Arecibo detects repeated fast radio burts (FRBs) for first time. Source is enigmatic.

The findings indicate that these “fast radio bursts” come from an extremely powerful object which occasionally produces multiple bursts in under a minute.

It's probably a broadcast of Hitler opening the 1936 Olympic Games

Without reading the link provided.... my 1st thoughts were ' Gamma Ray Bursts.'

They are 1 of the most powerful ' events ' in the Universe. and only last a second or so.

Still a mystery but a neutron star in another galaxy is one consideration.
A couple of key paragraphs from the press release -

That paper suggested FRBs are related to cataclysmic events, such as short gamma-ray bursts, which can not generate repeat events. “However, the apparent conflict between the studies could be resolved, if it turns out that there are at least two kinds of FRB sources”, notes McGill physics professor Victoria Kaspi, a senior member of the international team that conducted the Arecibo study.

My first thoughts when I started reading the press release a day or two ago were star quakes on a neutron star. They are repeatable (no idea on time scale) and are a release of built up energy within the dense object.
