                         Astronomy Picture of the Day

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

                      Earthrise: A Video Reconstruction
            Image Credit: NASA [2] , SVS [3] , Apollo 8 [4]  Crew;
 Lead Animator: Ernie Wright [5] ; (USRA [6] ); Music: C Major Prelude [7]  by
                          Johann Sebastian Bach [8]

Explanation: About 12 seconds into this video, something unusual happens. The
Earth begins to rise. Never seen by humans before, the rise of the Earth [9]
over the limb of the Moon occurred 50 years ago tomorrow and surprised and
amazed the crew of Apollo 8 [10] . The crew immediately scrambled [11]  to
take still images of the stunning vista [12]  caused by Apollo 8 [13] 's orbit
around the Moon. The featured video [14]  is a modern reconstruction of the
event [15]  as it would have looked were it recorded with a modern movie
camera. The colorful orb of our Earth [16]  stood out as a familiar icon
rising [17]  above a distant and unfamiliar moonscape [18] , the whole scene
the conceptual reverse of a more familiar moonrise [19]  as seen from Earth.
To many, the scene also spoke about the unity of humanity: that big blue
marble [20]  -- that's us -- we all live there. The two-minute video [21]  is
not time-lapse -- this is the real speed of the Earth rising through the
windows of Apollo 8 [22] . Seven months and three missions later, Apollo 11
[23]  astronauts would not only circle Earth's moon, but land on it [24] .
