Explore the fascinating science of auroral currents in this 28-minute lecture presented by Dr. Ramón López. Delve into the physics of auroral phenomena, starting with an overview of magnetic fields and their relationship to electric currents. Discover how the Sun's magnetic field interacts with Earth's magnetosphere to create the breathtaking auroral displays. Examine the historical context of auroral research, from early compass navigation to modern space missions like NASA's THEMIS. Learn about field-aligned currents, their role in producing auroras, and how similar phenomena occur on other planets. Investigate the potential impacts of severe geomagnetic storms on Earth's technology and infrastructure. Gain insights into the ongoing scientific efforts to understand the energy flow powering auroras and auroral currents.
