Then, in 1859 , while watching sunspots,a British astronomer saw a sudden , brief flare of sunlight. Enormous,spectacular auroras were observed from earth shortly thereafter, extending all the way to Puerto Rico. The link between the northern lights and the sun was definitively established.
Sydney Chapman finally offered a viable theory about that link in 1918. His idea , the E = mc2 of its field , revolutionized understanding of the phenomenon. It was used by others to create the theory that survives to this day: Plasma, a soup of ions and electrons,shoots from the sun in a solar wind . This ghostly breeze disturbs Earth's magnetic field and prompts air molecules to emit colored lights - the transient but glorious aurora borealis.
