From Astrophysics to Data Science


Visualising the career paths of 200 astronomers turned data scientists.

The first in a series of blog posts that explore why astronomers are leaving academia.


The Science to Data Science (S2DS) and Insight Data Science fellowships are 5–7 week intensive post-doctoral training fellowships that bridge the gap between academia and data science in industry. This interactive visualisation was created to get a better sense of what stage in their career astronomers move into data science.

  • How many PhD students forego postdoctoral research in favour of moving straight into data science?

  • How many professional astronomers are moving into data science?

  • At what stage of their career do they do this?

  • How may postdocs do they have on their CV before deciding to leave?

  • Are tenured astronomers moving into data science?

  • How many go through a data science fellowship programs?

  • How many do industry internships?

  • How many go back to complete a Masters in Data Science or other similarly formal data science education?

  • How many make the transition without a data science fellowship? Have any moved back and forth between academia and data science? </p>

  • Why do they move in data science?

The data: comes from the LinkedIn profiles of 116 astronomers who moved from astronomy to data science at some point in their career.

The visualisation: was created using the d3.js sunburst template, HTML, and CSS.
