A mysterious new discovery coming from a galaxy 1.5 billion lightyears away has reignited the search for extra-terrestrial life.
Blasts of repeated radio signals have been detected by scientists originating from deep space for only the second time.
These kind of radio bursts have been linked to a number of theories – from exploding stars to alien transmissions. Though scientists have struggled to find any evidence to pin-point the origin.
The flashes only last for a milisecond but they are flung out with the same amount of energy the sun takes 12 months to produce.
The most exciting of the new bursts is one that scientists saw repeat six times, reportedly from the same location. Of the more than 60 fast radio bursts detected so far, only one of them has ever repeated.
“Until now, there was only one known repeating FRB. Knowing that there is another suggests that there could be more out there. 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,” said Ingrid Stairs, a member of the CHIME team and an astrophysicist at UBC.
Having two sets of repeating bursts could now allow scientists understand what separates them from single bursts, helping them understand more about their source and monitor future blasts.
“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.
This discovery comes just over a day after a new ‘super Earth’ was discovered, a new planet that could potentially contain life.
K2-288Bb, is said to be roughly twice the size of earth and is particularly exciting astronomers as it is located within its star’s habitable zone.
ocated 226 light-years away int he constellation Taurus, the new planet could be rocky or a gas-rich planet similar to Neptune according to NASA.
