An astronomer studies celestial objects and phenomena, often spending far more time analyzing data from telescopes and surveys than looking through a telescope directly. A typical day includes writing code to process astronomical data, running simulations, and working through the math behind a specific research question.

Most professional astronomy positions are research- and academia-focused, requiring a PhD, and involve significant time writing papers and grant proposals in addition to the scientific work itself.

Core tasks

  • Analyzing data from telescopes or astronomical surveys
  • Running simulations and theoretical models
  • Writing code to process large datasets
  • Writing research papers and grant proposals
  • Presenting findings at conferences
  • Collaborating with international research teams

Typical entry paths

  • Astronomy or Physics, followed by a PhD for research-focused positions

Common misconceptions

  • The job involves far more computational data analysis than looking through telescopes directly.
  • Nearly all professional research positions require a PhD, a bachelor's degree alone typically leads to technician or support roles rather than independent research.
