Way back before io9.gizmodo.com was a url, io9 covered science just as much as science fiction. When Annalee Newitz founded the site in 2008, she wanted it to focus on both as they increasingly intersected, and on how they could both lead culture—pop and otherwise—into the future.
Of course, no one truly knows what the future will bring. Annalee was made Editor-in-Chief of Gizmodo back in January 2015, making it all but inevitable that io9's science and space coverage would be consolidated with them, as we continued to cover nerd culture’s increasing dominance of pop. The process was complete when we became io9.gizmodo.com in December of that year.
But we would be remiss in our celebration of io9's first 10 years if we ignored this long and crucial part of the site’s make-up. So here are the 50 most popular articles (beginning with the most popular post) that have everything to do with science, history, nature, space, and so forth, and nothing to do with pop culture. Infinite thanks to writers like George Dvorksy, Robbie Gonzalez, Esther Inglis-Arkell, and all the other science writers who toiled at io9—most especially Annalee herself.
