The Europlanet Science Congress 2025 will be held jointly with the annual meeting of the American Astronomical Society’s Division of Planetary Science (EPSC-DPS2025) from 7–12 September 2025 at Finlandia Hall, Helsinki, Finland. EPSC-DPS2025 covers the full spectrum of planetary research and technology across 74 scientific sessions, with topics including the latest results on Solar System, exoplanetary and interstellar bodies, current and upcoming missions, ground-based observations, the use of artificial intelligence and machine learning in planetary science, planetary defence, and the emergence of life in our Solar System and beyond. Around 1900 oral and poster presentations have been submitted and almost 2000 planetary scientists from Europe and around the world are expected to attend the conference.

Decoding cosmic evolution depends on accurately predicting the complex chemical reactions in the harsh environment of space. Traditional methods for such predictions rely heavily on costly laboratory experiments or expert knowledge, both of which are resource-intensive and limited in scope. Recently, a research team developed an innovative AI tool that predicts astrochemical reactions with high accuracy and efficiency, demonstrating that deep learning techniques can successfully address data limitations in astrochemistry. Titled “A Two-Stage End-to-End Deep Learning Approach for Predicting Astrochemical Reactions,” this research was published May 15 in Intelligent Computing, a Science Partner Journal.

A new study involving more than 700 university students found that trigger warnings do not make students feel more supported or positive toward instructors, despite being widely endorsed. Students who received trigger warnings before trauma-related lectures did not rate instructors as more trustworthy, caring, or open to controversial discussions.In contrast, 'in a safe space' messages had a clear positive impact.

Technicians have successfully installed two sunshields onto NASA’s Nancy Grace Roman Space Telescope’s inner segment. The panels (together called the Lower Instrument Sun Shade), will play a critical role in keeping Roman’s instruments cool and stable as the mission explores the infrared universe.

One bolt of lightning covered a horizontal distance of 515 miles during a 2017 storm. A re-examination of satellite observations revealed the record-setting megaflash.

Kyoto, Japan -- Black holes embody the ultimate abyss. They are the most powerful sources of gravity in the universe, capable of dramatically distorting space and time around them. When disturbed, they begin to "ring" in a distinctive pattern known as quasinormal modes: ripples in space-time that produce detectable gravitational waves.

In events like black hole mergers, these waves can be strong enough to detect from Earth, offering a unique opportunity to measure a black hole's mass and shape. However, precise calculation of these vibrations through theoretical methods has proven a major challenge, particularly for vibrations that are rapidly weakening.

This inspired a team of researchers at Kyoto University to try a new method of calculating the vibrations of black holes. The scientists applied a mathematical technique called the exact Wentzel-Kramers-Brillouin, or exact WKB analysis to carefully trace the behavior of waves from a black hole out into distant space. While this method has long been studied in mathematics, its application to physics -- especially to black holes -- is still a newly developing area.
