Helen uses eyewitness footage of eruptions, new thermal imagery and high-speed photography to understand the complex processes captured on camera when volcanoes erupt.
Helen examines the hottest natural phenomenon on Earth - lightning. She explains how specialist photography is revealing how lightning travels through the air and high-speed cameras are showing upward lightning.
Helen looks into some of the latest scientific insights into the aurora, from networks of cameras capturing its vast scale to experiments that test the threat that it poses to modern technology.
