   Explanation: What's happening in the [4]Statue of Liberty nebula?
   [5]Bright stars and [6]interesting molecules are forming and being
   [7]liberated. The [8]complex nebula resides in the star forming region
   called RCW 57, and besides the iconic monument, to some looks like a
   [9]flying superhero or a [10]weeping angel. By digitally removing the
   stars, [11]this image showcases dense knots of [12]dark interstellar
   dust, fields of [13]glowing hydrogen gas ionized by these stars, and
   [14]great loops of gas expelled by dying stars. A [15]detailed study of
   NGC 3576, also known as [16]NGC 3582 and [17]NGC 3584, uncovered at
   least 33 massive stars in the end stages of formation, and the clear
   presence of the complex carbon molecules known as [18]polycyclic
   aromatic hydrocarbons (PAHs). PAHs are thought to be created in the
   cooling gas of [19]star forming regions, and their development in the
   [20]Sun's formation nebula five billion years ago may have been an
   important step in the [21]development of life on Earth.
