Astronomers say fast radio burst detected in the Milky Way produced by highly magnetized star

The video explores the connection between the Milky Way and a magnetar named SGR 1935+2154, located 30,2616 light years from Earth. It discusses fast radio bursts, which are high-energy blasts that last milliseconds but release energy equivalent to 80 years of solar output. Magnetars, highly magnetized neutron stars, are described as dense and rapidly rotating, with intense magnetic fields. These characteristics allow them to store energy that could potentially power fast radio bursts through star quakes caused by magnetic field stresses.
