Mysterious repeating fast radio burst traced to nearby galaxy - CNN - 0 views

Astronomers have traced the signal of an enigmatic repeating fast radio burst for only the second time -- and it's in a spiral galaxy similar to our own, not so far away.
-
Multiple individual fast radio bursts in past years have been traced back to their sources in other galaxies, although those have yet to shed light on what created them.But this newly discovered repeating FRB has a different source from the first one that was found in 2019, deepening the mystery of how these radio waves are created.

"The FRB is among the closest yet seen, and we even speculated that it could be a more conventional object in the outskirts of our own galaxy," said Mohit Bhardwaj, study co-author and McGill University doctoral student. "However, the observation proved that it's in a relatively nearby galaxy, making it still a puzzling FRB but close enough to now study using many other telescopes."
