Scientists have spotted repeated blasts of radio signals coming from deep in space.
The breakthrough is only the second time scientists have seen such a repeating radio burst.
It both deepens the mystery and offers a potential opportunity to finally understand what might be throwing out the burst from a galaxy billions of light years away.
Of the more than 60 fast radio bursts detected so far, only one of them has ever repeated.
“Until now, there was only one known repeating FRB. Knowing that there is another suggests that there could be more out there. And with more repeaters and more sources available for study, we may be able to understand these cosmic puzzles-where they’re from and what causes them,” said Ingrid Stairs, a member of the CHIME team and an astrophysicist at UBC. Seeing two repeating signals probably means that there exists – and that humanity will probably find – a “Substantial population” of repeating signals, the researchers write in one of the two papers published in Nature.
Having two sets of repeating bursts could also allow scientists to understand what distinguishes them from single bursts, helping them understand more about their source and watch for future blasts.
Some scientists had worried that the range of frequencies it can pick up would be too low for it to receive the FRBs – but it found far more than expected, and scientists expect it to identify even more.
