Who is a Cosmologist?

First things first, let us properly understand who a Cosmologist is. Cosmologists are the scientists who study the properties of space using telescopes and satellites. They are not involved in practical data collection but rather interpret the data that we intercept from satellites etc to give theories on planets, black holes and galaxies by observing their behaviour over the years. They calculate distances and make observations on the size, motion and brightness of the various celestial objects in space. 

Did you know? String Theory suggests that our universe is made up of tiny vibrating strings which are smaller than the subatomic particles! Gabriele Veneziano gave birth to this theory while trying to explain the strong interaction. 

Duties of a Cosmologist

Here are some of the roles and responsibilities of a Cosmologist. 

  • They design instruments like lasers and telescopes.
  • Then use such instruments to observe astronomical events and celestial objects
  • Moreover, cosmologists also design various computer programs to analyze the data.
  • They also test the theories of the formation of the universe. 
  • Presenting the research and recent breakthroughs at conferences also comes under their responsibility. 
  • Lastly, they also analyse data using complex mathematical functions and equations.

This step will also immensely help you in building connections with veteran researchers and building a name for yourself by presenting your research at various places. This majorly increases your chances of getting hired.  


The next step is to decide where you want to put your expertise as a cosmologist. If you wish to be a university professor, then this is the right time to apply. However, if you wish to work at a related company, you should still take up a postdoctoral research position or a fellowship. Although you can also directly apply to cosmologist positions at this point, however, some companies require you to have a certain amount of experience which is why going through a fellowship is a better option. You will be working in an environment where you can gain experience, skills as well expert guidance.
