A brief mysterious pulse recently detected by an Arecibo telescope has baffled scientists, UK MailOnline reported. But was it a message from far beyond our own galaxy?

The discovery has raised major new questions by scientists using the Arecibo radio telescope in Puerto Rico over what caused a split-second burst of radio waves. It marks the first time that a so-called “fast radio burst” has been detected using an instrument other than the Parkes radio telescope in Australia, stated the findings by an international team of astronomers, and published July 10 in The Astrophysical Journal. “The brightness and duration of this event, and the inferred rate at which these bursts occur, are all consistent with the properties of the bursts previously detected by the Parkes telescope in Australia,” said Laura Spitler, lead author of the new paper.

The unusual pulse was detected on Nov. 2, 2012, at the Arecibo Observatory, a National Science Foundation-sponsored facility that boasts the world’s largest and most sensitive radio telescope, with a radio-mirror dish spanning 305 meters and covering about 20 acres.

Although a handful of such events have been recorded by scientists using the Parkes Observatory, the lack of any similar findings by other facilities has 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.”
