If the comet ISON makes it out intact from its encounter with the Sun this week, the Earth is in for a potentially dazzling sight in the December night skies as it passes close to Earth and out further into the solar system. But scientists are starting to emphasize the "if" in that sentence a bit more today, after some observed what appears to be a sudden drop in the light emitted from ISON, along with an apparent explosion of dust production. Those observations could mean that the comet broke apart during its approach to the sun. This, however, does not mean that ISON is definitely gone.
