Gamma-Ray Earth and Sky

COSMIC MESSAGE
From Earth orbit, our planet is the brightest source of gamma-rays for telescopes like Fermi's Large Area Telescope. These gamma-rays are produced when high-energy cosmic rays from space collide with Earth's atmosphere. This interaction blocks harmful radiation from reaching the surface, but it creates a bright gamma-ray glow around the Earth.
