... A detailed study of NGC 3582 , also known as NGC 3584 and NGC 3576 , uncovered at least 33 massive stars in the end stages of formation, and the clear presence of the complex carbon molecules known as polycyclic aromatic hydrocarbons (PAHs). PAHs are thought to be created in the cooling gas of star forming region s, and their development in the Sun's formation nebula five billion years ago may have been an important step in the development of life on Earth. ...
