China to build world’s highest planetarium in Tibet

China to build

China will begin construction of the world’s highest planetarium next year in Tibet, which is often dubbed “Roof of the World”, being 4,000 metres above sea level. Planned to be completed in 2019, the planetarium in Tibetan capital Lhasa would benefit from clear skies due to the altitude and have the region’s largest optical astronomical telescope with a 1-metre-diameter lens.
