That Blast of Radio Waves Produced By Colliding Dead Stars? Not So Fast.
Sometimes science happens quickly. Over the weekend, follow-up observations of a faraway galaxy challenged the conclusions of a study published just last week, which was reported with much fanfare by news outlets that didn’t dig deeply enough to uncover already existing skepticism about the results.
On Feb. 24, astronomers reported in Natureastronomers reported in Nature that a hugely energetic blast of radio waves originated in a galaxy about 6 billion light-years away. These blasts of radio waves, called fast radio bursts (FRBs), have puzzled scientists since the first one was discovered in 2007.
For nearly a decade, one of the major goals in understanding FRBs has been finding a burst’s host galaxy—with that information in hand,
