    Latest Supernovae - http://www.rochesterastronomy.org/snimages/

    Some images show supernovaes outshining galaxies.


    The energy release from the thermonuclear burning (~1044 J) - from http://en.wikipedia.org/wiki/Supernova, which also contains statements

    Just as an FYI, 1 foe = 1E51 ergs = 1E44 joules.

    Just some bragging here, I actually took the spectra for SN 2005df (first on the list Astronuc provided)a couple of days after it was discovered at Siding Springs observatory. The spectra provided the information necessary to determine that it was a type 1a supernova.
