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 starfield surrounds a colorful nebula that glows both red and blue
    but is filled with dust, both light brown and dark brown. Please see
               the explanation for more detailed information.

   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 [12]stars featured
   [13]here are also commonly found in a setting like this one -- a
   massive, star-forming molecular cloud in the [14]constellation of the
   [15]Unicorn ([16]Monoceros). The giant [17]molecular cloud [18]Mon R2,
   is impressively close, [19]estimated to be only 2,400 [20]light-years
   or so away. At that distance, this [21]canvas would be over 60
   [22]light-years across.
