  2. Comets are Notoriously Unpredictable!

  3. What is Comet ISON? ISON was discovered by Russian astronomers VitaliNevski and ArtyomNovichonok in September 2012. It's named after their night-sky survey program, the International Scientific Optical Network. Now near Jupiter, this sun-grazing comet may be the cosmic event of the year.
