The Sun is the only star which in reality affects our life. In antiquity it was worshiped as a deity. The surface of the Sun is not stable, but changes continuously. The light from the Sun is composed by colours, which we can observe by using special devices. The energy from the Sun warms and lightens the Earth and the other planets.

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%.
