如何識別天空中的那道光
How to Identify that Light in the Sky

天空中的那道光是什麼？人類最常見的問題之一的答案可能會從一些快速的觀察中浮現出來。 例如，它是在移動還是在閃爍？如果是，而且你住在城市附近，那麼答案通常是飛機，因為飛機數量眾多，而且很少有星星和衛星亮到足以在城市人造燈光的強光下被看到。如果不是，而且你住在遠離城市的地方，那亮光很可能是金星或火星等行星--前者只能在黎明前或黃昏後出現在地平線附近。 有時，遠處飛機在地平線附近的低視距運動會讓人難以分辨明亮的行星，但即使是這樣，通常也能透過飛機在幾分鐘內的運動來辨別。還不確定嗎？ 特色圖表給出了時而幽默、時而準確的評估。 有心的天空愛好者可能會注意到--我們也鼓勵他們提供--禮貌的更正。 圖表翻譯：義大利語、德語、拉脫維亞語、波斯語、波蘭語、西班牙語和土耳其語
原文：What is that light in the sky? The answer to one of humanity's more common questions may emerge from a few quick observations. For example -- is it moving or blinking? If so, and if you live near a city, the answer is typically an airplane, since planes are so numerous and so few stars and satellites are bright enough to be seen over the glare of artificial city lights. If not, and if you live far from a city, that bright light is likely a planet such as Venus or Mars -- the former of which is constrained to appear near the horizon just before dawn or after dusk. Sometimes the low apparent motion of a distant airplane near the horizon makes it hard to tell from a bright planet, but even this can usually be discerned by the plane's motion over a few minutes. Still unsure? The featured chart gives a sometimes-humorous but mostly-accurate assessment. Dedicated sky enthusiasts will likely note -- and are encouraged to provide -- polite corrections.
