Exclusive: We Might Have First-Ever Detection of a Fast Radio Burst in Our Own Galaxy
A Milky Way magnetar called SGR 1935+2154 may have just massively contributed to solving the mystery of powerful deep-space radio signals that have vexed astronomers for years.

Some background history to this. The SETI at home results threw up a handful (between 5 and 10) of mysterious powerful narrowband radio bursts way outside the statistical envelope of background events. These were all single transient events.
At the time, these were written off as atmospheric scintillation of powerful steady state radio signals, but I’ve never been convinced of that, mostly because the existence of these steady state radio sources remained purely hypothetical and not confirmed by follow up studies. LGM (eg. spacecraft communication) seemed a more plausible explanation.
But just perhaps SETI had stumbled upon magnetar bursts within our own galaxy. These would be rare enough and powerful enough to show up above the statistical background.
