CRESCENT MOON JOINS THE GREAT CONJUNCTION: When the sun goes down tonight, step outside and look southwest. A whisper-thin crescent Moon is photo-bombing the Great Conjunction of Jupiter and Saturn. For the next two nights, the Moon will glide by the giant planets, which are themselves on the verge of their finest pairing in hundreds of years.
