The EPSC-DPS 2025 Joint Meeting, a collaboration between the Europlanet Science Congress (EPSC) and the American Astronomical Society’s Division for Planetary Sciences (DPS), will take place from 7–12 September 2025 at Finlandia Hall in Helsinki, Finland. This marks the 57th Annual DPS Meeting and brings together planetary scientists, mission specialists, and students from around the world to share the latest research and developments in planetary science.
The conference will feature a diverse program including oral and poster sessions, workshops, and panel discussions. Topics will span a wide range of planetary science disciplines, such as planetary atmospheres, surface processes, small bodies, exoplanets, and astrobiology. Special emphasis is placed on early-career participation, public outreach, and diversity in science.
The local organizing committee is chaired by Maria Genzer, with the scientific organizing committee co-chaired by Ákos Kereszturi, Stavro Ivanovski, and Conor A. Nixon. The venue, Finlandia Hall, offers a central and scenic location for this major international event, highlighting Finland’s growing role in space research and planetary missions.
Taurus Hill Observatory will present its research work in the EPSC-DPS on Monday 8.9. and Tuesday 9.9. The short abstracts of both presentations are below.
Exoplanet Observations from Taurus Hill Observatory for the Season 2024–2025
Taurus Hill Observatory (THO), conducted exoplanet transit observations during the 2024–2025 season despite challenging weather conditions. The season began with the first successful transit measurement of TOI-6034.01b, showing a slightly shorter and shallower transit than expected. Additional targets observed included TOI-1845.01b, TOI-2578.01b, TOI-1259.01b, and HAT-P-36b, with results generally aligning with expected values.
The observatory used a Celestron C-14 SC telescope with an SBIG ST-8XME CCD camera and photometric filters. A new ASI2600MM Pro CMOS camera was tested and proved suitable for light curve measurements, leading to its adoption for future observations.
Comet 17P/Holmes: Modeling Its 2007 Outburst
Markku Nissinen and collaborators presented a study on the 2007 outburst of Comet 17P/Holmes, one of the most dramatic cometary events observed in recent decades. The team developed a model to simulate the sublimation of volatile materials and the dust propagation that followed the sudden brightening. Their approach combines observational data with physical modeling to better understand the mechanisms behind such explosive activity. The results help clarify how internal pressures and thermal processes can lead to large-scale dust ejection, offering insights into comet evolution and behavior.
