Ilya G. Usoskin: Advancing Space Climate and Cosmic Ray Research
In the vast study of our solar system, understanding the long-term behavior of the Sun and its interaction with the Earth is critical for protecting modern technology. Ilya G. Usoskin is a prominent researcher dedicated to this field, specializing in space climate—the study of the Sun's variability over decades, centuries, and millennia.
Based at the University of Oulu in Finland, Usoskin's work bridges the gap between astrophysics and geophysics, utilizing cosmic ray data to reconstruct the history of solar activity. His research provides essential insights into how the Sun's magnetic environment evolves and how these changes impact the terrestrial environment.
