Aristotle, Seneca, Descartes, Tycho Brahe, and Benjamin Franklin tried to discover all the secrets of the Northern lights.
Italian astronomer, physicist, engineer and philosopher Galileo Galilei had, as you know, a lot of talent. He was called the father of science, father of modern physics, and he greatly influenced the scientific world of the Renaissance.
