Vagabonds of the night sky
By Sreejit Nair | February 7, 2002From the musings of the ancient Chinese to the construction of the modern Hubble Telescope, space always has fascinated the human mind. Through NASA's Comet Nuclear Tour mission, scientists now have an unparalleled opportunity to study what some consider the most striking objects in the sky. The mission's goal is to catch a glimpse of the inner workings and complex structure of comets, the flying balls of dust and ice that glimmer in the night, according to Laura Lautz, NASA's education and public outreach coordinator. "Comets are basically bodies in the solar system identified by their characteristic tails," said Ken Siedelmann, a University professor of astronomy who conducts research on the solar system and is considered an expert on comets.
