Mystery repeating energy bursts in deep space 'could be aliens'

Theories include a neutron star that has a strong magnetic field spinning rapidly, the merging of two neutron stars and even alien spaceships. Knowing that there is another suggests that there could be more out there.

Canadian astronomers have reportedly discovered a repetitive radio signal some 2.5 billion light-years away from Earth - only the second example known to mankind. A repeating FRB, however, provides more opportunities for scientists to learn about these radio bursts and where they come from.

"Their origin is still unknown", said the University of British Columbia astronomer Deborah Good, one of the co-authors of two papers about the detections published today by the journal Nature. The first FRB was recorded in 2001 and identified in 2007, while the first repeating FRB was detected in 2012.

'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'.

Before CHIME began to gather data, some scientists wondered if the range of radio frequencies the telescope had been created to detect would be too low to pick up fast radio bursts.

Mysterious energy readings from deep space that some experts have suggested could be evidence of alien life have been detected for only the second time.

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

Researchers at the University of British Columbia in Canada said they've discovered the second so-called "repeating fast radio burst" (FRB) ever recorded, according to a news release published January 9. "We haven't solved the problem, but it's several more pieces in the puzzle". "Our data will break open some of the mysteries of FRBs".

The team - who have been specifically looking for FRBs - also noted that all of the new signals observed have been under 800 MHz, which is much lower than the previously detected frequencies, which hovered around the 1,400 MHz area.

At distances of billions of light years it's obviously very hard to test any of these theories, but detecting more FRBs, especially those that have a habit of repeating, could bring us closer to an explanation.

"[We now know] the sources can produce low-frequency radio waves and those low-frequency waves can escape their environment, and are not too scattered to be detected by the time they reach the Earth", he said.

Team member Dr Cherry Ng, from the University of Toronto, Canada, said: 'That could mean in some sort of dense clump like a supernova (exploding star) remnant.

A majority of the intercepted fast radio bursts shows signs of "scattering", a phenomenon that reveals information about the environment where the radio waves originated from, Phys.org reported.
