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.

Wat is een kilonova?

Een kilonova is een heldere explosie van elektromagnetische straling die optreedt wanneer twee neutronensterren of een neutronenster en een zwart gat met stellaire massa botsen en samensmelten.
