Explanation: Nature photographers and other fans of planet Earth always look forward to the blue hour. That’s the transition in twilight, just before sunrise or after sunset, when the Sun is below the horizon but land and sky are still suffused with a beautiful blue light. After sunset on August 21, this blue hour snapshot captured the nearly full Moon as it rose opposite the Sun, above the rugged Italian Alps from Cortina d’Ampezzo, Italy. Sharing bluish hues with the sky, the rocky pyramid of Monte Antelao, also known as the King of the Dolomites, is the region’s prominent alpine peak. The moonlight is yellow, but even so this full Moon was known to some as a seasonal Blue Moon. That’s because by one definition the third full Moon of a season with four full moons in it is called a Blue Moon. Recognizing a season as the time between a solstice and an equinox, this season’s fourth full Moon will be rising in the blue hour of September 20, just before September’s equinox.

说明: 自然景观摄影者与其他地球景观的粉丝，通常都很期待蓝色时段。这段时间是指暮曙光时分里，在日出前或日落后的这段期间，该时太阳在地平面之下，但大地与天空全都沐浴在泛蓝的美丽辉光里。这幅摄于8月21日落后的蓝色时段影像，记录近满相、与太阳反向的月轮，从义大利．科尔蒂纳丹佩佐镇附近的嵯峨阿尔卑斯山后方升起。这座沐浴在泛蓝晕光里的金字塔状安特拉奥峰，是此区最高耸的阿尔卑斯山峰，有多洛米蒂山脉之王的称号。虽然这轮明月在散发泛黄的月光，不过就连它也有这季的蓝月之称。从至点到分点之间的时日为一季，而在拥有4轮满月的季里，第三轮满月称为蓝月。在目前的季节里，第四轮满月将在今年秋分的前一天、9月20日的蓝色时段升起。
