![]() ![]() The results of this investigation, therefore, conclude that cometary spectra are detectable at 1420 MHz and, more importantly, that the 1977 “Wow” Signal was natural phenomena from a Solar System body. During observations of these comets, we detected a radio signal at 1420 MHz. Furthermore, to determine if comets other than 266/P Christensen emit a radio signal at 1420 MHz, we observed three comets that were selected randomly from the JPL Small Bodies database: P/2013 EW90 (Tenagra), P/2016 J1-A (PANSTARRS) and, 237P/LINEAR. Casually listening out into the dark mysteries of space, he was looking after the Big Ear telescope at Ohio State University. When the radio telescope was repositioned back to 266/P Christensen, a radio signal at 1420.25 MHz re-appeared. The bored, tired scientist listening out for the glimmer of contact originating from the deepest and darkest unexplored space. During this experiment, the 1420.25 MHz signal from the comet disappeared. In an effort to dismiss the source of the signal as emitting from 266/P Christensen, the position of the 10-meter radio telescope was moved 1° (60 arcminutes) away from comet 266/P Christensen. During observations of the comet, a series of experiments determined that known celestial sources at 1420 MHz (i.e., pulsars and/or active galactic nuclei) were not within 15° of 266/P Christensen. All radio emissions detected were within 1° (60 arcminutes) of the known celestial coordinates of the comet as it transited the neighborhood of the “Wow!” signal. The investigation discovered comet 266/P Christensen emitted a radio signal at 1420.25 MHz. Using the notation of Uscin< l.i ( 1977) and adapted from Fallows (200 I). From 27 November 2016 to 24 February 2017, the Center for Planetary Science conducted 200 observations in the radio spectrum to validate the hypothesis. wind through scintillation in the radio signal received from distant. It was August 15, 1977, when astronomer Jerry Ehman was examining data coming from Ohio State University's radio telescope, which was engaged in listening for signals from deep space, hoping to find something of intelligent origin. Abstract In 2016, the Center for Planetary Science proposed a hypothesis arguing a comet and/or its hydrogen cloud were a strong candidate for the source of the “Wow!” signal. ![]()
