Earth and Space Science

While Earth and space have been studied independently for centuries, the discipline of Earth and Space Science developed around 1919. In that time, the field has contributed tremendous advances to our knowledge and understanding of the universe, the formation of the solar system and how the Earth came to be. Through scientific observation and experimentation, researchers in the field work to understand processes that act on the bodies and features of space, such as gravitation, electromagnetism and star formation. This branch of science also describes and analyses the systems associated with the Earth, planets and stars, the chemical elements and resources associated with these celestial bodies, and their geological structure and history.
