Massive star challenges black hole theory
• Using ESO’s Very Large Telescope, European astronomers have for the first time demonstrated that a magnetar — an unusual type of neutron star — was formed from a star with at least 40 times as much mass as the Sun. Simon Clark from the Open University led the team that made the discovery and he tells Quentin what it means for astronomy.
