For første gang er et nydannet tungt grundstof, nemlig strontium fundet i rummet i efterdønningerne af en kollision imellem to neutronstjerner. Den nye opdagelse er gjort med ESOs X-shooterspektrograf på Very Large Telescope (VLT), og den offentliggøres idag, 23. oktober 2019 i tidsskriftet Nature. Opdagelsen er en bekræftelse af, at de tunge grundstoffer i Universet kan dannes ved sammenstød af neutronstjerner. Dermed har vi fundet en af de manglende brikker til puslespillet om dannelsen af de grundstoffer, vi kender. Og der er en særlig grund til at fejre opdagelsen med fyrværkeri, for det er strontiumsalt, som giver den flotte røde farve!
