Earth has received mysterious radio signals from a galaxy 1.5 billion light years away. Researchers spotted 13 radio signal bursts in a three week period.
Cherry Ng, an astronomer at the University of Toronto said: "That could mean in some sort of dense clump like a supernova remnant. Or near the central black hole in a galaxy. But it has to be in some special place to give us all the scattering that we see."
"Whatever the source of these radio waves is, it's interesting to see how wide a range of frequencies it can produce. There are some models where intrinsically the source can't produce anything below a certain frequency," says team member Arun Naidu of McGill University.

Astronomers have revealed details of mysterious signals emanating from a distant galaxy, picked up by a telescope in Canada.
The precise nature and origin of the blasts of radio waves is unknown.
Among the 13 fast radio bursts, known as FRBs, was a very unusual repeating signal, coming from the same source about 1.5 billion light years away.
Such an event has only been reported once before, by a different telescope.
"Knowing that there is another suggests that there could be more out there," said Ingrid Stairs, an astrophysicist from the University of British Columbia (UBC).
"And with more repeaters and more sources available for study, we may be able to understand these cosmic puzzles - where they're from and what causes them."
