. The Digital Universe Atlas has spun off a commercial-grade planetarium platform from SCISS called Uniview that was featured in the White House star party on October 7, 2009. The Atlas database and Partiview interface is compatible with professional planetarium software such as Evans & Sutherland's Digistar and Sky-Skan's DigitalSky 2. The Digital Universe is now a critical component of the OpenSpace open source interactive data visualization software suite. In 2014, a NASA grant (supported by the NASA Science Mission Directorate in response to NASA Cooperative Agreement Number (CAN) NNH15ZDA004C, Amendment 1) was awarded to the American Museum of Natural History for the development of the OpenSpace project, to utilize the latest data visualization techniques and graphics card technologies for rapid data throughput. OpenSpace and its Digital Universe datasets work on all operating systems and is available for free download.
