'''Eden Patera''' is a feature located in the [[Mare Acidalium quadrangle]] on the planet [[Mars]]. In October 2013 the feature gained some attention when it was speculated it may be a [[supervolcano]] rather than an [[impact crater]], according to research from the [[Planetary Science Institute]] in [[Tucson]], led by Joseph R. Michalski.<ref>[https://www.astronomy.com/news/2013/10/mars-crater-may-actually-be-ancient-supervolcano Mars crater may actually be ancient supervolcano], astronomy.com</ref><ref>[http://www.nasa.gov/content/goddard/mars-crater-may-actually-be-ancient-supervolcano/index.html#.UmcSrco8v2k Mars Crater May Actually Be Ancient Supervolcano] {{Webarchive|url=https://web.archive.org/web/20211214004736/http://www.nasa.gov/content/goddard/mars-crater-may-actually-be-ancient-supervolcano/index.html#.UmcSrco8v2k |date=2021-12-14 }}, NASA, Oct. 22, 2013</ref><ref name="auto">{{Cite journal|title=Supervolcanoes within an ancient volcanic province in Arabia Terra, Mars|first1=Joseph R.|last1=Michalski|first2=Jacob E.|last2=Bleacher|date=October 7, 2013|journal=Nature|volume=502|issue=7469|pages=47–52|doi=10.1038/nature12482|pmid=24091975|hdl=2060/20140011237|hdl-access=free}}</ref> The research postulated the crater was formed by the volcano's [[caldera]] collapsing, rather than from an impact.<ref name=Amos-2017-02-12>{{Cite news|url=https://www.bbc.com/news/science-environment-24348673|title=Supervolcanoes ripped up early Mars|last=Amos|first=Jonathan|date=2013-10-02|newspaper=BBC News|access-date=2017-02-12|language=en-GB}}</ref> Some of the reasons for suspecting that Eden Patera is a collapsed caldera rather than an impact crater are its irregular shape, an apparent lack of a raised rim or central peak, and lack of impact [[ejecta]].<ref name=Amos-2017-02-12/>
