In coordination with the American Astronomical Society (AAS), the Nexus for Exoplanet System Science (NExSS) is pleased to announce the AAS Topical Conference: Habitable Worlds 2021 (HabWorlds2). The goal of the workshop is to identify opportunities and obstacles to cross-disciplinary collaboration on the questions of what makes planets habitable, and life on them detectable. The culminating event will be a synchronous, online conference 22-26 February 2021.

NExSS is a NASA  research coordination network devoted to the study of habitability and detectability of life on exoplanets. In preparation for the meeting in February, NExSS has planned three ice-breaking, community-wide, collaborative online activities 1-31 October 2020, designed to promote interdisciplinary communication and to set the agenda for the conference. These activities will generate input from the fields of astronomy/astrophysics, planetary sciences, and Earth sciences, and are open (after a free signup) to all who wish to participate. The activities are mostly about getting the different communities on the same page, and involve very little time commitment.

For more information on the Conference please see:

To directly sign up for the free Pre-meeting Icebreaker activities please see:

Registration will open by early November.

Your expertise from your discipline is needed to help shape the future study of habitability and detectability of life on exoplanets!
