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.

   [2]The featured image shows an orange sky with clouds across the bottom
    and several bright stars near the top center. Just at the top of the
    cloud deck on the left is a half-lit Moon. Please see the explanation
                       for more detailed information.

   Explanation: Nine days ago, two quite different sky icons were imaged
   rising together. Specifically, Earth's Moon shared the eastern sky with
   the [5]sister stars of the Pleiades cluster, as viewed from [6]Alberta,
   [7]Canada. Astronomical images of the [8]well-known Pleiades often show
   the star cluster's alluring blue [9]reflection nebulas, but here they
   are washed-out by the orange [10]moonrise sky. The half-lit Moon, known
   as a [11]quarter moon, is overexposed, although the outline of the dim
   lunar night side can be seen by illuminating [12]earthshine, light
   first reflected from the Earth. The [13]featured image is a composite
   of [14]eight successive exposures with brightnesses adjusted to match
   what the [15]human eye would see. The Moon passes [16]nearly -- or
   [17]directly -- in front of [18]the Pleaides once a month.
