西藏天文馆 Currently at the moment in Lhasa the region capital of Tibet Autonomous Region of China- People’s Republic of China the Construction of the world’s highest – The world’s highest-altitude planetarium, the西藏天文馆Tibet Planetarium, started construction in Lhasa on June 12. It is reported that the roof of the planetarium will be equipped with a refracting optical astronomical telescope with a diameter of 1.06 meters, which will also be the largest refracting optical astronomical telescope in the world. The planetarium has a total construction area of ​​11,571.9 square meters and is expected to be completed in June 2024. The roof of the planetarium will be equipped with a refracting optical telescope with a diameter of about 1.06 meters. This astronomical telescope will also surpass the 1.02-meter-diameter refractor telescope of the Yerkes Observatory in the United States and become the world’s largest refracting astronomical telescope. …


This one-meter-class refractor telescope can monitor variable stars, poor photometry of binary stars, and supernova monitoring. The scope of monitoring includes celestial bodies in the solar system, stars in the Milky Way, and even some nearby galaxies in the outer reaches of the Milky Way can also be observed.
In addition, in scientific research work, this one-meter-class refracting telescope will be used for space target observation, providing space early warning services for my country’s space launch activities and the on-orbit operation of spacecraft.


“Space debris and space junk are being monitored on a global scale, and this monitoring network requires a large number of space observation facilities such as telescopes to work together. The scientific goals of our one-meter-class refractor telescope also involve near-Earth detection in space. The monitoring activities of small celestial bodies and space debris are part of the entire monitoring network.” Wang Junjie said that there is no professional large-scale astronomical observation telescope in the vast Tibet area, and the space monitoring network needs to deploy monitoring equipment closely. The high-level refractor telescope is equivalent to filling the “blind area” of China’s space monitoring network. It will become an important part of the entire monitoring system. The monitoring data obtained will also be used together with the data of other monitoring facilities to calculate the space flight. The construction of the Tibet Planetarium in the orbit of the object　

The special geographical and climatic advantages of Tibet can also facilitate astronomical observations. In order to reduce the influence of atmospheric, weather and other factors on astronomical observation activities, astronomical observation facilities should preferably be located in places with higher altitudes, more sunshine and less rain, and less light pollution. The characteristics of high altitude, sunny days, low population density and high atmospheric visibility in Lhasa will be conducive to astronomical observations.

　　In addition, the Tibet Planetarium after its completion will also undertake a special mission, that is, to carry out astronomical science popularization activities that are easy for the public, especially young people to participate in and accept, and popularize astronomical science knowledge through exhibitions, training, experiments, video broadcasts, lectures, etc. , to spread scientific ideas.

　”The world’s highest-altitude planetarium, coupled with the world’s largest refracting optical astronomical telescope, will have a huge appeal to local people, domestic and foreign tourists, and astronomy enthusiasts. The scientific and cultural literacy of the public plays a unique and important role.” Wang Junjie said that he believed that the Tibet Planetarium would become a new local Internet celebrity landmark, attracting local people and global tourists to visit.

　　According to the operation data of the Tibet Natural Science Museum over the years, the annual reception of the Tibet Planetarium is expected to reach more than 100,000 people, and more than 100,000 people can receive astronomical science popularization education every year.

　　Wang Junjie said that in recent years, the astronomical undertakings in Tibet have been developing continuously, from the Tibet Yangbajing Observatory, the first professional observatory in Tibet, the National Astronomical Observatory, to the Ali Observatory of the National Astronomical Observatory in western Tibet. The former has a submillimeter-wave telescope in cooperation with Germany, which mainly explores star formation, organic molecules, etc. The latter is still under further construction, including gravitational wave telescopes, optical telescopes and other equipment.

During the week of 20th May 2022 In an announcement CNSA – China National Space Administration– Chinese Academy of Sciences will launch an optical telescope with a diameter of 1.2 meters to search for habitable exoplanets in the immediate vicinity] Chinese scientists have proposed a sky survey program through space telescopes to search for habitable terrestrial planets outside the solar system about 32 light-years away from the earth. If implemented, this will be the first international space exploration mission dedicated to finding habitable terrestrial planets around nearby sun-like stars.

Ji Jianghui, a researcher at the Purple Mountain Observatory of the Chinese Academy of Sciences and the project leader of the “Nearby-habitable Planetary Survey Program”, introduced that the “Nearby-habitable Planetary Survey Program” will observe about 100 sun-like stars about 32 light-years away from the earth for a long time, which is expected to be the first time. The discovery of habitable zone terrestrial planets around them, especially “Earth 2.0” (planets with a size, orbit and environment very similar to Earth), achieve a major breakthrough in “from 0 to 1”. It is estimated that this plan is expected to discover about 50 terrestrial planets. Scientists will give information such as the number, true mass and three-dimensional orbits of habitable planets and “super-Earths” (exoplanets several times to 10 times the mass of Earth) through a detailed census of the nearby planetary systems in the solar system.

According to the plan, a high image quality, low distortion, high stability optical telescope with an aperture of 1.2 meters will be sent into the Halo orbit of the second Lagrangian point of the Sun-Earth system, and will maintain stable operation in this orbit for at least 5 years Time, during which 100 sun-like stars will be scientifically detected, and each star will be observed no less than 50 times.

On 14th April 2022 China – People’s Republic of China has incredibility  has built a new generation of sky survey telescopes with a primary mirror diameter of 2.5 meters and 720 million pixels with Another Chinese Tianyan opened? Qinghai Lenghu will build a survey telescope with a primary mirror diameter of 2.5 meters….  Which If you use a lens with a diameter of 2.5 meters and a photosensitive element with 720 million pixels to make a telescope, how far can it see? How clear will things be?

​​

China – People’s Republic of China is currently manufacturing such a telescope. It is co-operated by the University of Science and Technology of China and the Haixi Mongolian and Tibetan Autonomous Prefecture of Qinghai Province. One of the sites of the astronomical observatory), the Wide Field Survey Telescope, whose full name is the University of Science and Technology of China – Purple Mountain Observatory of the Chinese Academy of Sciences Large Field Survey Telescope, English name Wide Field Survey Telescope, referred to as WFST, it is China – People’s Republic of China The new generation of astronomical survey telescopes developed by the State, a major national astronomical observation infrastructure, will become the optical time-domain survey telescope with the strongest ability to survey the sky in the northern hemisphere after completion.

​According to the news from the University of Science and Technology of China on April 11, the research and development team composed of the university and the Purple Mountain Observatory of the Chinese Academy of Sciences has completed the development of the primary mirror CCD290 camera and CCD test system. The relevant results have been published in the world famous astronomical instrument. In the publication “Journal of Astronomical Telescope Instruments and Systems”, this innovative research result laid the foundation for the development of the main focus camera for the large field telescope.

The large-field survey telescope is a new generation of astronomical telescopes developed in my country. The diameter of its main mirror is 2.5 meters. The design adopts the international leading main focus optical mode, which can provide a large field of view, high precision and wide-band sky survey capabilities. , its photosensitive element is a large area array 720 million pixel splicing CCD detector, which is spliced ​​by 9 CCD290-99 chips, the imaging array reaches 9K x 9K, and the imaging area reaches 92.2 mm × 92.4 mm, with ultra-low noise readout capability , the readout noise can be less than 5 electrons at a readout rate of 500Kpix/s.

​The main focus camera with

​Some people call the large-field survey telescope “another Chinese sky eye”. It is true that both have strong sky survey and observation capabilities, but the two are very different. In terms of observation methods, the Chinese sky eye (FAST) It does not move, basically just patrols the night sky with the rotation of the earth. It is impossible to fix the viewing angle at a certain point in the night for detailed observation, but WFST can dynamically patrol the night sky and can fix a certain celestial object on the sky. long time observation.

​As the strongest large-field optical survey telescope in the northern hemisphere, WFST is a “three-in-one” powerful prime focus camera that integrates “scientific imaging, wavefront detection, and guide star sensing”. It can discover countless galaxies, quasars and stars in the huge cosmic space, and can also monitor large-scale celestial collisions, supernova explosions, stellar helium flashes, fast radio bursts and other transient sources in distant cosmic spaces, as well as the Milky Way and nearby galaxies. Appearing variable stars and other celestial bodies, small celestial bodies such as asteroids and comets in the Kuiper belt in the solar system and far away can also be seen. In addition, the structure and formation and evolution history of galaxies can be judged by observing the star stream in the Milky Way and nearby galaxies.

Currently中国空间站 Previously On December 2021, the Belt and Road Initiative CNSA –China National Space Administration  CSS China Space Station in which on a three to six months setting up a new home of the first three Shenzhou 13 in which spending up to on for the further construction and verifications of the systems of the CSS –China Space Station 2021 launch calendar in which currently the three Takionauts current Shenzhou 13 ……  Preparations for the six months of extension of the China Space Station In which the currently it remains awaiting for the crew of setting up home in conducting fun scientifically onboard中国空间站..  China Space station ….. with among with more Shenzhou crew to arrive to finished construction of the China Space Station in which there’s more additional modules that could be detach and reattach itself as mission criteria required.  

Featuring the Sky Survey Optical Module has both sky and land survey capabilities, and can also be used as a remote sensing satellite] The Sky Survey Optical Module is equipped with a large telescope with a diameter of 2 meters. The observation wavelength range of the Sky Survey is 255~1000 nanometres, covering from, and visible light to near-infrared band. The optical module of the Sky Survey will not only fill the gap in my country’s space astronomical observation, but also achieve a resolution close to that of the Hubble Telescope and a field of view two orders of magnitude larger than that of the Hubble Telescope, and can quickly complete large-scale multicolour imaging and seamless spectral surveys. .

The superiority of the Sky Surveyor’s optical cabin is inseparable from its innovative design. In addition to a Cook-type off-axis three-reflection optical system with a diameter of 2 meters, the optical cabin also adds a folding mirror to facilitate switching between different optical loads, focusing, and precise image stabilization. The off-axis three-reflection is an excellent optical design. It is not only conducive to the realization of a large field of view, but also has no unavoidable optical path obstruction in the coaxial reflection optical system of the Hubble and Webb telescopes. Advantages, there is no diffraction problem caused by mirror support, and the optical imaging quality is higher. The Sky Survey Optical Module will also be the first space telescope in my country to use active optics. By actively adjusting the deformation of the secondary mirror, the imaging quality of the telescope can be further improved.

In addition, the optical module of Tian Xun can not only fly autonomously, but also has high attitude adjustment accuracy, and also has the ability to actively rendezvous and dock the space station. It can receive propellant replenishment while docked at the space station, and maintain, repair and upgrade equipment. Compared with the Hubble Space Shuttle that needs to be launched for every maintenance, the co-orbit flight of the Sky Surveyor’s optical module and the orbit maintenance design of the space station have better maintenance efficiency and cost-effectiveness.

In addition, the optical cabin also has the ability to survey the sky and land, and can be used as a remote sensing satellite. This design concept is a world first.

According to the plan, the optical module and the space station will fly in the same orbit, which is mainly used for astronomical observation, taking into account the ability to observe the earth. It can provide a sky survey observation capability with a resolution roughly equivalent to that of the Hubble telescope but with a field of view more than 300 times larger. The performance of the optical system is also one of the few in the world’s new generation of space telescopes. In addition, the sensor of the optical module is also remarkable. It is equipped with five payloads, including a sky survey camera, an integral field of view spectrometer, a multi-channel imager, an exoplanet imaging coronagraph, and a terahertz receiver. In addition to the fast survey capabilities of the exoplanet imaging coronagraph, it also adds the ability to detect and study exoplanets.

The main task of the optical module of the Sky Survey is to survey the sky. The researchers plan to conduct multi-color imaging observations of 17,500 square degrees, as well as seamless spectral observations in the same sky area, as well as 400 square degrees of multi-color imaging deep-field observations. and seamless spectral deep-field observations in the same sky region.

In addition, it will also study the formation and evolution of cosmic celestial bodies through observations of galaxies and active galactic nuclei, as well as nearby universes and stars. It can also be used to observe a large number of faint and small celestial bodies in the solar system, as well as observe and study transient sources. In the next 10 years of sky survey and observation missions, the sky survey optical module is expected to rely on its excellent performance to observe and analyze and reveal the mechanism of the accelerated expansion of the universe, and even bring unexpected major scientific discoveries.
