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 complex jumble of colorful gas and dark dust dominate a bright
        field of stars. Please see the explanation for more detailed
                                information.

                     NGC 2170: Angel Nebula Abstract Art
                 Image Credit & Copyright: [3]David Moulton

   Explanation: Is this a painting or a photograph? In this celestial
   [4]abstract art composed with a cosmic brush, dusty nebula [5]NGC 2170,
   also known as the Angel Nebula, shines just above the image center.
   Reflecting the light of nearby hot stars, [6]NGC 2170 is joined by
   other bluish [7]reflection nebulae, a red [8]emission region, many dark
   [9]absorption nebulae, and a backdrop of [10]colorful stars. Like the
   common household items that [11]abstract painters often choose for
   their subjects, the clouds of gas, dust, and hot stars [12]featured
   here are also commonly found in a setting like this one -- a massive,
   star-forming molecular cloud in the constellation of the [13]Unicorn
   ([14]Monoceros). The giant [15]molecular cloud, [16]Mon R2, is
   impressively close, [17]estimated to be only 2,400 [18]light-years or
   so away. At that distance, this [19]canvas would be over 60 light-years
   across.
