Exciting change is on the way! Please join us at nsf.gov for the latest news on NSF-funded research. While the NSF Science360 page and daily newsletter have now been retired, there’s much happening at nsf.gov. You’ll find current research news on the homepage and much more to explore throughout the site. Best of all, we’ve begun to build a brand-new website that will bring together news, social media, multimedia and more in a way that offers visitors a rich, rewarding, user-friendly experience.

Want to continue to receive email updates on the latest NSF research news and multimedia content? On September 23rd we’ll begin sending those updates via GovDelivery. If you’d prefer not to receive them, please unsubscribe now from Science360 News and your email address will not be moved into the new system.

Thanks so much for being part of the NSF Science360 News Service community. We hope you’ll stay with us during this transition so that we can continue to share the many ways NSF-funded research is advancing knowledge that transforms our future.

Creating an augmented-reality sandbox for astrophysics

Undergraduate students designed and built a sandbox where users can mold their own universe with sand and watch how gravity affects an object -- a spacecraft or a comet, for example -- as it travels through the imagined environment. Funded by a grant from the National Science Foundation, the augmented-reality sandbox, dubbed "Gravbox," is the first interactive system of its kind to be used for astrophysics. Similar setups exist for geology and engineering but the student researchers advanced the concept to bring gravity, an invisible force not easily explained or understood, to life. The sandbox will be used to teach fundamental principles in physics, such as gravitational dynamics involved in the distribution of stars, the shapes and evolution of galaxies, and more.
