzball--Comet 8P/Tuttle. The comet is making its closest approach to Earth (24 million miles) on Jan. 1st and 2nd. Shining like a ~6th magnitude star, it is barely visible to the unaided eye, but a fine target for binoculars and backyard telescopes.
