As an astronomer, used a wide range of scientific techniques to study the universe, its origin and composition. You could specialize in one area such as planetary science, solar astronomy, the origin and evolution of stars or the formation of galaxies.
Astronomy can be divided into two main areas - the astronomical observations and theoretical astronomy.

The astronomical observation
In this area, their work could include:
· The development of new instrumentation and maintenance of existing equipment
• Using optical and radio telescopes or computers to satellites and spacecraft to collect data
· Software development for interpreting the images obtained from satellites
• Analyze the data and test theories.
Theoretical Astronomy
His work in this area involve:
· The creation of complex computer models to develop theories about the physical processes occurring in space
• Analyze the results of past observations to develop new predictions (hypotheses)
· Make observations and test theories
· The results of analysis in relation to what is known (this could lead to advances in knowledge about events in the universe).
