Mitä eroa on supernovalla ja novalla?
Supernovae are more energetic than novae. 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 Walter Baade and Fritz Zwicky in 1931.
