If all goes to plan, my research colleagues and I will have front row seats to spectacular New Year fireworks. These are not the artificial bangs and whistles that shoot a few hundred yards into the sky, but the awe-inspiring impact of cosmic dust moving at astronomical speeds. These bits of comet dust travel through space faster than Santa's sled, spanning the distance from Los Angeles to New York in a mere minute and a half. When they hit Earth, the impact of a grain of sand shines so brightly it can be seen for hundreds of miles around. They are called "meteors."
