It contributes to technology, our economy and wider society by constantly pushing for better instruments and processes. Observations are used to evaluate and confirm theoretical models (which are representations that describe things that cannot be experienced directly).Īstronomy changes our world view and pursues questions fundamental to human existence. Theoretical astronomers use the data gathered through observations to create simulations. Observational and theoretical astronomers often work together to overcome this restricted view of the universe. For example, the sun is only halfway through its 10 billion year life. So, we can only observe snapshots in time of these things. Theoretical astronomy models and analyses how space systems may have evolved.Īstronomy is a long game as astronomers try to understand things in the universe that may be billions of years old. Observational astronomy gathers and analyses information. This includes the sun, planets, moons, stars, galaxies, gas, dust and everything in between.Īstronomy is now split into two fields: observational and theoretical. Astronomy is the study of everything in space.
