12Background (astronomy) — In astronomy, background commonly refers to the incoming light from an apparently empty part of the night sky. Even if no visible astronomical objects are present in given part of the sky, there always is some low luminosity present, due mostly… …
13Infrared signature — The term infrared signature is used by defense scientists and the military to describe the appearance of objects to infrared sensors. An infrared signature depends on many factors, including the shape and size of the object, temperature and… …
14Infrared sensing in snakes — The ability to sense infrared thermal radiation evolved independently in several different families of snakes. Essentially, it allows these animals to “see” radiant heat at wavelengths between 5 and 30 μm to a degree of accuracy such that a blind …
15Background radiation — This article is about ionizing radiation. For microwave background radiation from space, see Cosmic background radiation and cosmic background. Thermal radiation emitted by Earth is not considered in this category because it is not ionizing.… …
