                    The Moon During a Total Lunar Eclipse

   Explanation: How does the Moon's appearance change during a total lunar
   eclipse? The [4]featured time-lapse video was digitally processed to
   keep [5]the Moon bright and centered during the 5-hour eclipse of
   [6]2018 January 31. At first the full moon is visible because only a
   [7]full moon can undergo a lunar eclipse. Stars move by in the
   background because the Moon orbits [8]the Earth during [9]the eclipse.
   The [10]circular shadow of the Earth is then seen moving across the
   Moon. The light blue hue of the shadow's edge is related to [11]why
   Earth's sky is blue, while the deep red hue of [12]the shadow's center
   is related to [13]why the Sun appears red when near the horizon.
   [14]Tomorrow night, people living in Eastern [15]Asia, [16]Australia,
   and much of [17]North America may [18]get to see a [19]Total Blood Moon
   Lunar Eclipse. Here the term [20]blood refers to the (likely) red
   [21]color of a fully eclipsed Moon.
