Comet ISON is a sungrazing comet on its maiden voyage to the inner solar system, and has the potential to put on quite a show in 2013 if it survives its close encounter with the Sun.
ISONblog draws on the expertise of the astronomers and staff of the Space Telescope Science Institute, home of the science mission of the Hubble Space Telescope, to bring you unique analysis and original images of Comet ISON during its visit to our skies.
