Dypeste bilder av Cloud-9 viser ingen stjerner, styrker teorien om mørk galakse

18 kilder
  • Nye HiPERCAM-observasjoner ved Gran Telescopio Canarias fant ingen stjerneemisjon i Cloud-9, noe som begrenser dens mulige stjernemasse til kun 16 000 solmasser.
  • Cloud-9, en hydrogengassky nær galaksen Messier 94, er den fremste kandidaten for en teoretisk "mørk galakse" som nesten utelukkende består av mørk materie.
  • Funnene, som er akseptert for publisering i Research Notes of the American Astronomical Society, gir sjelden empirisk støtte til en sentral prediksjon i Lambda-CDM-modellen.
