What to look out, and up, for in December. We start with the broad constellation of Gemini and an easy binary star, a planetary nebula and a group of star clusters for astronomy beginners to find, before emabarking on a spot of exogazing! Next up is the return of resplendent Jupiter and Venus to our skies. We bring you the phases and conjunctions of the moon and the Geminid meteor shower in December. Then we round up the best of the deep sky offerings for the month in the winter constellations of Orion, Eridanus & Lepus.
