Hydrogen Line Observations of Cometary Spectra at 1420 Mhz

TL;DR

This study conducted radio observations of a comet and found that cometary hydrogen emissions at 1420 MHz can produce signals similar to the Wow! Signal, suggesting a natural Solar System origin.

Contribution

It provides empirical evidence that cometary hydrogen clouds emit detectable signals at 1420 MHz, supporting a natural explanation for the Wow! Signal.

Findings

Detected radio emission from comet 266/P Christensen at 1420.25 MHz

Confirmed cometary spectra are observable at 1420 MHz

Supported the hypothesis that the Wow! Signal was a natural Solar System phenomenon

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. From 27 November 2016 to 24 February 2017, the Center for Planetary Science conducted 200 observations in the radio spectrum to validate the hypothesis. The investigation discovered that comet 266/P Christensen emitted a radio signal at 1420.25 MHz. The results of this investigation, therefore, conclude that cometary spectra are detectable at 1420 MHz and, more importantly, that the 1977 Wow! Signal was a natural phenomenon from a Solar System body.
