Non solo esplosioni di supernove. Scoperto un nuovo tipo di esplosione stellare, la millinova è cento volte più luminosa del Sole. Si allunga la lista delle esplosioni stellari: dopo le più celebri nova, supernova e kilonova, ora arriva anche la millinova, una nuova tipologia cento volte più luminosa del Sole ma circa mille volte meno di una classica nova.

Nova vs Supernova

#Supernova is the last dying gasp of a star as it goes dark.

A #nova, on the other hand, requires two stars. One star is always a white dwarf, while the other is usually a red giant.

#Hypernovas are supernovas that achieve a certain size and brightness. Usually, they're about 10 or more times brighter than a standard supernova. Another type, an extremely rare #kilonova occurs when two neutron stars collide, releasing an incredible gravitational wave.
