Radio waves observed from neutron star 'silent' for 10 years

A UK-German team of astronomers has observed bright flashes of radio waves from a neutron star with extremely strong magnetic field, or 'magnetar', which was inactive for the past 10 years. Astronomers revealed the magnetar in question is the first of only four known such objects to emit radio pulsations. Only 23 magnetars have been identified till date, astronomers added.
