Now this could be interesting

The Chinese have the largest radio telescope in the world. They heard something. From Xinhua:

China's giant telescope picks up mysterious signals from deep space
Chinese astronomers have detected repeated fast radio bursts (FRB) - mysterious signals believed to be from a source about 3 billion light years from Earth - with the largest and most sensitive radio telescope ever built.

Scientists detected the signals with the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) and they are carefully cross-checking and processing them, according to researchers at the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC).

FRBs are the brightest bursts known in the universe. They are called "fast" because these blips are very short, only several milliseconds in duration. But there is no reasonable explanation for their origin.

Might be just a leak from the break-room microwave oven but you never can tell. Things might get interesting...

Here is a blurb about the building of the scope and here is the English website for FAST
