Supernova – en kosmisk katastrofe Massiv stjerne som supernova. Den ene type starter som en stjerne med en masse på 7-9 gange vor Sol og derover (en mere præcis nedre grænse kan ikke angives, idet den afhænger af bl.a. stjernens sammensætning af grundstoffer på dannelsestidspunktet), som dør i en gigantisk detonation.Jo større en stjerne er, desto hurtigere løber den tør for brint ...

6 de may. de 2024 · Usually a very dense core is left behind, along with an expanding cloud of hot gas called a nebula. A supernova of a star more than about 10 times the size of our sun may leave behind the densest objects in the universe— black holes. The Crab Nebula is the leftover, or remnant, of a massive star in our Milky Way that died 6,500 light-years away.
