Hello, I'm DVdm. I noticed that you made a change to an article, Carl Sagan, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. DVdm (talk) 08:45, 23 October 2016 (UTC)
