If you have any interest at all in astronomy, physics, or just a curious mind, I'd encourage you to look to the SW portion of the sky tonight 30-60 minutes after sunset to see the great conjunction of Saturn and Jupiter. A conjunction, in astronomy, is when two celestial bodies appear from earth to be very close together (although, of course, they are still very far apart). A "great conjunction" refers to a conjunction of the two biggest planets in our solar system. This will be the closest the two planets will appear in the night sky in about 800 years, so it's truly a once in a lifetime astronomical event.
To the unaided eye, they will appear as if they are a close double star in the sky, and through a telescope, they will appear in the same field of view. I'll be out in the desert with the wife and two scopes, an 80mm refractor, and a 17.5 inch reflector. I had the refractor out on the deck tonight, and it was really cool to see both the cloud bands of Jupiter and the rings of Saturn in the same telescope view. Check it out, and if you have any sort of scope or binoculars, use those as well!
People are calling this a "Christmas star," which is kind of a misnomer, as they are planets, not stars, but some astronomers, such as Johannes Kepler, posited that the star of Bethlehem that is referred in the story of the Magi visit to the newborn Jesus might have been a great conjunction that occurred around that time!
