Nyheter från ESO
16 oktober 2017

ESO:s många teleskop i Chile har registrerat det första synliga ljuset från en källa för gravitationsvågor. De historiska observationerna tyder på att den unika ljuskällan skapats av två neutronstjärnor som slagits samman. Tack vare de kataklysmiska efterdyningar till sådana sammanslagningar sprids tunga grundämnen som guld och platina genom universum, tror forskare. Upptäckten av denna länge förutspådda fenomen, en så kallad kilonova, ger också det starkaste beviset hittills att korta gammablixtar skapas när neutronstjärnor går samman. Rönen publiceras i flera forskningsartiklar i bland annat i tidskriften Nature.
