原文:
rth’s annual Geminid meteor shower did not disappoint, peaking before dawn on December 14 as our fair planet plowed through dust from active asteroid 3200 Phaethon. Captured in this southern hemisphere nightscape the meteors stream away from the shower’s radiant in Gemini. To create the image, many individual frames recording meteor streaks were taken over period of 5 hours. In the final composite they were selected and registered against the starry sky above the twin 6.5 meter Magellan telescopes of Carnegie Las Campanas Observatory in Chile. Rigel in Orion, and Sirius shine brightly as the Milky Way stretches toward the zenith. Near Castor and Pollux the twin stars of Gemini, the meteor shower’s radiant is low, close to the horizon. The radiant effect is due to perspective as the parallel meteor tracks appear to converge in the distance. Gemini’s meteors enter Earth’s atmosphere traveling at about 22 kilometers per second.

🌌 在12月14日清晨，地球的年度雙子座流星雨達到巔峰，當我們的星球衝過來自活躍小行星3200 Phaethon的塵埃時，流星雨的景象讓人驚嘆。在這張南半球的夜空圖像中，流星從雙子座的輻射區散發而出。這幅圖像是通過一段長達5小時的拍攝過程中多個個別畫面進行合成而成，將錄製下來的流星條紋選出並與智利卡內基拉斯坎帕納斯天文台的雙6.5米馬哈冉望遠鏡上方的星空對齊。獨立星座獨角獸的藍星Rigel和夜空中最亮的星星Sirius閃閃發光，而銀河系則延伸至天頂。雙子座的兩顆雙星Castor和Pollux讓流星雨的輻射區低於地平線。這種輻射效果是由於透視的原因，平行的流星軌跡在遠方似乎收斂。雙子座的流星以約每秒22公里的速度進入地球大氣層。
