Description: 光學天文學主要研究和觀測宇宙（恆星、行星、矮行星、小行星等）輻射的近紅外線、可見光和紫外線。將這三種電磁輻射放在一起的原因是，天文學家最初為觀測來自天體的可見光而建造的帶有玻璃鏡片和/或金屬鏡面的光學望遠鏡，同樣也適用於觀測近紅外線或紫外線。此外，地球大氣層不僅對可見光是透明的，而且對直接相鄰的紅外線和紫外線區域也是透明的，因此可以從地面同時對這三種輻射進行觀測。最後，天文學家用於可見光觀測的相機芯片也同時能探測到近紅外線和紫外線。呲上所述，天文學家用於觀測可見光的望遠鏡和儀器同樣適用於近紅外和紫外線觀測。因此，天文學家們用一個術語，即 "光學天文學"，來統稱對電磁波譜這一範圍的觀測。形容詞 "光學 "也用於描述光譜範圍，如 "光譜的光學部分"。在這一範圍內的觀測就是 "光學觀測"。
