In 2017, Antonio Paris, Assistant Professor of Astronomy and Astrophysics at St. Petersburg College, Florida,<ref>{{Cite web |title=Prof. Antonio Paris |url=https://web.spcollege.edu/instructors/id/paris.antonio/BIO/ |publisher=St. Petersburg College}}</ref> proposed that the hydrogen cloud surrounding two [[comet]]s, [[266P/Christensen]] and [[335P/Gibbs]], now known to have been in the same region of the sky, could have been the source of the Wow! signal.<ref name="Paris-1">{{Cite journal |last=Paris |first=Antonio |date=January 1, 2016 |title=Hydrogen Clouds from Comets 266/P Christensen and P/2008 Y2 (Gibbs) are Candidates for the Source of the 1977 "WOW" Signal |url=http://planetary-science.org/hydrogen-clouds-from-comets-266p-christensen-and-p2008-y2-gibbs-are-candidates-for-the-source-of-the-1977-wow-signal/ |url-status=dead |journal=Journal of the Washington Academy of Sciences |arxiv=1706.04642 |bibcode=2017arXiv170604642P |archive-url=https://web.archive.org/web/20170615182709/http://planetary-science.org/hydrogen-clouds-from-comets-266p-christensen-and-p2008-y2-gibbs-are-candidates-for-the-source-of-the-1977-wow-signal/ |archive-date=June 15, 2017 |access-date=June 13, 2017}}</ref><ref name="Paris-2">{{Cite journal |last=Paris |first=Antonio |date=1 April 2017 |title=Hydrogen Line Observations of Cometary Spectra at 1420 MHZ |url=http://planetary-science.org/research/the-wow-signal/ |url-status=dead |journal=Journal of the Washington Academy of Sciences |volume=103 |issue=2 |archive-url=https://web.archive.org/web/20220509154206/http://planetary-science.org/research/the-wow-signal/ |archive-date=May 9, 2022 |access-date=13 June 2017}}</ref><ref>{{Cite arXiv |eprint=1706.04642 |class=astro-ph.EP |first1=Antonio |last1=Paris |first2=Evan |last2=Davies |title=Hydrogen Clouds from Comets 266P Christensen and P2008 Y2 (Gibbs) are Candidates for the Source of the 1977 WOW!Signal |year=2017}}</ref> This hypothesis was dismissed by astronomers, including members of the original Big Ear research team, as the cited comets were not in the beam at the correct time. Furthermore, comets do not emit strongly at the frequencies involved, and there is no explanation for why a comet would be observed in one beam but not in the other.<ref name="NAAPO-1">{{Cite web |last=Dixon |first=Robert S. |title=Rebuttal of the claim that the "WOW!" signal was caused by a comet |url=http://naapo.org/WOWCometRebuttal.html |access-date=June 13, 2017 |website=NAAPO |publisher=North American Astrophysical Observatory}}</ref><ref name="NS-1">{{Cite magazine |last=Emspak |first=Jesse |date=11 January 2016 |title=Famous Wow! signal might have been from comets, not aliens |url=https://www.newscientist.com/article/dn28747-famous-wow-signal-might-have-been-from-comets-not-aliens/ |access-date=13 June 2017 |magazine=[[New Scientist]]}}</ref><ref>{{Cite news |last=Mack |first=Eric |date=14 June 2017 |title=Aliens could still explain the 'Wow signal,' scientists say |url=https://www.cnet.com/news/aliens-wow-signal-comets-antonio-paris-seti/ |access-date=2021-05-31 |publisher=CNET}}</ref>
