Glossary term: 可見光譜
Description: 波長在 380 到 750 納米之間的電磁輻射是人眼可見的，稱為可見光。如果把電磁輻射分成光譜，按波長排列所有不同種類的輻射，並繪製出每個波長區域內到達我們的輻射量，那麼光譜中介於 380 納米和 750 納米之間的部分就是可見光譜。從波長最短到最長，我們可以看到紫光、靛藍光、藍光、綠光、黃光、橙光和紅光，它們連續排列在一起--這就是彩虹的顏色，大自然通過太陽光在小水滴中的折射，形成了這樣的光譜組成。

The Pillars of Creation in comparison
Caption: The 'Pillars of Creation' are a renowned astronomical feature situated within the Eagle Nebula in the Serpens constellation. The illustration provides a direct comparison between images captured by the Hubble Space Telescope (HST) and the James Webb Space Telescope (JWST), showcasing the pillars, which span several light years in diameter, in both visible light (also known as optical light) and infrared light. On the left are the pillars as seen by Hubble in visual light, taken in 2014. It displays dark pillars against an opaque background, with only a handful of visible stars. Conversely, the counterpart on the right is Webb’s near-infrared view published in 2022, penetrating the dust and revealing numerous stars of varying sizes.
Their distance from Earth is approximately 6,500 to 7,000 light years. Within these pillars, new stars are constantly forming, making them a subject of extensive study by astronomers. Composed mostly of cool molecular hydrogen and small amounts of interstellar dust, they are subject to erosion by the intense ultraviolet radiation emitted by nearby massive and newborn stars, a process known as photoevaporation.
