The European Space Agency's Solar Orbiter spacecraft has provided the clearest evidence yet of how solar flares ignite through a cascading magnetic avalanche. Observations from September 30, 2024, reveal small magnetic disturbances rapidly building into powerful explosions that accelerate particles to near-light speeds. This discovery, detailed in a new study, enhances understanding of these solar events and their potential impacts on Earth.
