Writing in Astronomy¤
Writing in astronomy will have some different workflows to other fields - in particular, almost every paper is written in the formatting language LaTeX, rather than (say) Word, and we have to use specialist tools to work with this. It has a bit of a steep learning curve but because it makes it so easy to format citations and equations, it's actually a really helpful part of the workflow.
Writing Papers¤
Knapen et al have an excellent paper on general advice for publishing in astronomy.
LaTeX Guides¤
There is a good LaTeX guide on astrobites.
Overleaf¤
People have strong views about LaTeX environments, but my preferred go-to for ease of use is Overleaf, which like Google Docs allows people to collaboratively work on the same document.
Writing for the Public¤
It is really important not just to learn to write papers - a lot of an astronomer's job is actually writing proposals, reviews, lectures, and public engagement material. It is a great idea to practise this! One good place to start is to pitch an idea to astrobites as a guest post. For a more substantial and public facing piece, you might like to pitch to The Conversation.
