Depends on the supernova.

This one: http://www.universetoday.com/2008/07...-burst-hybrid/

If memory serves, the gamma rays from this sunburst was big enough to wipe out any potential life in its galaxy, and the four surrounding galaxies. It produced a measurable surge of gamma rays here on earth, in our own galaxy. Heck, it might have been the inspiration for Abrams' supernova.

Fortunately there are no such stars in our galaxy, or in the galaxies around us. Neat, huh?
