Note: What happened to the statue of the Liberty Goddess? Bright stars and interesting elements are forming and release. This complex nebula is located in a star formation area called RCW57. In addition to looking at the statue of Liberty, some people also think that it looks like a flying superhero or an angel who is crying. This pseudo -colored photo removed the stars through digital technology, highlighting the dense dark interstellar dust knot, the glowing hydrogen permeability area of ​​the stars, and the huge gas ring sprayed by the dying star. Detailed studies on NGC3576 (also known as NGC3582 and NGC3584) found that at least 33 large -quality stars are at the end of its formation stage, and there are obvious existence of complex carbon molecules called polygon aromatic hydrocarbons (PAHS). Poor aromatic hydrocarbons are considered to be produced in the cooling gases in the formation area of ​​a star. The development of them in the nebula of 5 billion years ago may be an important part of the earth's life.
