Beyond the Printed Page

You’ll find here the digital extras that accompany our feature articles, including interviews with world-renowned experts, simulations of the newest astronomical theories, and extensive image galleries. Go beyond the printed page to explore the multimedia world of science discovery and community interaction.

Don’t know where to start? Here are some suggestions: After reading about the role of citizen science in astronomy in the March 2014 cover story, check out Meg Lamb’s online article about two of the newest Zooniverse programs looking for your participation: Space Warps and Planet Four. Or watch simulations of the unfolding universe that accompanied Joel Primack’s July 2012 cover story on the newest cosmology results. And don’t miss editor in chief Robert Naeye’s exclusive interview with exoplanet expert and MacArthur “Genius Grant” recipient Sara Seager (MIT).
