Life on Earth depends in part on a thin shell of gaseous ozone that stretches from about 10 to 25 miles above our heads, encompassing the planet like an invisible, protective shield. At this altitude, it lies well above the height at which normal commercial aircraft fly, and far beneath the orbital paths of spacecraft. The ozone layer is the main barrier between us and the hazardous ultraviolet radiation that streams toward the Earth, day in and day out, from the burning surface of the Sun. Ozone--a form of oxygen--is selective in what it takes from sunlight: screening out, through a process of atomic absorption, only the more energetic ultraviolet rays while allowing the visible light and the warm infrared to pass through, untouched
