Starlight
For other uses, see Starlight (disambiguation).
Starlight is light emitted by stars.[1] It typically refers to visible electromagnetic radiation coming from stars other than the Sun, during the night, although starlight technically forms a minor component of daylight as well. Observation and measurement of starlight through telescopes is the basis for many fields of astronomy,[2] including photometry and stellar spectroscopy.[3] Starlight is also a notable part of personal experience and human culture, impacting a diverse range of pursuits including poetry[4], astronomy[2], and military strategy.[5]
The U.S. Army spent millions of dollars in the 1950s and onward to develop a starlight scope, that could amplify starlight, moonlight filtered by clouds, and the fluorescence of rotting vegetation about 50,000 times to allow a person to see in the night.[5] In contrast to previously developed active infrared system such as sniperscope, it was a passive device and did not require additional light emission to see.[5]
An example of poetic use of starlight in literature composition is the phrase "frosty starlight".[4] Starlight is (currently) a shade of beige known as Cosmic Latte.
Starlight spectroscopy, examination of the stellar spectra, was pioneered by Joseph Fraunhofer in 1814.[3] Starlight can be understood to be composed of three main spectra types, continuous spectrum, emission spectrum, and absorption spectrum.[1]
