    The study of stars and stellar evolution is fundamental to our understanding of the Universe. The astrophysics of stars has been determined through observation and theoretical understanding; and from computer simulations of the interior. [99] Star formation occurs in dense regions of dust and gas, known as giant molecular clouds.
