I'm especially confused about this bit: "Typically, when ultra-high-energy cosmic rays hit Earth's atmosphere, they cause a cascade of secondary particles and electromagnetic radiation in what is known as an extensive air shower.

"Typically, when ultra-high-energy cosmic rays hit Earth's atmosphere, they cause a cascade of secondary particles and electromagnetic radiation in what is known as an extensive air shower. Some charged particles in the air shower travel faster than the speed of light, producing a type of electromagnetic radiation that can be detected by specialised instruments."
