Phenomena observable from Earth, visually manifesting as luminescence in the atmosphere, encompass a wide range of optical effects. These occurrences can be generated by natural processes, such as electromagnetic radiation interacting with atmospheric gases, or by artificial sources. Examples include auroras, meteor showers, and nocturnal illumination from human settlements.
The study and observation of these occurrences provide valuable insights into atmospheric conditions, space weather, and even the impact of human activity on the environment. Historically, these visual displays have held cultural and spiritual significance, often interpreted as omens or manifestations of the divine. Modern scientific investigation allows for a more precise understanding of the physics and chemistry behind these celestial displays.
