In contrast, visible light and longer-wavelength electromagnetic radiation, such as infrared, microwaves, and radio waves, consists of photons with too little energy to cause damaging molecular excitation, and thus this radiation is far less hazardous per unit of energy.
Whatâs keeping this high-energy radiation at bay seems to be neither the Earthâs magnetic field nor long-range radio waves, but rather a phenomenon termed âplasmaspheric hissâ â very low-frequency electromagnetic waves in the Earthâs upper atmosphere that, when played through a speaker, resemble static, or white noise.
