For the first time, scientists have successfully traced mysterious “fast radio bursts” (FRBs), which have been speculated to be signs of extraterrestrial intelligence, to a galaxy six billion light years away.
Just 17 such radio blasts have been recorded since 2007 when they were first discovered. Each one came from space and lasted a few milliseconds at the most, emitting as much energy as the Sun in about 10,000 years.
Scientists are not sure what causes these bursts. The first step in establishing their origin was to estimate the distance to the object where it originated.
Astronomer Evan Keane from the UK’s Jodrell Bank Observatory, who led the scientific team that published the new findings in the journal Nature, was able to record one of the most recent radio burst called FRB 150418 on April 18, 2015 with the help of the Parkes radio telescope in Australia. It lasted…
