Hydrogen Clouds from Comets 266/P Christensen and P/2008 Y2 (Gibbs) are Candidates for the Source of the 1977 "WOW" Signal
Antonio Paris, Evan Davies, 2015. Journal of the Washington Academy of Sciences.
Proposes that neutral hydrogen around two comets in the region in 1977 produced the signal. J. Wash. Acad. Sci. 101(4), 25–32. A 2017 follow-up by Paris in the same journal, "Hydrogen Line Observations of Cometary Spectra at 1420 MHz," reported observations of the comets.
What it's used for here
The comet hypothesis, recorded as a reading that has been tested and rejected.
