Comet ISON

Comet ISON (C/2012 S1) was discovered by photos taken by Vitali Nevski and Artyom Novichonok from Russia using the International Scientific Optical Network telescope (ISON). Astronomers observe that the comet is so bright, it will be visible in daylight.

It is estimated to pass by our Sun at less than 2,000,000 km on 28 November 2013.
