Lyrid of the Lake

Explanation: In the early hours of April 24 this bright Lyrid meteor flashed along the central Milky Way. For a moment, it cast a bright reflection across Lake Nian, Yunnan province, China. The annual Lyrid meteor shower, one of the oldest known, is active in late April, as our fair planet plows through dust left along the orbit of long-period comet Thatcher. The trail of the bright fireball points back toward the shower’s radiant in the constellation Lyra high in the northern springtime sky and off the top of the frame. Just rising in that starry sky, light from a third quarter moon also cast a glow on the peaceful waters of the lake.

说明: 这颗明亮的天琴流星,在4月24日的凌晨,沿着银河系的中央盘面掠过长空。在那瞬间,它于中国云南省的念湖投下一道明亮的倒影。在每一年的4月下旬,每当地球穿过长周期彗星撒切尔在轨道上留下的尘埃之时,就会带来活跃期就在此时、现知最古老流星雨之一的天琴流星雨。这颗明亮火流星的轨迹,回指高悬在北天春季天空中、位在影像顶缘外头的天琴流星雨之辐射点。而刚东升下弦月的月光,也在平滑如镜的湖水上映出明亮的倒影。
