Aliens could be behind mysterious radio waves from deep space

New series of fast radio burst from deep space detected

There's one near-certainty: these bursts are likely to be much more common. "Fast Radio Burst" or FRBs signals are not uncommon.

Far outside our Milky Way galaxy, something is causing repeating short bursts of radio waves to be released into space.

Though scientists don't yet have an explanation for fast radio bursts, the latest signals reveal significant levels of "scattering" - details that could help scientists better characterize the nature of the astrophysical environs from which they originate.

The only other detected repeating FRB signal was picked up in November 2012.

This sudden influx of tantalising clues has made astrophysicists nearly giddy. "Instead it uses digital signal processing to "point" the telescope and reconstruct where the radio waves are coming from", says Masui.

Work on the Canadian Hydrogen Intensity Mapping Experiment (CHIME), which Tendulkar and his colleagues used for their research, was not quite complete when this initial baker's dozen was detected last July and August.

CHIME scans the entire Northern Hemisphere every day, hopping from one spot to the next every 15 minutes.

CHIME has been fully operational since September.

This breakthrough is now for the second where the scientists are observing such a radio blast again. "There are some models where intrinsically the source can't produce anything below a certain frequency", team member Arun Naidu of McGill University said in a statement.

I think we're all secretly hoping it's aliens, and some experts think that's worth considering.

But, from whatever little data exists, most scientists do not believe that FRBs are attempts by aliens to contact us. The fact that seven of the new bursts registered at 400 MHz (the lowest frequency the CHIME telescope is able to detect) suggest that FRBs with even lower frequencies are likely zipping past our planet all the time - we just aren't able to see them yet.

Astronomers in Canada have detected a mysterious volley of radio waves from far outside our galaxy, according to two studies published Wednesday in Nature.

A team of Canadian scientists - including several from B.C. - has recorded only the second ever repeating radio burst from outside our galaxy. "We still have a sample size of only two". Some have suggested that it may be remnants of distant supernovae (exploding stars) or radiation emitted by supermassive black holes feeding on them. The scientists note that until now, there was only one known repeating FRB. It also heard a very unusual repeating signal, coming from the same source about 1.5 billion light years away. Even though we thought that the Sun is powerful, one of those bursts owns 25 million times more energy than the big star.

But, as it stands, all of these answers stem from the realm of possibility.

There's no definitive cause of these fast radio bursts and it's unclear what caused multiple FRBs from the same location.
