When the Sun Blasted Earth with High-Energy Light and Subatomic Particles
In 774 AD, the sun changed our atmospheric chemistry.

The common factor in all these elements is that they are created when extremely high-energy subatomic particles hit Earth’s air and ground. They slam into the nuclei of atoms and change them, creating these isotopes. The only way to get particles at energies like this is from space, where powerful magnetic fields in exploding stars, for example, can accelerate the particles to such high speeds. We call these isotopes cosmogenic, made from space.
