The Gran Telescopio CANARIAS (GTC) has observed an uncommon neutron star. Classified as magnetar, its nature is as peculiar as its official name: SGR 0418+5729. The observations at the largest optical telescope of the world reached an unprecedented depth at optical wavelengths for this kind of sources, helping in constraining the physical properties of this celestial body characterized by extremely strong magnetic fields.
