[漢羅] 平流層 ê 北極光

Tī 這張 1 月 15 翕 ê 夜空相片，北極光 就 tī 地球平流層 咧發光。 這張 5 秒鐘 ê 孤張感光相片，是手扞 kha-mé-lah 翕飛 tī 加拿大 Winnipeg 天頂 ê 飛龍機。 感光 ê 時陣，tī 飛龍機 高速飛行下底 ê 燈火，出現五彩 ê 光跡。 Tī 遠方地平線頂懸，去予 地球極區 磁場 加速 ê 高能粒子，激發酸素原子，產生閃閃爍爍 ê 北極光。 極光發出 ê 青光，是 tī 海拔 100 - 300 公里懸 ê 所在產生--ê。 紅色是 tī 較低大氣密度、較懸海拔 ê 所在產生--ê。 銀河盤頂懸暗暗 ê 恆星 tī 夜空中 chiâⁿ 做一條彎弓。 北天 ê 仙女座星系，予這个夜空擴展到 銀河系以外 ê 世界。 仙女座星系是 kah 咱銀河系上倚 ê 大型捲螺仔星系。 這个霧霧 ê 星系，就 tī 相片倒爿頂懸。

[English] Northern Lights from the Stratosphere

Northern lights shine in this night skyview from planet Earth's stratosphere, captured on January 15. The single, 5 second exposure was made with a hand-held camera on board an aircraft above Winnipeg, Canada. During the exposure, terrestrial lights below leave colorful trails along the direction of motion of the speeding aircraft. Above the more distant horizon, energetic particles accelerated along Earth's magnetic field at the planet's polar regions excite atomic oxygen to create the shimmering display of Aurora Borealis. The aurora's characteristic greenish hue is generated at altitudes of 100-300 kilometers and red at even higher altitudes and lower atmospheric densities. The luminous glow of faint stars along the plane of our Milky Way galaxy arcs through the night, while the Andromeda galaxy extends this northern skyview to extragalactic space. A diffuse hint of Andromeda, the closest large spiral to the Milky Way, can just be seen to the upper left.
