Radio-bursting magnetar, illustration. Magnetar SGR 1935+2154 is a highly magnetised remnant of a dead star about 30, 000 light years away from Earth. Magnetars have intense magnetic fields. When they become active they can produce short bursts of high energy radiation. In April 2020, SGR 1935+2154 became active again and emitted not only a short burst of X-ray radiation but radio waves as well. This was the first Fast Radio Burst to be seen in our galaxy and the first to be linked to a magnetar. | |
