If the weather is clear where you live on Tuesday evening (Dec. 17), look low above the east-northeast horizon at around 8:00 p.m. local standard time and you'll see the waning gibbous moon, 89% illuminated, accompanied by a very bright and colorful star directly below it and two bright stars will above it.
The two stars hovering well above the moon mark the heads of Gemini, the Twins. Pollux will be closest to the moon, while the somewhat dimmer star Castor will lie just above it.
