[漢羅] 銀河 ê 彩色氣輝帶

是按怎天頂發出這款光?敢若是有足大 ê 虹 tī 天頂一輾一輾疊出去按呢? 這是 氣輝 啦! 其實空氣隨時攏 leh 發光,是咱看袂著。 毋閣,若是有風暴倚近,可能會 tī 地球大氣 造成明顯 ê 波紋。 這款 重力波 to̍h 親像是 kā 石頭擲入去平靜 ê 水 內底產生波動仝款,伊是 tī 空氣內底產生波動。 紅色 ê 氣輝 可能是 tī 87 公里懸 ê OH 分子 去予太陽 ê 紫外光 激發,發出 ê 光。 毋閣柑仔色 kah 青色 ê 氣輝 可能是 閣較懸 ê kah 酸素 原子 發出 ê 光。 這个攝影師幾若年前 tī 中國 駛車到 青海省 Keluke 湖 附近 ê 時陣,本底是注意著 銀河系 美麗 ê 中央帶。 伊 kā 車停 leh,落來翕相。 結果伊 ê kha-mé-lah 敏感度袂䆀,翕出來 ê 相片 竟然 煞看會著 足明顯 ê 氣輝帶,而且規个天頂攏有。 這張相片有用數位加強 ê 方式 kā 色光變甲閣較顯目。

[English] Colorful Airglow Bands Surround Milky Way

Why would the sky glow like a giant repeating rainbow? Airglow. Now air glows all of the time, but it is usually hard to see. A disturbance however -- like an approaching storm -- may cause noticeable rippling in the Earth's atmosphere. These gravity waves are oscillations in air analogous to those created when a rock is thrown in calm water. Red airglow likely originates from OH molecules about 87-kilometers high, excited by ultraviolet light from the Sun, while orange and green airglow is likely caused by sodium and oxygen atoms slightly higher up. While driving near Keluke Lake in Qinghai Provence in China a few years ago, the photographer originally noticed mainly the impressive central band of the Milky Way Galaxy. Stopping to photograph it, surprisingly, the resulting sensitive camera image showed airglow bands to be quite prominent and span the entire sky. The featured image has been digitally enhanced to make the colors more vibrant.
