I’m an award-winning astronomy author, writer and speaker who has talked to over half a million people about the universe, including schools, the public and businesses. My seventeen books have sold more than 350,000 copies worldwide and been translated into 21 languages. I’ve written over 200 popular science articles for publications including The Guardian, New Scientist, The Wall Street Journal and European Space Agency.


In recognition of my efforts to popularise astronomy, the asteroid (15347) Colinstuart is named after me. I won The Margaret Mallett Award for Children’s Non-Fiction in 2020 and have been runner-up in the European Astronomy Journalism Prize. A fellow of the Royal Astronomical Society, I’ve talked about space on Sky News, BBC News and Radio 5Live.

Popular science writing course - how to be a science writer

I run a one-day, online popular science writing course. Unlike other courses heavy on theory, there’s a strong focus on practical steps to get you paid writing work. I’ll take you through examples of successful pitches and show you how to write a non-fiction book proposal.

“More than worth the cost of the course 10 times over… I left the workshop with a head bursting with ideas and I am really excited to see how this develops for me”
