                    The Moon During a Total Lunar Eclipse
               Video Credit: [3]Wang Letian & [4]Zhang Jiajie

   Explanation: How does the Moon's appearance change during a total lunar
   eclipse? The [5]featured time-lapse video was digitally processed to
   keep [6]the Moon bright and centered during the 5-hour [7]eclipse of
   2018 January 31. At first the [8]full moon is visible because only a
   full moon can undergo a [9]lunar eclipse. Stars move by in the
   background because the Moon orbits [10]the Earth during [11]the
   eclipse. The [12]circular shadow of the Earth is then seen moving
   across the Moon. The light blue hue of the shadow's edge is related to
   [13]why Earth's sky is blue, while the deep red hue of [14]the shadow's
   center is related to [15]why the Sun appears red when near the horizon.
   Tomorrow, people living from southeast Asia, across [16]the Pacific, to
   the southwest Americas may [17]get to see a Blood Supermoon [18]Total
   Lunar Eclipse. Here the term blood refers to the (likely) red [19]color
   of the fully eclipsed Moon, while the term [20]supermoon indicates the
   Moon's slightly high angular size -- due to being relatively close to
   the Earth in its [21]slightly elliptical orbit.
