Shanghai Planetarium (Shanghai Science and Technology Museum Branch), located in Dishui Lake, Lingang New District, Pudong New Area, Shanghai, started construction on 201year1October 8, and officially opened on July 7, 20021year. It is invested by Shanghai Municipal Government and integrates education, research, collection, display and interaction.
architectural design
The design of Shanghai Planetarium expresses astronomical concepts such as celestial bodies and orbital motion in architectural language. The design of the venue is inspired by the "three-body problem" in physics, focusing on the intricate trajectory of celestial bodies in the solar system caused by gravity. In the design of architectural modeling, the overall layout, internal space and visit streamline, trajectory, sphere, curve and suspension are all used.
Concrete and steel structure adopt irregular shapes, and the structural shapes are mostly irregular and multi-curved, and straight lines or right angles are abandoned to reflect the geometric shape of the universe and the dynamic energy of celestial movement. The main building consists of two overlapping ellipses. As three "celestial bodies" in architecture, there is a dynamic orbital relationship among circular skylight, inverted dome and sphere, which makes architecture an astronomical instrument that can display time through the change of the sun's light shadow.
Architectural design also highlights the theme of astronomical galaxies with the help of the connection with urban ecology. The outer periphery of the planetarium is widely designed in an arc shape. The landscape area outside the main building is introduced with spiral greening and trails, which naturally extend outward and form an organic connection with the "starry sky" park outside, symbolizing the spiral arm of the Milky Way. The ratio of sphere to drip lake in the planetarium is intentionally adjusted to reflect the relationship between the earth and the sun.
