Glossary term: 電磁輻射
Description: 當19世紀的物理學家在描述電磁現象時發現,即使在附近沒有電荷的情況下,電場和磁場也能以光速在空間傳播。這些波被稱為電磁波或電磁輻射。基本電磁波可根據其波長進行分類,由此產生的電磁波譜從較短波長到較長波長包括:伽馬射線、X射線、紫外線、可見光、紅外線、亞毫米波和射電波(包括毫米波/微波)。來自遙遠天體的電磁輻射是天文學家了解這些天體的最重要的信息來源。

黑體輻射
Caption: 不同溫度黑體的輻射麯綫。x 軸錶示波長,y 軸錶示黑體錶麵每平方米在每個波長下每秒發射的能量。
溫度越高的物體,波長越短,發齣的最大能量光也越藍。盡管圖中最冷的天體發齣的紅光達到峰值,但其他較熱的天體發齣的紅光都比最冷的天體多。

虛綫顯示的是現代量子力學之前的經典理論所預測的輻射量。對於任何溫度高於零的黑體,這一預測在較短波長處都趨於無窮大,被稱為 "紫外綫災難"。
