Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

   Explanation: A photographer in silhouette stands in bright moonlight as
   [6]the Full Moon rises in this well-planned telephoto image. Of course,
   the Full Moon is normally the brightest lunar phase. But on [7]November
   18/19, the Full Moon's light will be dimmed during a deep partial lunar
   eclipse seen across much of planet Earth. At maximum eclipse only a few
   percent of the lunar disk's diameter should remain outside the Earth's
   dark umbral shadow when the Moon slides close to the shadow's southern
   edge. Near apogee, the farthest point in its orbit, the Moon's motion
   will be slow. That should make this second [8]lunar eclipse of 2021 an
   exceptionally long partial lunar eclipse. For most of [9]North America
   the eclipse partial phases will be visible in predawn hours. [10]Since
   eclipses tend to come in pairs, this lunar eclipse will be followed by
   a solar eclipse in two weeks on December 4.
