You may have heard of Halley's comet visible in the 1980s. It's one of the best-known of the short-period comets, and is visible from Earth every 75–76 years. Others may be brighter but appear only once in thousands of years. Once such comet recently discovered may blaze brilliantly in the sky in 2013.
The new comet, named C/2012 S1 (ISON) was discovered this year by the International Scientific Optical Network in Russia.
It's currently too far away and too dim to be seen without special optics, but will become more visible to amateur astronomers in the coming months.
What's so interesting about this comet is astronomers believe it may be brighter than the full moon as it shoots acros the sky late next year (2013).
