太陽及其缺失的顏色
The Sun and Its Missing Colors

發表日期:2025-12-07
人們仍然不知道為什麼太陽光會缺少一些顏色。 下面是太陽的所有可見光顏色,是將太陽光透過一個類似稜鏡的裝置後產生的。 該光譜由麥克馬斯特-皮爾斯太陽天文臺製作,首先顯示的是,雖然我們白色的太陽幾乎能發出各種顏色的光,但它最亮的是黃綠色的光。 光譜中的暗斑是由於太陽表面或上方的氣體吸收了下方發出的陽光。 由於不同型別的氣體吸收不同顏色的光,因此可以確定太陽由哪些氣體組成。 例如,氦氣於 1868 年首次在太陽光譜中被發現,後來才在地球上被發現。 如今,大部分光譜吸收線都已被確定,但並非全部。 鳳凰城免費 APOD 講座: 12 月 10 日星期三晚上 7 點
原文:It is still not known why the Sun's light is missing some colors. Here are all the visible colors of the Sun, produced by passing the Sun's light through a prism-like device. The spectrum was created at the McMath-Pierce Solar Observatory and shows, first off, that although our white-appearing Sun emits light of nearly every color, it appears brightest in yellow-green light. The dark patches in the featured spectrum arise from gas at or above the Sun's surface absorbing sunlight emitted below. Since different types of gas absorb different colors of light, it is possible to determine what gasses compose the Sun. Helium, for example, was first discovered in 1868 on a solar spectrum and only later found here on Earth. Today, the majority of spectral absorption lines have been identified - but not all.
