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.

A talk with scientists across Europe: building the future of European heliophysics together
“Heliophysics studies the Sun, its sphere of influence, and how it affects the bodies in the solar system.” – this holistic approach to understanding our space environment is at the heart of the European Heliophysics Community (EHC), an open and inclusive network of researchers across Europe (https://www.heliophysics.eu/). The EHC promotes collaborative, curiosity-driven science that explores the plasma processes shaping our heliosphere, planetary magnetospheres, and ionospheres. But what does heliophysics mean to the people driving this science forward, and why is …

ST-ECS Networking Campfire: “How to Navigate Between Academia and Industry”
For many early-career scientists, one of the big questions is whether to pursue a career in academia, move into industry, or find a path that bridges both worlds. Each sector offers unique opportunities and challenges, and learning how to navigate between them can help you make confident, informed career decisions. To shed light on this topic, the Early Career Scientists (ECS) team of the Solar-Terrestrial (ST) division of the European Geosciences Union (EGU) is organizing a Campfire Event featuring Dr. …

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 …

Current issue of the EGU newsletter
In our October Issue we are feeling the spooky season as we talk with Elizabeth Case, a 'hauntologist' who studies the ghosts of glaciers, Asmae Ourkiya investigates a recent study of the shadows left behind on the climate from a massive eruption in Indonesia, we hear from Peter Alexander, who shares his experience of doing research in an autocratic regime in the Global South, we share all the upcoming webinars planned for November (there are a lot!), and don't miss our announcement of a new Emergency Support policy, to help researchers in the Earth, planetary and space sciences who have been affected by disaster, crisis or conflict.
All this and much more, in this month's Loupe!
