   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.
