2025 Sagan Summer Workshop. Silver Jubilee: Exoplanet Demographics
21-25 July 2025
The topic of the 2025 Sagan Summer Workshop will be the “Demographics of Exoplanets” and will address the contribution of each of the major planet-finding techniques to our overall knowledge of the architecture of exoplanet systems. Along with presentations about each technique and its particular strengths and biases, the workshop will address the synthesis of these results into a complete demographic picture for comparison with models of the formation and evolution of planetary systems. The Workshop will explore gaps in our knowledge and how future missions and surveys will address them. Of particular interest will be understanding the importance of a full demographic picture, including the incidence of Earth-sized planets in the Habitable Zones of their host stars, to future missions such as the Habitable Worlds Observatory.

EPSC-DPS—EXOA13: Bridging geosciences and astronomy to interpret rocky (exo)planet observations. Finland Hall, Finland, 7-12 September 2025
The coming years will be revolutionary for rocky planet research, with JWST, ELT, ARIEL, and PLATO providing unprecedented observations of rocky exoplanets in our galaxy. At the same time, BepiColombo, the Mars sample return mission, and the Decade of Venus missions will greatly enhance our understanding of the rocky bodies within the Solar System. These missions will offer valuable new observations of the atmospheres and surfaces of these rocky bodies, while Solar System missions will also probe magnetic fields. Interpreting these observations, and leveraging them to constrain the body’s interior properties, requires a deeper understanding of how a planet’s surface, atmosphere, and interior interact.

EPSC-DPS—EXOA18: Investigating Habitability and Biosignatures within Exoplanet Atmospheres. Finland, 7-12 September 2025
JWST has enabled researchers across the globe to probe the atmospheric composition of exoplanets and investigate the properties of distant planetary systems. Future confirmed and conceptual campaigns such as the ELT, HWO and LIFE aim to pay greater attention to Earth-mass planets orbiting within the habitable zones of their host stars. In anticipation of these missions, this session focuses on the current and future search for biosignatures within the atmospheres of exoplanets, the identification of habitable worlds and the exploration of planetary conditions that support habitability. It solicits contributions from both observers using data collected by past and present instrumentation, as well as atmospheric, stellar activity, and interior modellers looking towards future observations. The session aims to foster new collaborations with observers, modellers, and instrument team members to assess how markers of life and habitability in distant systems may present themselves to us, and the requirements that future observing campaigns need to reliably identify them within planetary parameter space.

International Conference on Exoplanets and Planet Formation (EPF) , Shanghai, China, December 8-12, 2025

This event will cover all aspects of exoplanetary astrophysics, including: Exoplanet detection and characterization (mass-radius relations, atmospheres, demographics and statistics, etc), Planet formation and dynamical evolution, Related topics such as star formation, binaries and multiples, and Solar System formation.

Rocky Worlds 4, 19–23 January 2026, Groningen, Netherlands
The planets that are best understood are the four terrestrial planets of our own solar system. Applying the detailed understanding gleaned from these bodies is crucial in our interpretation of exoplanetary systems. With the ongoing programs to search for planets around nearby stars, as well as upcoming ground- and space-based surveys, we can anticipate huge growth in the number and information on detected rocky exoplanets in the coming decades. As the characterisation of these new planetary systems proceeds it will in turn improve understanding of our own solar system, and in particular of how potentially habitable Earth-like planets may form, evolve, and are distributed throughout the galaxy.
