NASA's solar observing fleet to watch Comet ISON's journey around the sun
It began in the Oort cloud, almost a light year away. It has traveled for over a million years. It has almost reached the star that has pulled it steadily forward for so long. On Thanksgiving Day, Nov. 28, 2013, Comet ISON will finally sling shot around the sun. Here its inward journey through the solar system will end -- either because it will break up due to intense heat and gravity of the sun, or because, still intact, it speeds back away, never to return. (2013-11-22)
