LESSON 1: OUR VIEWS ABOUT THE COSMOS Creative Commons, Attribution + Noncommercial + ShareAlike (BY-NC-SA)
This content is provided in languages:

Since Antiquity humans sought to interpret and predict the celestial phenomena, a process that gradually led to the creation of descriptive models about the structure of the Cosmos. The geocentric point of view that predominated during the ancient era and up to the Middle Ages, was the main pillar for the interpretation of the astronomical observations. The shift to the heliocentric view constituted a decisive step towards the modern understanding of the structure and function of Nature.

Workforce in Astronomy

Around 540,000 students study astronomy, physics, chemistry, and earth science in the EU. Besides astronomer or astrophysicist, there are many jobs available for which an astronomy degree is valuable. They include aerospace engineer, climatologist, computer systems analyst, data analyst, engineer, geophysicist, instrument designer, planetarium director, programmer, physicist, research scientist, science writer/journalist, software developer, statistician, teacher or professor, telescope operator. Jobs for scientists and engineers grew by 7% in the past five years. Jobs for technicians in the field grew by 2%. Overall, they account for 7% of all jobs in the EU. As of 2016, around 15 million European science and engineering workers are employed. They work in a variety of sectors, including professional services, utilities, manufacturing, and the public sector. In the next years, jobs for engineers and researchers will increase by 13%, and jobs for science and engineering technicians will increase by 2%.
