   Explanation: [4]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 [5]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 [6]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.
