Explanation:Fans of planet Earth probably recognize the Matterhorn in the foreground ofthis night skyscape. Famed in mountaineering history, the 4,478 meter Alpinemountain stands next to the totally eclipsed Moon. In spite of -22 degree C temperatures,the inspired scene was captured on the morning of January 21 from the mountainsnear Zermatt, Switzerland. Different exposures record the dim red lightreflected by the Moon fully immersed in Earth's shadow. Seen directly above thefamous Alpine peak, but about 600 light-years away, are the stars of thePraesepe or Beehive star cluster also known as Messier 44. An added reward tothe cold eclipse vigil, a bright and colorful meteor flashed below thetemporarily dimmmed Moon, just tracing the Matterhorn's north-eastern climbingroute along Hornli ridge.

马特宏峰、月亮和流星

解释：在这幅夜空风景照的前景中，地球景观的爱好者可能会辨认出马特宏峰。在登山史上非常著名，这座4478米高的阿尔卑斯山峰耸立在正发生全食的月亮旁边。零下22摄氏度，这个令人激动的场景于1月21日早晨在瑞士泽尔马特附近的山区被摄影师所捕捉。阿尔卑斯主峰的上方可以看到约600光年远的蜂巢星团（又名M44）的众多恒星。作为对寒冷的月食守夜的额外奖赏，一颗明亮多彩的流星从暂时变暗的月亮下面，刚好沿着马特宏峰东北的登山路线宏恩立山脊划过。
