[漢羅] 雙生仔座 ê 雙生仔流星雨

這寡流星是 ùi 佗位來 ê？ 按照天頂 ê 方位來看，應該是 ùi 雙生仔 座 來 ê。 這就是是按怎 12 月 ê 流星會叫做 雙生仔座流星雨。 因為流星雨攏是 ùi 仝一个輻射點來 ê，這个 輻射點 tī 雙生仔座 內底。 毋閣 ùi 立體 ê 角度來看，這个無四常 ê 小行星 Phaethon 3200 噴出來 ê 沙塗粒，攏踅太陽 ê 軌道 leh 行。 伊倚地球彼爿軌道拄仔好疊 tī 雙生仔座 ê 頭前。 所以地球若是 行到這个軌道，流星屑仔 ê 輻射點 to̍h 會出現 tī 雙生仔座。 這張相片是 2020 年 12 月 14 這暗翕 ê 雙生仔座流星雨。 是 kā 200 外粒 足光 ê 流星 tī 天頂 行過 ê 光巡 疊做伙 ê。 11 月上重要 ê 流星 雨是 獅仔座流星雨，下暗 kah 明仔暗會上濟。 是講真不幸，今年 ê 流星會較暗，因為伊 上濟 ê 時陣是 tī 透早，而且閣拄著膨月，按呢會較歹 看著。 毋閣，每一點鐘應該攏會看著幾若粒 較光 ê 獅仔座流星。

[English] Geminids from Gemini

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, a composite of many images taken during the 2020 Geminids meteor shower shows over 200 bright meteors that streaked through the sky during the night December 14. The best meteor shower in November, the Leonids, peaks tonight and tomorrow. Unfortunately, this year, dim meteors during the early-morning peak will be hard to see against a sky lit by a bright gibbous moon. Still, a few bright Leonid meteors should be visible each hour.
