Predictably enough, they're calling it the “Christmas Star”; actually, of course, it's neither.
Once in every 800 years, Jupiter and Saturn meet in the sky and kiss. Seen from Earth, they will appear to join and become one. This time around, this Great Marriage occurs—of all the well-omened days of the year—on the day of the Winter Solstice.
Let me be frank: after this dark, dark year, we'll take whatever omens we can get.
Winter is Sky Time. The leaves come down, and the heavens open up. Historically, here in Minnesota, December is the year's cloudiest month, but this year has brought us a succession of clear, fair days of long, slanting Sunlight. These last Sunrises of the waning year have been spectacular, and our Northern nights have been alive with Northern Lights, the dancing daughters of Earth and Sun.
You yourself can witness this 800-year Wonder, this Great Rite in the Sky, wherever you are.
