Our central star, the Sun, is magnetically active and is known to drive eruptive events towards Earth: so-called space weather hazards. Many crucial infrastructures, such as satellites, electrical power grids, and communications are vulnerable to these. After more than 50 years of active research, it still remains a mystery how does the Sun drive these eruptive events through magnetic fields generated in its outer convective envelope? We are seeking answers to this question through AI-assisted and GPU accelerated simulation tools run in LUMI-G like top supercomputing infrastructures.
