As nouns the difference between supernova and bosenova

is that supernova is a star which explodes, increasing its brightness to typically a billion times that of our sun, though attenuated by the great distance from our sun. Some leave only debris (Type I); others fade to invisibility as neutron stars (Type II) while bosenova is a very small, supernova-like explosion, which can be induced in a Bose-Einstein condensate by suitably changing its magnetic field.
