### ameriti$h What is catastrophic nova?Why have cosmologist chosen this characteristic for nova? 2. Jun 17, 2007 ### George Jones Staff Emeritus I'm not sure what you mean. Do you mean catastrophic supernovae and their use in cosmology? 3. Jun 17, 2007 ### jonegil you prob'ly mean catastrophic supernovae...if you do, a catastrophic supernova is a very violent explosion of a star that will end up in a black hole or in a neutron star 4.
