The Division on Solar-Terrestrial Sciences (ST) considers all aspects of solar and heliospheric physics, specifically the solar-terrestrial connection. It covers the physical processes occurring on the Sun, in the solar wind, as well as in Earth's magnetosphere and ionosphere. Solar activity (e.g. coronal mass ejections, solar flares, solar energetic particle events) and the response of the near-Earth space environment to these solar phenomena are studied on a wide-range of temporal and spatial scales. Data analysis and interpretation of space-borne and ground-based data, as well as theoretical studies and different modelling techniques are used to better our understanding of how our local star defines the neighbourhood that we live in.

Chasing Auroras 41 Millennia Ago with Agnit Mukhopadhyay and Sanja Panovska
Approximately 41,000 years ago, during the Laschamps geomagnetic excursion, Earth’s magnetic field experienced a significant disturbance. The strength of the magnetic field decreased to only 10% of what it is today, the magnetic poles shifted considerably from the geographic poles, and the magnetosphere—the protective layer surrounding our planet—became smaller and distorted in previously unvisualized ways. For the first time, a recent study by Agnit Mukhopadhyay, Sanja Panovska, and colleagues (2025) has reconstructed the global space environment during this period, revealing …

A Week to Remember: My EGU 2025 Experience
Vienna transformed into a buzzing hub of scientific exchange as the European Geosciences Union (EGU) General Assembly (GA) 2025 took place from 27 April to 2 May. Over 20,000 scientists from 120 countries gathered to share groundbreaking research across the Earth, planetary, and space sciences. Attending the GA for the first time as part of the Early Career Scientists (ECS) Team of the Solar-Terrestrial Sciences (ST) Division was inspiring and eye-opening. Here are some of my impressions from this exciting …
