Mystery radio waves from deep space captured LIVE, sender unknown

An unknown radio signal, which may have come from a black hole, colliding neutron stars (or – for those who ‘believe’ – alien life), has been picked up by astronomers live for the first time ever. Its origins remain mysterious.

Speculation on the signal's origin

Interstellar scintillation of a weaker continuous signal—similar in effect to atmospheric twinkling—could be an explanation, but that would not exclude the possibility of the signal's being artificial in origin. But even the significantly more sensitive Very Large Array did not detect the signal, and the probability that a signal below the Very Large Array level could be detected by the Big Ear due to interstellar scintillation is low.[6] Other speculations include a rotating lighthouse-like source, a signal sweeping in frequency, or a one-time burst.[4]

Ehman has voiced doubts that the signal was of intelligent extraterrestrial origin: "We should have seen it again when we looked for it 50 times. Something suggests it was an Earth-sourced signal that simply got reflected off a piece of space debris."[9] He later recanted his skepticism somewhat, after further research showed an Earth-borne signal to be very unlikely, given the requirements of a space-borne reflector being bound to certain unrealistic requirements to sufficiently explain the signal.[10] Also, it is problematic to propose that the 1420 MHz signal originated from Earth since this is within the "protected spectrum": a bandwidth reserved for astronomical purposes in which terrestrial transmitters are forbidden to transmit.[11][12] In his most recent writings, Ehman resists "drawing vast conclusions from half-vast data"—acknowledging the possibility that the source may have been military or otherwise a product of Earth-bound humans.

The signal appears to have come from an area of the sky with no stars or planets, northwest of the globular cluster M55.[13] If the source was the size of the largest radio telescope on Earth, it would have required a 2.2-gigawatt (2,200,000 kW) transmitter,[why?] vastly more powerful than any on Earth:[14] the most powerful terrestrial transmitters are the Taldom transmitter at 2500 kW in long wave and the Bolshakovo transmitter at 2500 kW in medium wave.
