Explanation: The Full Moon of October 9th was the second Full Moon after the northern hemisphere autumnal equinox, traditionally called the Hunter’s Moon. According to lore, the name is a fitting one because this Full Moon lights the night during a time for hunting in preparation for the coming winter months. In this snapshot, a nearly full Hunter’s Moon was captured just after sunset on October 8, rising in skies over Florida’s Space Coast. Rising from planet Earth a Falcon 9 rocket pierces the bright lunar disk from the photographer’s vantage point. Ripples and fringes along the edge of the lunar disk appear as supersonic shock waves generated by the rocket’s passage change the atmosphere’s index of refraction.

说明: 10月9日的满月，是北半球秋分之后的第二个满月，传统上有狩月之称。这个自古流传的名字其实很贴切，因为这轮满月照亮了为即将来临的冬季渡冬准备的狩猎季之夜晚。这张摄于10月8日日落后的影像，捕捉到了几乎满相的狩月，在佛罗里达州太空海岸的天空冉冉升起。从摄影者所在的位置看出去，由地面发射升空的猎鹰9号火箭看似刺穿了明亮的月盘。而月盘的边缘之所以会出现波纹和条纹，则是因为路过的火箭所产生的超音速震波，改变了大气的折射率所致。
