Mysterious radio signal from space stumps scientists
Scientists have been left mystified by a radio signal sent from outer space.
The “fast radio burst” came from outside our own galaxy – but experts have no idea what caused it.
Radio burst FRB 150215 was received on February 15, 2015 by the Parkes Telescope in Australia.
It is the 22nd cosmic signal of its kind.
But after two years, the experts are no closer to finding out exactly what it was – or where it came from.
Harvard researchers have suggested that these fast radio bursts (FRB) are caused by alien space travel or advanced alien technology.
But according to a recent study published by Cornell University, scientists are no closer to settling the debate.
“The burst was followed-up with 11 telescopes to search for radio, optical, X-ray, gamma-ray and neutrino emission.
“Neither transient nor variable emission was found to be associated with the burst and no repeat pulses have been observed in 17.25 hours of observing,” writes astronomer Emily Patroff in a study published by Cornell University.
To put it simply, the signal discovery is the equivalent of hearing a loud bang and then turning around and finding nothing.
