[漢羅] 金牛座 ê 獵戶座流星雨

哈雷彗星 ê 彗星編號是 1P/Halley，是歷史上頭一粒人類知影 ê 彗星，伊每 76 年會轉來內太陽系一擺。 這粒有名 ê 彗星頂擺轉來予咱看 ê 時陣是 1986 年。 毋過哈雷彗星留 tī 太空中 ê 塗粉粒，逐年會有兩擺 tī 地球天頂落塗粉雨，成做 5 月 ê 寶瓶座流星雨 kah 10 月 ê 獵戶座流星雨。 實際上，這張 10 月 23 透早翕--ê 慢速攝影相片，有翕著兩粒足光 ê 流星，這是 ùi 哈雷彗星 ê 塗粉粒蒸發出來--ê。 這張相片 ê 背景有滿滿 ê 天星，是 tī 金牛座分子雲 ê 方向。 這寡塗粉粒用一秒鐘 66 公里緊 ê 速度去挵地球大氣。 青色 ê 流星光巡就指向 流星雨 ê 輻射點，獵戶座 參宿四 ê 北方。 參宿四足光--ê，毋過無出現 tī 相片內底，伊 tī 相片倒爿下底閣較出去 ê 所在。 咱熟似 ê 昴宿星團，就 tī 這个厚塗粉天景 ê 正爿。

[English] Orionids in Taurus

History's first known periodic comet, Comet Halley (1P/Halley), returns to the inner Solar System every 76 years or so. The famous comet made its last appearance to the naked-eye in 1986. But dusty debris from Comet Halley can be seen raining through planet Earth's skies twice a year during two annual meteor showers, the Eta Aquarids in May and the Orionids in October. In fact, an unhurried series of exposures captured these two bright meteors, vaporizing bits of Halley dust, during the early morning hours of October 23 against a starry background along the Taurus molecular cloud. Impacting the atmosphere at about 66 kilometers per second their greenish streaks point back to the shower's radiant just north of Orion's bright star Betelgeuse off the lower left side of the frame. The familiar Pleiades star cluster anchors the dusty celestial scene at the right.
