Comet ISOM is having some electrical impact or discharge (see video below) as is whips around mars. The big question really becomes will will be the outcome when it moves closer to other celestial bodies especially the sun.
The promising Comet ISON, now less than two months away from a close encounter with the sun, is making a close approach to another member of the solar system : the planet Mars.
In the night sky, Comet ISON is currently located about 2 degrees above and to the left of Mars. Both Mars and ISON are in the constellation of Leo, not far to the west (right) of the famous backward-question mark configuration of stars popularly known as the Sickle.
Astronomers measure the brightness of night sky objects on a magnitude scale, with lower numbers denoting brighter objects. Mars is currently not particularly bright, shining at magnitude +1.6, falling into the ranks of a second magnitude star. Comet ISON, meanwhile, shines at about magnitude +12, making it roughly 600 times fainter than the dimmest star that can be seen the unaided eye. [Photos of Comet ISON: A Potentially Great Comet]
