[漢羅] 流星崩去 會發出化學光

流星有可能有足濟色。 是講 人類 ê 目睭 通常是無法度看著遐爾濟色，毋過 kha-mé-lah 是會使。 這張圖 是一粒 火流星，是一粒當咧崩去 ê 流星。 伊毋但是攝影師 看過 上光 ê 流星，嘛是上濟色 ê 流星。 這粒流星是 7 月中 tī 奧地利 Hochkar 山頂 chhāi kha-mé-lah 欲翕銀河系中央帶 ê 時陣，順紲翕著--ê。 這寡 輻射沙塗，真有可能是 彗星 抑是 小行星 tī 足久以前擲出來--ê。 是講 in 嘛誠衰，煞落落來 地球 ê 大氣層。 流星 ê 色光 定定是 流星 崩去 ê 時陣，放出來 ê 離子化 化學元素。 青藍色 ê 通常是 ùi 鎂 來--ê，kha-lú-sìm-muh 會輻射出茄仔色 ê 光，白銅 會發出青光。 毋過，紅光通常是 ùi 地球大氣層內底 ê 高能 窒素 kah 酸素 來--ê。 這个遮爾光 ê 火流星 一目𥍉 就無去矣，猶無到 1 秒咧。 毋過伊有留一條 去予風吹振動 ê 離子痕跡，這咱就看會著啊，差不多有 1 分鐘久。

[English] Chemicals Glow as a Meteor Disintegrates

Meteors can be colorful. While the human eye usually cannot discern many colors, cameras often can. Pictured here is a fireball, a disintegrating meteor that was not only one of the brightest the photographer has ever seen, but colorful. The meteor was captured by chance in mid-July with a camera set up on Hochkar Mountain in Austria to photograph the central band of our Milky Way galaxy. The radiant grit, likely cast off by a comet or asteroid long ago, had the misfortune to enter Earth's atmosphere. Colors in meteors usually originate from ionized chemical elements released as the meteor disintegrates, with blue-green typically originating from magnesium, calcium radiating violet, and nickel glowing green. Red, however, typically originates from energized nitrogen and oxygen in the Earth's atmosphere. This bright meteoric fireball was gone in a flash -- less than a second -- but it left a wind-blown ionization trail that remained visible for almost a minute.
