Dear Nautilus reader,

With your help, we’ve had an amazing first two years: Two National Magazine Awards, a Webby for best science website, and more than a dozen other awards. Nearly 10 million readers through our website. Print subscribers in 40+ countries.

What a great start! But it’s just the beginning. There are many more stories to tell.

To help us tell them, we are changing the way we serve our content. Starting today, the first seven feature article reads of the month will be free, as usual. After that, our features will be restricted to Nautilus Prime members. It’s a strong value at just $19 for a whole year. And if you use the code prmsoc15, you can get it for just $12, until September 10. That’s just a buck a month. Or you can get a print subscription, which includes Prime for free.

Joining Nautilus Prime gets you free and unlimited reading of all of our content—plus free tablet editions of our print magazine, and free eBooks of all our issues. We even remove all the ads from our site when you’re logged in.

Our Facts So Romantic blog, and our Three Sentence Science news feed will be free for every reader and exempt of the monthly read limit. Same for any stories you share, or links that you follow from social media, top aggregators, and search.

We launched Nautilus with a generous grant from the John Templeton Foundation. As we have grown and increased our breadth of content, we have also broadened our support, to include the Simons Foundation and the Howard Hughes Medical Institute.

You, our reader, are an important part of our efforts to expand our support further. Whether it is through a Prime subscription, print subscription, or tax-deductible donation, you can help us expand the Nautilus brand of science journalism: independent, rigorous, thoughtful, and always placing readers first.
