Starwatch: look either side of the moon to find Gemini, the twins

The constellation, one of the 12 zodiacal patterns, is between Ursa Major and Orion in the northern hemisphere

The waning gibbous moon this week will guide you to the heart of the constellation Gemini, the twins.

In the northern hemisphere, Gemini sits between the well-known constellations of Ursa Major, the great bear, to the north and Orion, the hunter, to the south. Sandwiched between these two obvious star patterns, Gemini can be easy to overlook.
