It is a Fast Radio Burst (FRB), it is a transient celestial radio pulse lasting only milliseconds, and thought to be of extra-galactic origin. Yeah you heard me!

There seems to be no real solid theory or explanation, a suggestion is that there could be a connection to gamma ray bursts. They changed rapidly in brightness and so it’s believed that the source must be very small.

It was spotted in 2007, it’s not alone either as four more have been identified since that point. They are very short bursts coming from anything from 5 to 11 billion light years away, so back in time their sounds now come to us to be heard.

We are effectively hearing explosions of the past which sounds pretty awesome to me! Are we hearing events from ancient alien civilisations? Echo’s of events mirroring things like the Big Bang? I’ll leave it up to you to decide.
