Scientists detect a repeating signal from deep space, but its origin is a mystery

To begin, there's zero evidence it's aliens.

But for just the second time, a team of astronomers detected a flash of repeating of radio waves emanating from beyond our Milky Way galaxy. Using a new, sprawling Canadian telescope dubbed CHIME — which is the size of six hockey rinks — scientists identified the short, repeating burst in the summer of 2018 and published their results Wednesday in the journal Nature.  

The source of these super distant signals, from some 1.5 billion light years away, is still largely a mystery. What's agreed upon is that for these radio waves to travel millions of light years and arrive at Earth as strong signals, they must have a profoundly potent origin — perhaps a powerful explosion in another galaxy.  Read more...
