What happens when a solar storm collides with a comet? Back in 2007, a coronal mass ejection ripped the tail off of Comet Encke. (You can watch that happen in an awesome NASA gif.) Tomorrow, Comet ISON is due to fly closer to the Sun than Encke, during a much more active time in the solar cycle. Scientists are anticipating an awesome collision, like spectators at a demolition derby.
