XVIII Latin American Regional IAU Meeting 2026 (LARIM 2026)

We are pleased to announce and invite you all to the XVIII Latin American Regional IAU Meeting (LARIM 2026), to be held in Cancun, Mexico, from 30 November to 4 December 2026. The meeting will be hosted at the Cancun Center, a modern convention venue located in the hotel zone and approximately 20 minutes from Cancún International Airport.

This is the fourth occasion on which Mexico hosts LARIM, following earlier editions in Mérida, Yucatán (1986), Tonantzintla, Puebla (1998), and Morelia, Michoacán (2010). Located on the Caribbean coast of the Yucatán Peninsula, Cancun provides a setting with a distinctive natural and cultural environment. Nearby archaeological sites bear witness to the astronomical tradition of the ancient Maya, who charted the sky with remarkable precision centuries before the modern era. The surrounding region is also characterized by extensive coral reef systems and networks of cenotes—natural sinkholes formed in limestone—that have long shaped both the local ecosystem and human settlements.
