What are the objects in the planetarium?

Beijing Planetarium includes two pavilions A and B and four popular science theaters. In Hall A, there is a Foucault pendulum reflecting the rotation of the earth in the center, an astronomical knowledge exhibition in the west exhibition hall, and academic exchanges and reports on astronomical popular science knowledge are often held in the East lecture hall. There are two observatories in the yard, one of which is equipped with a telescope with a diameter of 13 cm, through which you can watch the moon, planets, nebulae and clusters, and observe sunspots during the day. The other is the chromosphere Telescope Observatory, which uses the chromosphere telescope to observe and photograph the changes of the solar chromosphere. There is also an astronomical square on the west side to display outdoor observation instruments.

The planetarium located in Hall A is the largest horizontal planetarium in Chinese mainland, and its internal equipment is at the leading level in the world. Among them, Zeiss -9 optical planetarium and the world's highest resolution all-sky digital projection system can not only realistically restore more than 9,000 stars visible to the naked eye on the earth, but also realize virtual sky demonstration, three-dimensional space simulation, digital program playback and other functions for 400 spectators in the venue.

As the largest horizon sky hall in Chinese mainland, the dome has an inner diameter of 23 meters, and its interior is divided into four areas: red, green, brown and blue, to ensure that every audience has a good viewing angle. The world's first 13. 1 stereo surround sound system can make every audience experience a unique surround sound effect.

Hall B (new hall) was officially completed and opened at the end of 2004. There are three popular science theaters: Cosmic Theater, 4D Theater and 3D Theater, as well as various popular science education facilities such as Astronomical Exhibition Hall, Solar Observatory, Public Observatory and Astronomical Classroom. Among them, the Cosmic Theater with a radius of18m has a standard hemispherical canopy, which can present a three-dimensional canopy effect for 200 spectators at the same time. Pavilion B designed by China Aerospace Architectural Design and Research Institute is surrounded by distorted "spatial texture" (this phenomenon is explained by Einstein's theory of relativity that massive celestial bodies force small celestial bodies to distort and attract small celestial bodies to fall). In the new museum, key spaces such as space theater and dynamic cinema are placed in the middle of the huge violin-shaped string, just like the basic particles produced in the vibration of the string. Based on its superstring theory, the relationship between gravity and elementary particles is explained (the theory holds that elementary particles of matter are produced when strings with extremely small diameters vibrate).

Cosmic Theater is the first Cosmic Theater with a three-dimensional spherical curtain in Chinese mainland. A standard hemisphere with a radius of 18m and an inclination of 15 degrees is equipped with an all-aluminum metal ball curtain made in the United States as the whole sky curtain. The cinema plays ultra-high resolution and delicate pictures with high immersion display technology, and the 3D effect is excellent.

4D Theatre is located on the second floor of Hall B of Beijing Planetarium. The whole theater can accommodate 200 spectators at the same time. Audiences should wear special polarized stereoscopic glasses when watching movies. According to the development of the movie plot, special effects equipment will produce special effects such as water spray, wind spray, lightning, backstab, ball, ear wind and leg slapping.

The 3D Cinema is located on the ground floor of Hall B of the Beijing Planetarium, with 1 16 seats, a screen width of12m and a height of 9m. It is a stepped small giant screen cinema. The cinema adopts advanced playback equipment and introduces 4K high-definition popular science programs, and the picture effect is real and clear.

Besides, the Beijing Ancient Observatory outside Jianguomen is also managed by the Beijing Planetarium, which is the ancient royal observatory of China.
