原文:
Not a bright comet, 67P/Churyumov-Gerasimenko now sweeps slowly through planet Earth’s predawn skies near the line-up of planets along the ecliptic. Still, this composite of telescopic images follows the comet’s progress as it moves away from the Sun beyond the orbit of Mars, from late September (left) through late November (far right). Its faint but extensive coma and tails are viewed against the colorful background of stars near the eastern edge of the constellation Leo. A year ago, before its perihelion passage, the comet was less active, though. Then the Rosetta mission’s lander Philae made its historic landing, touching down on the surface of the comet’s nucleus.

🌌 不太耀眼的彗星 67P/Churyumov-Gerasimenko 現在正慢慢穿越地球的黎明天空，靠近行星沿著黃道的排列。這幅望遠鏡拍攝的合成圖像跟隨彗星的進展，顯示它從9月底（左）到11月底（右）移動遠離太陽，超越火星軌道。它微弱但廣泛的彗發和尾巴在獅子座東邊的星空背景中顯示出來。一年前，在其近日點通過之前，這顆彗星活動較少，而此時羅塞塔號任務的著陸器 Philae 則成功降落，歷史性地觸及了彗星核的表面。
