This content is provided in languages:

According to NASA, more than 2.250 artificial satellites are in orbit around Earth . The signals of these satellites are not only used by a vast array of professionals (scientists, mechanical engineers), but also find numerous applications in everyday life (GPS-telecommunications). Satellite science contributes to the improvement of the quality of our life, and shall continue to further advance science and space exploration.

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%.
