Washington, D.C. – Anticipation is building as Comet ISON plunges into the inner solar system for a close encounter with the sun in November 2013. Blasted at point-blank range by solar radiation, the sungrazer will likely become one of the finest comets in many years.
When NASA’s Swift spacecraft observed the comet in January 2013, it was still near the orbit of Jupiter, but already very active. More than 112,000 pounds of dust were spewing from the comet’s nucleus every minute.
It turns out, some of that dust might end up on Earth .... http://www.clarksvilleonline.com
