                      NGC 2170: Angel Nebula Still Life
              Image Credit & Copyright: [3]Juan Lozano de Haro

   Explanation: Is this a painting or a photograph? In this classic
   celestial [4]still life composed with a cosmic brush, dusty nebula
   [5]NGC 2170, also known as the [6]Angel Nebula, shines near the image
   center. Reflecting the light of nearby hot stars, [7]NGC 2170 is joined
   by other bluish [8]reflection nebulae, a red [9]emission region, many
   dark [10]absorption nebulae, and a backdrop of [11]colorful stars. Like
   the common household items that [12]still life painters often choose
   for their subjects, the clouds of gas, dust, and hot stars [13]featured
   here are also commonly found in this setting -- a massive, star-forming
   molecular cloud in the constellation of the [14]Unicorn
   ([15]Monoceros). The giant [16]molecular cloud, [17]Mon R2, is
   impressively close, [18]estimated to be only 2,400 [19]light-years or
   so away. At that distance, this [20]canvas would be over 60 light-years
   across.
