For centuries a piece of rock about an inch in diameter has been speeding through space at 158,000 mph. It’s part of a dusty trail shed by the Comet Tempel-Tuttle. Every year around November 18th Earth encounters this comet debris in what’s known as the Leonid meteor shower. At 2:18AM this particular meteoroid was vaporized by Earth’s atmosphere in a brilliant flash of light. For 20-30 minutes afterwards a glowing vapor trail hung in the sky, twisting and turning before dispersing. Beneath Medicine Mountain in the Bighorns, the weather was perfect for stargazing this time of year. Most years the Leonids are nothing special, but they have a history. Approximately every 33 years, a denser stream of debris causes meteor rates to skyrocket. Historical accounts describe hundreds of thousands of falling stars filling the entire sky in a meteor storm. Though numbers were low this year, sometimes it only takes one to make your night.
