Cosmos https://cosmosmagazine.com/ has been a national quarterly magazine on general science published by The Royal Institution of Australia Inc (RiAus), a science communications organisation based in Adelaide.
In May 2025, the following message was sent to subscribers:
“After a review of its magazine business, CSIRO Publishing, the national science agency’s editorially independent publishing arm, has made the difficult decision to stop the production of Cosmos Magazine. The final print edition of Cosmos Magazine will be published in June 2025. Digital subscriptions will also end in June 2025.
A bright future
The Cosmos online news service will continue at cosmosmagazine.com but will transition later in the year to CSIRO Publishing’s new digital destination for science content. The new website will publish peer reviewed journals, e-books and fact-based science news to bring together our audiences for a sustainable future. A news team will be employed to continue publishing stories about the latest science discoveries as well as interviews with scientists.
Make sure you are signed up to Cosmos newsletters and keep up to date with those developments.
This decision was not made lightly and mirrors a wider shift of audiences away from print magazines and the rising costs of producing print magazines.
We wish to thank all the writers, staff and readers that have supported Cosmos magazine over so many years.
If you have any enquiries about … the future of Cosmos please contact us on publishing.sales@csiro.au or 1300 788000.”
