Call for Abstracts: AOGS 2026 solar system-exoplanet session

Dear Colleagues,

A session of the AOGS 2026 meeting (PS01 https://www.asiaoceania.org/aogs2026/public.asp?page=sessions_and_conveners.asp) entitled “Worlds Without End” will be held in Fukuoka, Japan. The aim of the session is to bridge the solar system and exoplanet sciences. Visit the AOGS conference website https://www.asiaoceania.org/aogs2026/public.asp?page=home.asp for abstract submissions if you are interested. The deadline for submissions is Jan 23, 2026. Below is the session information.

Worlds Without End: Characterizing the Environments of Planets and Satellites in the Solar System and Beyond

Rocky planets and icy satellites across the Solar System provide critical case studies for understanding the origins and limits of habitability. From subsurface oceans and transient atmospheres to ancient river valleys and volcanic worlds, these diverse environments illustrate the processes that govern volatile evolution, climate stability, and orbital dynamics between planets, satellites, and host stars. At the same time, the discovery of thousands of exoplanets has expanded our view of planetary diversity, underscoring the need to interpret distant worlds through the lens of nearby analogs.

This session invites interdisciplinary contributions that explore the geophysical and astrophysical conditions of planets and satellites both within and beyond the Solar System. We welcome studies drawing on spacecraft missions, laboratory experiments, field analogs, and theoretical or numerical models. Topics may include volatile delivery and loss, dynamical interactions among planets, satellites, and their hosts, atmospheric and surface evolution, photochemistry and climate processes, geophysical activity, planetary spectra, or any related perspective that connects Solar System exploration with the broader context of exoplanets. By fostering dialogue across communities, this session seeks to highlight the shared frameworks that guide the search for habitable worlds, and the potential for life, throughout the cosmos.
