Severe space weather events pose risks to global infrastructure, including satellite operations, power grids, and communication networks. A 2025 estimate by Lloyds suggested that a major event could cost the global economy $2.4 trillion over five years. Astronauts are also directly affected, experiencing bright flashes of light due to high-energy particles penetrating spacecraft and their bodies. The potential for widespread disruption underscores the importance of monitoring and preparedness.
