Scientists have detected a radio signal from billions of light-years away during their search for aliens.

 

The Breakthrough Listen project launched by Stephen Hawking in 2015 is the biggest search for extraterrestrial life and detected the radio signal while scanning skies from Australia.

 

The Fast Radio Burst, as it’s known, is said to last for a millisecond and sound like an ambulance siren, but according to scientists, ‘aliens are unlikely to be behind the rare and mysterious signal’.
