BBC News - Team sees biggest black holes yet - 0 views

  •  
    "Most massive galaxies, including our own Milky Way, are thought to harbour supermassive black holes at their centres. But these newly discovered black holes are much bigger than would be predicted by extrapolating from observations from their host galaxies. This suggests that the factors influencing the growth of the largest galaxies and their black holes differ from those influencing smaller galaxies. The findings come from observations of two nearby galaxies: NGC 3842 and NGC 4889."

BBC News - Super-Earths 'in the billions' - 1 views

  •  
    "Harps employs an indirect method of detection that infers the existence of orbiting planets from the way their gravity makes a parent star appear to twitch in its motion across the sky. "Our new observations with Harps mean that about 40% of all red dwarf stars have a super-Earth orbiting in the habitable zone where liquid water can exist on the surface of the planet," said team leader Xavier Bonfils from the Observatoire des Sciences de l'Univers de Grenoble, France. "Because red dwarfs are so common - there are about 160 billion of them in the Milky Way - this leads us to the astonishing result that there are tens of billions of these planets in our galaxy alone.""
