The sky abounds with analogies to things terrestrial. (After all, the starry heavens were the story and history books of the ancients.) In next month’s installment of this column, we’ll be exploring a celestial campfire. Here we discuss a most colorful and fascinating device with which we’re all familiar — the kaleidoscope.

Sky Talk December 2009: The Geminid Meteor Shower

December brings skywatchers one of the year’s richest and most dependable displays of “shooting stars” — the Geminids. They’re named for the constellation from which they appear to radiate or “shoot” across the sky.
