You may have heard that Zooniverse founder Chris Lintott has a book coming out later this month, exploring the history of the project and the fascinating discoveries our awesome volunteers have helped to make since its inception. To celebrate, we’re giving away ten signed copies of The Crowd and the Cosmos: Adventures in the Zooniverse!

All you have to do to be in with a chance of winning one of the books is to log in and submit at least one classification on any Zooniverse project this week, from Monday 21 October to Sunday 27 October 2019; we’ll then select the ten winners at random and get in touch to arrange delivery.
