Starlight is the light emitted by stars. It typically refers to visible electromagnetic radiation from stars other than the Sun observable from Earth during the night time although a component of starlight is observable from the Earth during the daytime. Sunlight is the term used for the Sun's starlight observed during daytime. During nighttime, albedo describes solar reflections from other Solar System objects including moonlight. Starlight is also a notable part of personal experience and human culture, impacting a diverse range of pursuits including poetry, astronomy, and military strategy.

  • 星光是恆星發射的光,它通常是指在地球夜間來自恆星可見光的電磁輻射;在白天,除了太陽之外其它天體的星光也可以觀測得到。 陽光這個術語是用在白天看見來自太陽的星光。在夜晚,反照率是描述來自太陽系的其它天體,包括月光,反射的陽光。 通過望遠鏡觀察和測量星光,是天文學許多領域的基礎,包括光度法和恆星光譜。星光也是許多個人經驗和人類文化中值得注意的,影響各種各樣的發展,包括詩歌、天文學、和軍事行動。 美國軍方在1950年代花費數以百萬計的美元,發展出星光夜視鏡,可以放大星光、被雲遮蔽的月光和來自植物的螢光,達到50,000倍,讓人可以在夜晚看得見。相較之前發射紅外線的系統,像是狙擊鏡,它是一種無源系統,不需要額外的發射光源來觀看。 在宇宙中的星光顏色平均是陰暗的黃白色,已被命名為宇宙拿鐵。 星光光譜學,恆星光譜的調查,最早在1814年由約瑟夫·弗勞恩霍夫開創。星光可以被分類為三種主要的光譜類型:連續譜、發射譜、和吸收譜。

  • Starlight is the light emitted by stars. It typically refers to visible electromagnetic radiation from stars other than the Sun observable from Earth during the night time although a component of starlight is observable from the Earth during the daytime. Sunlight is the term used for the Sun's starlight observed during daytime. During nighttime, albedo describes solar reflections from other Solar System objects including moonlight. Observation and measurement of starlight through telescopes is the basis for many fields of astronomy, including photometry and stellar spectroscopy. Hipparchus did not have a telescope or any instrument that could measure apparent brightness accurately, so he simply made estimates with his eyes. He sorted the stars into six brightness categories, which he called magnitudes. He referred to the brightest stars in his catalog as first-magnitudes stars, which were the brightest stars and those so faint he could barely see them were sixth-magnitude stars. 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 United States 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. The average color of starlight in the observable universe is a shade of yellowish-white that has been given the name Cosmic Latte. Starlight spectroscopy, examination of the stellar spectra, was pioneered by Joseph Fraunhofer in 1814. Starlight can be understood to be composed of three main spectra types, continuous spectrum, emission spectrum, and absorption spectrum.
