[漢羅] 彗星 67P 頂懸 ê 雪

你若是徛 tī 週期性彗星 67P/Churyumov-Gerasimenko ê 山壁頂懸，並袂去予這場暴風雪擋咧。 Rosetta 太空船 tī 2016 年 6 月踅這粒彗星 ê 時陣，伊 ê 狹視角 kha-mé-lah 就 tī 彗星表面 頂懸 附近，紀錄著這寡 tī 視野內底看起來敢若是咧落雪 ê 塗粉 kah 冰粒。 有一寡 tī 影像內底較光 ê 光斑，可能是因為高能紮電粒子 抑是 宇宙線 去舂著 kha-mé-lah。 有一寡是 tī 大隻狗星座（大犬座）方向 實密 ê 背景星。 影片 內底 ê 背景星較好揣，因為 in ê 光巡 是 ùi 頂懸到下底。 這支精彩 ê 影片是 Rosetta 太空船 tiàm 離 彗核 13 公里遠 ê 所在，kā 25 分鐘內翕 ê 33 張 連紲影像 合成 ê 影片。 2016 年 9 月 ê 時陣，Rosetta 太空船完成伊最後 ê 任務了後，成功控制伊家己去挵 彗星 67P。 彗核就變做是 Rosetta 太空船 上落尾安息 ê 所在。

[English] The Snows of Churyumov-Gerasimenko

You couldn't really be caught in this blizzard while standing by a cliff on periodic comet 67P/Churyumov-Gerasimenko. Orbiting the comet in June of 2016, the Rosetta spacecraft's narrow angle camera did record streaks of dust and ice particles similar to snow as they drifted across the field of view close to the camera and above the comet's surface. Still, some of the bright specks in the scene are likely due to a rain of energetic charged particles or cosmic rays hitting the camera, and the dense background of stars in the direction of the constellation of the Big Dog (Canis Major). In the video, the background stars are easy to spot trailing from top to bottom. The stunning movie was constructed from 33 consecutive images taken over 25 minutes while Rosetta cruised some 13 kilometers from the comet's nucleus. In September 2016, the nucleus became the final resting place for the Rosetta spacecraft after its mission was ended with a successful controlled impact on 67P/Churyumov-Gerasimenko.
