Astronomers detect 'mysterious radio burst' from deep space
PHOENIX -- Astronomers have detected a mysterious signal from deep space, raising the question of are we alone?
They are called fast radio bursts and what makes this one different is that it was a much lower frequency range than the others. Scientists still don't know what causes these bursts and they're so far into space that it's difficult for experts to research them.
>>VIDEO: FOX 10's Marc Martinez and Christina Carilla talk to Arizona State University astronomer Nat Butler about what this discovery means.
Butler says once astronomers are able to study these signals routinely, it could only take weeks to figure out what they are and what is causing them.
