The flash was detected by the scientists of Commonwealth Scientific and Industrial Research Organisation (CSIRO) at Parkes radio telescope in Australia.
In Melbourne, Swinburne University of Technology PhD student Emily Petroff 'saw' the burst live - a first for the astronomers. Lasting only milliseconds, the first such radio burst was discovered in 2007 by the astronomers.
Six more bursts, apparently from outside the galaxy, have now been found with the Parkes telescope, in New South Wales, and a seventh with the Arecibo telescope in Puerto Rico.
Astronomers worldwide, have been vying to explain the phenomenon."These bursts were generally discovered weeks, months or even more than a decade after they happened," said Petroff."We are the first to catch one in real time," Petroff said.
