Comet ISON Now Visible to Naked Eye After Outburst - Video

The much-anticipated Comet ISON is now visible to the naked eye according to reports from many observers.

Comet ISON — the potential "comet of the century" — has suddenly brightened in an outburst of activity with just two weeks to go before it grazes the surface of the sun.

In recent months, Comet ISON has repeatedly befuddled forecasters trying to anticipate just how bright it will ultimately become. But earlier this week, the comet's brightening trend again seemed to sputtering and stalling, but more recent observations suggest a sudden and radical upsurge in brightness.
