[漢羅] 中國念湖天頂 ê 雙生仔座流星雨

這寡流星是 tùi 佗位來--ê？ 以天頂 ê 方位來看，這个答案應該是指向 雙生仔座。 這就是是按怎 12 月主要 ê 流星雨叫做 雙生仔座流星雨，因為這寡流星雨攏是 ùi 一个 tī 雙生仔座 ê 輻射點 來--ê。 Ùi 3D 空間來看，這粒 編號 3200 ê 奇怪小行星 Phaethon 噴出來--ê 沙塗大細 ê 屑仔，就落 tī 踅太陽 ê 軌道頂懸，其中較倚 地球 ê 部份就出現 tī 雙生仔座 頭前。 地球 行過這粒小行星 ê 軌道 ê 時陣，因為這寡 落落來 ê 沙塗屑仔 出現 tī 雙生仔座方向，所以 輻射點 看起來就 tī 雙生仔座內底。 這張相片是 kā 幾若工前 tī 中國 念湖 暗暝翕--ê 足濟張 相片鬥做伙 ê 組合影像。 咱會當看著內底有超過 100 粒較光 ê 雙生仔座流星雨 ê 流星 軌跡。

[English] Geminids over China's Nianhu Lake

Where are all of these meteors coming from? In terms of direction on the sky, the pointed answer is the constellation of Gemini. That is why the major meteor shower in December is known as the Geminids -- because shower meteors all appear to come from a radiant toward Gemini. Three dimensionally, however, sand-sized debris expelled from the unusual asteroid 3200 Phaethon follows a well-defined orbit about our Sun, and the part of the orbit that approaches Earth is superposed in front of the constellation of Gemini. Therefore, when Earth crosses this orbit, the radiant point of falling debris appears in Gemini. Featured here is a composite of many images taken a few days ago through dark skies from Nianhu Lake in China. Over 100 bright meteor streaks from the Geminids meteor shower are visible.
