Astronomers using the Hubble Space Telescope tracked four fast radio bursts to the spiral arms of the four distant galaxies. The bursts are catalogued as FRB 190714 (top left), FRB 191001 (top right), FRB 180924 (bottom left) and FRB 190608 (bottom right).

New Hubble Space Telescope observations have given more credence to a theory explaining mysterious radio energy bursts.

The long-running observatory tracked down five fast radio bursts (FRBs) to the spiral arms of five faraway galaxies. FRBs are notoriously hard to trace because the bright flares fade so quickly, and astronomers have only found about 1,000 of them so far, but there are a few theories about their origin stories.

By deduction, the study team discarded older hypotheses associated with FRBs. Because the newly found bursts don't come from regions full of massive stars, this set likely can't be associated with star explosions — such as those that produce supernovas.
