In this video from NOVA’s Sun Lab, examine how scientists use electromagnetic radiation to learn about the Sun. The process of nuclear fusion in the core of the Sun produces energy in the form of electromagnetic radiation, or light. The wavelength of photons (particles that carry electromagnetic energy) depends on how much energy the photons carry. The Sun emits energy at a range of wavelengths; however, until recently, human observations of the Sun were limited to the narrow visible range. Advances in technology have allowed humans to make observations across the electromagnetic spectrum that have revealed the dynamic nature of the Sun.
