China built a giant solar telescope

Chinese scientists are looking for an area to build giant solar telescopes. It is expected that this will be the largest telescope in the world in the next 20 years, used to observe solar activities.

Under the plan, the national project to develop this giant telescope lasts for 10-15 years, has a total budget of about US $ 90 million and has been proposed by the entire solar energy community of China. . If the Chinese giant solar telescope project (CGST) is approved in early 2016, this will be the next generation of the solar telescope currently on the ground.

The project aims to build a very large infrared and solar photovoltaic telescope, with a spatial resolution expected to be equivalent to an 8 meter diameter telescope that collects light and energy equivalent. equivalent to a 5-meter-wide telescope. CGST will be able to accurately measure the magnetic field of solar energy with high resolution and detect the structure of solar fields as well as other energy classes of the planet. What during the last 100 years many important mysteries in solar physics have yet to be discovered.

If CGST of China is approved, it will pass all
Other solar telescopes on the ground are available.

Chinese scientists believe that CGST will surpass the capabilities of giant optical telescopes being projected by other countries, such as the advanced technology Solar Telescope (ATST). in Hawaii, or the European Solar Telescope (EST). Both telescopes have a 4 meter diameter design.

Previously in 2010, Chinese scientists carried out a four-year project to survey the region of the western solar observatory, funded by the China National Science Foundation, to Find out the best area to book CGST and other solar projects. It is possible that the western region such as Tibet Autonomous Region or Yunnan and Sichuan provinces may be the ideal area to place CGST.

Previously, in November 2010, although the CGST project was selected as a project in the 14-15 th 5-year Astronomy Development Plan (Period 2021-2025 and 2026-2030). However, the current CGST project is in the stage of waiting for approval. Meanwhile, a number of large-scale Chinese astronomical projects such as the sky-observation multi-object optical telescope (LAMOST was completed in 2008 in Xinglong, Hebei province, north) China, and the 500-meter Telescope Radio Area (FAST) will be completed in 2016 at Pingtang Southwest District of Guizhou Province.

In addition, China also plans to implement a solar space telescope (SST) project, which was proposed in the mid-1990s. This telescope has a diameter of 1 meter, equipped with a The extremely accurate and high-precision 2-dimensional spectrophotometer will be launched into space to observe the basic structure of the solar areas. With a diameter of 1 meter, China's SST will also exceed Japan's Japan's 0.5 meter Space Telescope designed in 2006.

It is known that the world's largest terrestrial solar telescope is a 1 meter diameter solar telescope in Sweden. At the same time countries like Germany are planning to develop a 1.5-meter-long solar telescope and the United States will soon deploy a 1.6-meter-long solar telescope.
