Starlight is light emitted by stars. 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, including photometry and stellar spectroscopy. Starlight is also a notable part of personal experience and human culture, impacting a diverse range of pursuits including poetry, astronomy, and military strategy.
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. 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.
An example of poetic use of starlight in literature composition is the phrase "frosty starlight". Starlight is (currently) a shade of beige known as Cosmic Latte.
