A dead star is flashing radio waves every 8 minutes, and its partner looks a lot like the sun

Since 2022, astronomers have been puzzling over a new kind of cosmic object called long-period radio transients. These are objects that emit bright flashes of radio waves into space every few minutes to every few hours. Some have been traced back to binary systems consisting of a small, dim, cool st...
