In this picture, called a coronagraph, the bright light of the sun itself is blocked so the structures around it are visible. The comet is seen in the lower right; a giant cloud of solar material, called a coronal mass ejection or CME, is seen billowing out under the sun.

Comet ISON, which began its trip from the Oort cloud region of our solar system, reached its closest approach to the sun on Thanksgiving Day, skimming just 730,000 miles above the sun's surface.

NASA tracked Comet ISON's journey and hosted events to discuss what the public worldwide might see as the comet traversed the sun.
