Since 2007, astronomers have been aware of a type of interstellar phenomenon known as a rapid radio burst, or FRB for short. They are the emission of radio waves that can generate 100 million times the power of the sun in a matter of milliseconds. Until recently, they were observed only in our outer galaxies. But this past April, astronomers had the first chance to see FSBs appear in the Milky Way (via MIT News).
When astronomers first discovered FRBs more than a decade ago, physicists theorized that they could be created by a special class of neutron stars called magnets emitting a special magnetic field. strong distinction. Neutron stars, if you need to renew, are the remnants of a supernova and see its core collapse on its own. Turns out those doubts may be true. At the end of April, astronomers recorded a series of FRBs they suspect originated from SGR 1935 + 2154, a magnet located about 30,000 light away from Earth. The radio telescope with the clearest view of the phenomenon, Canada’s Hydrogen Intensity Mapping Experiment (CHIME), did so at the edge of its range, leading to some uncertainty about the identity of source.
