They also discovered binary stars and showed that they revolve around each other. To explain his discoveries Herschel developed a theory of cosmogony based on the principle of evolution. In 1785 he proposed that all stars were originally evenly distributed and gradually pulled into galaxies by gravitational forces.

Who was the first person on Neptune?
