Comets are mysterious members of our solar system. ISON seemed so bright when it was discovered it excited yet another “comet of the century is coming” craze. Alas, predictions were far off, though there is still a chance for an impressive view if ISON survives its trip around the Sun. You can check out some neat pictures here http://bit.ly/17bI8Jn and in the related “gallery”.
The unpredictable nature of comets makes them a good topic for science fiction. I’m hoping to include an encounter with a comet in my next novel.
