Scientists have discovered a split-second burst of radio waves using the Arecibo radio telescope in Puerto Rico, published July 10 in The Astrophysical Journal.
The finding marks the first time that a “fast radio burst” has been detected using an instrument other than the Parkes radio telescope in Australia.
Scientists using the Parkes Observatory have recorded a handful of such events, but the lack of any similar findings by other facilities had led to speculation that the Australian instrument might have been picking up signals originating from sources on or near Earth.
“Our result is important because it eliminates any doubt that these radio bursts are truly of cosmic origin,” said Victoria Kaspi, an astrophysics professor at McGill University in Montreal and Principal Investigator for the pulsar-survey project that detected this fast radio burst. “The radio waves show every sign of having come from far outside our galaxy — a really exciting prospect.” . . .
