Researchers for the first time have tracked a pulsing radio signal in space back to its original source — deep in our Milky Way galaxy. The team, led by Natasha Hurley-Walker, has learned that at least one of the mysterious radio signals to reach Earth — they have puzzled scientists for half a century — originated from a red dwarf star.

Scientists have been puzzled for years about the source of mysterious radio bursts, but they may now finally have an answer. The repeating bursts of radio waves, which were discovered in 2022, have been a source of intrigue ever since they were discovered.
