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]A dark starfield is shown with several brown nebulas. Many of the
    nebulas appear to have unusual shapes, with one possibly resembling a
    bat, while other may resemble people. Please see the explanation for
                         more detailed information.

   Explanation: Do any shapes seem to jump out at you from this
   interstellar field of stars and dust? The [4]jeweled expanse, filled
   with faint, starlight-reflecting clouds, drifts through the night in
   the royal constellation of [5]Cepheus. Far from your own neighborhood
   on planet [6]Earth, these [7]ghostly apparitions lurk along the plane
   of the Milky Way at the edge of the [8]Cepheus Flare molecular cloud
   complex some 1,200 [9]light-years away. Over two [10]light-years across
   and brighter than the other spooky [11]chimeras, [12]VdB 141 or Sh2-136
   is also known as the [13]Ghost Nebula, seen toward the bottom of the
   [14]featured image. Within the [15]reflection nebula are the telltale
   signs of dense cores [16]collapsing in the early [17]stages of star
   formation.
