   Explanation: When the sun sets on September 7, the Full Moon will rise.
   And on that date denizens around much of our fair planet, including
   parts of Antarctica, Australia, Asia, Europe, and Africa can witness a
   total lunar eclipse, with the Moon completely immersed in Earth's
   shadow. As the bright Full Moon first enters Earth's shadow it will
   darken, finally taking on a reddish hue during the total eclipse phase.
   In fact, the color of the Moon during a total lunar eclipse is due to
   reddened light from sunrises and sunsets around planet Earth. The
   reddened sunlight is scattered by a dense atmosphere into the planet's
   otherwise dark central shadow. When the sun set on August 22, this
   telephoto snapshot of red skies, blue sea, and the Mangiabarche
   Lighthouse was captured from Sant'Antioco, Sardinia, Italy.
