So far, SGR 1806-20 is the most magnetized object known in the universe.

Our universe contains a variety of phenomena that will keep the astrophysicists busy for several years. Among these strange things, there is undoubtedly the most magnetized object known to date. It is a special kind of star called  magnetar SGR 1806-20. It is a very dense neutron star with a diameter of only 20 km. It is located in the Sagittarius constellation. A magnetar is the remnant of a supernova that has exploded. In this type of star, the crust and its magnetic field are closely interrelated. The powerful burst of X-rays and gamma rays that the Earth received on December 27, 2004 was probably caused by a crack in the crust which in turn has destabilized the strong magnetic field of the star. The  reconnection of magnetic lines and the reconfiguration of the magnetic field have propelled a massive amount of gamma rays. Due to their high density and the enormous power of their magnetic field, they are one of the most interesting objects to study.
