MojoKid writes "The Adler Planetarium has finished a major two-year upgrade project that's replaced the facility's forty year-old Zeiss Mark VI projector with a 'Digital Starball' system designed by Global Immersion Ltd. The new digital system is powered by an array of NVIDIA Quadro GPUs. The specs behind the system are impressive. The 71-foot dome of the Grainger Sky Theater now contains a score of military-grade projectors with an 8kx8k resolution. The final 64 megapixel image is generated by an array of 42 NVIDIA Quadro GPUs and offers an unprecedented degree of real-time modeling horsepower. The planetarium's model of the universe was created in part from high-definition photos captured around the world and via the Hubble telescope."
