  • December 20: The Winter Solstice

Our December meeting will be on the evening of the 20th, just one day before the winter solstice. In winter at our latitude, the Sun stays low to the horizon and days are short, but the solstice marks the turning point. From then onward, days begin to lengthen again and the Sun rises higher in the sky each day. Mankind has celebrated this turning point for millennia as a time of rebirth and hope. Jerry Oltion will talk about the physical as well as the sociological aspects of the winter solstice. Why does the Sun dip so low in the sky in winter? What causes the seasons? Will they always be the same, or will astronomical alignments change enough to alter the seasons as we know them? Do other planets in our solar system have seasons? Come to our December meeting and find out. Meetings are held on the third Thursday of every month at the Science Center planetarium. We start promptly at 7:00, so come early to visit and get a seat.
