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 a close up of the Pelican Nebula
   highlighted by several dark pillars, one of which spouts jets on either
       side. Please see the explanation for more detailed information.

   Explanation: What dark structures arise within the Pelican Nebula? On
   the whole, the nebula appears like a bird ([4]a pelican) and is seen
   toward the constellation of a different bird: [5]Cygnus, a Swan. But
   inside, the [6]Pelican Nebula is a place lit up by new stars and
   [7]befouled by dark dust. Smoke-sized [8]dust grains start as simple
   carbon compounds formed in the cool atmospheres of young stars but are
   dispersed by [9]stellar winds and [10]explosions. Two impressive
   [11]Herbig-Haro jets are seen emitted by the star HH 555 on the right,
   and these jets are helping to [12]destroy the [13]light year-long dust
   [14]pillar that contains it. Other pillars and jets are also visible.
   The [15]featured image was [16]scientifically-colored to emphasize
   light emitted by small amounts of heavy elements in a nebula made
   predominantly of the light elements [17]hydrogen and [18]helium. The
   [19]Pelican Nebula (IC 5067 and IC 5070) is about 2,000 [20]light-years
   away and can be found with a small telescope to the northeast of the
   bright star [21]Deneb.
