In [[Latin]], Nova means "new", referring astronomically to what appears to be a temporary new bright star. Adding the prefix "super-" distinguishes supernovae from ordinary novae, which are far less [[luminous]]. The word supernova was coined by [https://en.wikipedia.org/wiki/Walter_Baade Walter Baade] and [https://en.wikipedia.org/wiki/Fritz_Zwicky Fritz Zwicky] in 1931.
