What is a Astronomer?

An astronomer studies stars, planets, galaxies, and other objects in space. They use telescopes, sensors, and software to collect data and test ideas about the universe. Most Australian astronomers work at universities, CSIRO, or research sites around the country.

In practice, most astronomers spend little time at a telescope. Most of their work is done on a computer. They write code, build models of space events, and read through large data sets. This makes coding skills as vital as maths and physics.

Working with others is central to the role. Astronomers team up with colleagues at other sites, often in other countries. Many also teach students, run outreach events, and take part in public science programs.

The career rewards curiosity and persistence. Australia plays a major role in world astronomy. Key bodies include CSIRO and the Square Kilometre Array (SKA) project. This gives Australian astronomers access to world-class tools and research teams.

Career snapshots For Astronomers

Astronomers in Australia work mainly in the education and research sectors. Most are employed at universities or through government bodies like CSIRO. The role falls under ANZSCO 2512 (Physicists and Astronomers) in the Australian system.

The average annual salary for an Australian astronomer is around $92,500 (PayScale, 2025). Salaries range from about $70,000 for early-career researchers to over $115,000 for senior academics. Most positions are full-time, with a standard 38 to 40 hour week. Observation trips can add extra hours.

Australia’s role in the Square Kilometre Array (SKA) signals ongoing demand for skilled researchers. CSIRO Astronomy and Space Science is also investing in the field. Data skills from astronomy also transfer well to careers in technology, finance, and data science.

What will I do?

Astronomers research the universe using telescopes, satellites, and computers. Their work covers watching, data work, and theory testing. Each day can bring a new task, from writing a grant proposal to presenting at a conference.

  • Use telescopes and sensors to watch objects and events in space
  • Process and study big data sets using Python and analysis tools
  • Build computer models of events in space
  • Write and submit research papers to scientific journals
  • Apply for grants to fund research projects
  • Work with research teams in Australia and overseas
  • Present findings at conferences and public events
  • Teach and mentor students at university

What skills do I need?

A career as an astronomer demands strong skills in maths and physics. These subjects form the base of all research work, from building models to reading telescope data. Most astronomers build these skills through a science degree and then a PhD.

Coding is just as important as science knowledge. Python is widely used for data work and models. Experience with Unix and Linux systems is also common in research settings. The ability to work with large, complex data sets is one of the most valued skills in the field.

Good communication rounds out the skill set. Astronomers write research papers, present at conferences, and often talk to the public. Critical thinking and attention to detail are vital. So is the patience to work on long-term projects.
