The Nebular Hypothesis

According to Pierre Simon Laplace's widely accepted nebular hypothesis, a star forms when gravity draws interstellar dust and hydrogen gas into an increasingly dense, small cloud that flattens into a rotating disc with most of its mass pulled to the center. If solar systems form from such discs, then there must be many in our own galaxy. The Hubble Space Telescope has produced dramatic images of star-forming regions in nearby space.
