Has the telescope picked up signals of aliens from another galaxy?

The "fast radio bursts" included one "double signal" never heard before and have left astronomers buzzing with excitement over the possibility of it being a message with alien origins.

Only 11 of the unidentified transient radio pulses have been recorded before around the world.

And it is the curious new double blast - which was accompanied by four "singles" - which has baffled astronomers analysing data from the Parkes radio telescope in New South Wales, Australia.

Emily Petroff from Swinburne University, in Melbourne, one of the team who discovered the signals, believes the origin could be more remarkable than anything recorded before.

She tweeted: "We have no idea what's going on, but we know it's definitely something cool.”
