Comet ISON Fizzles

Comet ISON Fizzles As It Rounds the Sun

　Several solar observatories watched the comet throughout its closest approach to the sun, known as perihelion, on Nov. 28. While the fate of the comet is not yet established, it is likely that it did not survive the trip.

　"We didn't see Comet ISON in SDO," said Dean Pesnell, project scientist for NASA's Solar Dynamics Observatory. "So we think it must have broken up and evaporated before it reached perihelion."　NASA HP
