Cosmic Flashes come in all Different Sizes

Fast radio bursts from magnetar SGR 1935+2154 (illustration)
On May 24, four European telescopes took part in the global effort to understand mysterious cosmic flashes. The telescopes captured flashes of radio waves from an extreme, magnetised star in our galaxy. All are shown in this illustration. â€‹â€‹â€‹â€‹â€‹ â€‹Danielle Futselaar, artsource.nl

By studying the site of a spectacular stellar explosion seen in April 2020, a Chalmers-led team of scientists have used four European radio telescopes to confirm that astronomy’s most exciting puzzle is about to be solved. Fast radio bursts, unpredictable millisecond-long radio signals seen at huge distances across the universe, are generated by extreme stars called magnetars — and are astonishingly diverse in brightness.

For over a decade, the phenomenon known as fast radio bursts has excited and...
