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.

Don’t Miss the EGU-ST Early-Career Scientist Events during EGU26!
As the EGU General Assembly (GA) 2026 approaches, Solar-Terrestrial (ST) Division Early-Career Scientist (ECS) team organized various events to give researchers a platform to network with their peers, and strengthen our community! What is ECS? Students (BSc, MSc), PhD candidates and researchers who obtained their highest academic degree in the last seven years are Early-Career Scientists as EGU guidelines indicates. We welcome all ECS to our informal events during the general assembly! You can also find these events on the …

ST-ECS Networking Campfire: “How to Mentor”
In academia, success is often measured with quantifiable outputs such as publications, grants, and awards. On the other hand, the challenging road leading to this success is not something discussed openly. The relationship we build with our colleagues, the support and guidance we receive from mentors and supervisors are important factors affecting our success as individuals and as a community. Mentors play a crucial role in this guidance through constructive feedback, encouragement, or sometimes just being there to listen. Support …
