Great Comets from Humble Origins & Eyes on ISON Dr. Frank Summers, Space Telescope Science Institute
Comets can be one of the most amazing sights in the heavens, with bright, naked-eye comas and tails stretching across half the sky. The most spectacular comet appearances are called "great" comets, but such an occurrence is infrequent enough that it is also nicknamed a "comet of the century." In preparation for the Thanksgiving Day perihelion passage of Comet ISON, along with its great possibilities, it's a proper time to examine the humble origins, from the most rural parts of the solar system, of these briefly blazing celestial visitors.
