Welcome to the night sky report for December 2020 -- Your guide to the constellations, deep sky objects, planets, and celestial events that are observable during the month. Step outside on a cold December night when the stars shine bright to find the Big Dipper, Cassiopeia, and Cepheus. They will help you locate a binary star system, a fan-shaped open star cluster, and a variable star. Also this month, catch the Geminids meteor shower. Then see Jupiter and Saturn come together in a conjunction to form a "double planet." Just after sunset on the evening of December 21st, Jupiter and Saturn will appear closer together in Earth’s night sky than they have since the year 1226 -- That’s 800 years ago during the Middle Ages. Is this like the Star of Bethlehem? No, not really -- I realize it is just two planets coming together in the sky (not a star), it’s pointing west instead of east, and it is a few days early for Christmas, but I couldn’t resist making the connection, so work with me here. (Interesting side fact, some have speculated that the true Star of Bethlehem could have been the conjunction of Jupiter and Venus near the bright star Regulus that occurred in the year 2 BC). The night sky is truly a celestial showcase. Get outside and explore its wonders from your own backyard.
