About this 3D model

Model of the Hubble Space Telescope, which orbits the earth and has helped astronomers determine the age of the universe, the identity of quasars, and the existence of dark energy. For more information on Hubble and astronomy, see the free iBook [Reach for the Stars: Touch, Look, Listen, Learn](https://itunes.apple.com/us/book/reach-for-stars-touch-look/id763516126?mt=11). Produced by a collaboration between the [Space Telescope Science Institute](http://www.stsci.edu/) and [SAS](http:www.sas.com), both this model and the book are designed to expose all students—including those with visual impairments and other print disabilities—to critical STEM content. Additional information for students and teachers is also available for free at [SAS Curriculum Pathways](http://www.sascurriculumpathways.com/portal/).
