Arecibo Radio Telescope Confirms Extra-galactic Fast Radio Pulses

schwit1 writes: "The Arecibo radio telescope has confirmed the existence of fast radio pulses. "Fast radio bursts (FRBs) are bright flashes of radio waves that last only a few thousandths of a second. Scientists using the Parkes Observatory in Australia recorded such events for the first time, but the lack of any similar findings by other facilities led to speculation that the Australian instrument might have been picking up signals originating from sources on or near Earth. The discovery at Arecibo is the first detection of a fast radio burst using an instrument other than the Parkes radio telescope. The position of the radio burst is in the direction of the constellation Auriga in the Northern sky.

"Our result is important because it eliminates any doubt that these radio bursts are truly of cosmic origin," continues 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." Exactly what may be causing such radio bursts represents a major new enigma for astrophysicists. Possibilities include a range of exotic astrophysical objects, such as evaporating black holes, mergers of neutron stars, or flares from magnetars — a type of neutron star with extremely powerful magnetic fields." Be warned: All of the above theories could also be wrong. These fast radio flashes could just as easily turn out to be something entirely unpredicted.

    Has anyone tried running these through some pattern recognition algorithms? This could easily be our first contact with a truly extraterrestrial intelligence.

      Being extragalactic, if so they would likely be from a long dead civilization, but yeah. Also that would have to be one hell of an antenna.

      " Just because something happens here on Earth doesn't mean, even in the remotest likelihood, that the rest of the universe operates that way."

      So the periodic table of elements is local? How about electrons and photons? Because if they act differently locally, indeed all observations from far away are suspect.

      For example, analyzing starlight in a spectroscope depends on how we see light behaving here.

      Are you saying you believe it's not certain that it's the same?
