# 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.
