Core Insights - The WeHoST project aims to enhance solar observation capabilities, focusing on understanding solar eruptions and their effects on Earth [1][2] - The telescope will be the largest axial symmetric solar telescope globally, with a significant increase in both field of view and resolution compared to existing telescopes [2][3] Group 1: Telescope Features - WeHoST will have a field of view expanded to 7 arcminutes, allowing observation of solar activities over a diameter of 300,000 kilometers, which is 3 to 4 times larger than current telescopes [2] - The resolution of WeHoST will reach between 0.1 to 0.3 arcseconds, enabling detailed observation of solar surface structures within 70 to 200 kilometers, improving resolution by 3 to 5 times compared to existing medium and small solar telescopes [2][4] Group 2: Technological Innovations - The telescope will utilize advanced cooling techniques to manage the heat generated by solar radiation, which can reach approximately 5000 watts on the mirror surface [3][4] - A self-adaptive optical technology will be employed to mitigate atmospheric disturbances, further enhancing image quality and resolution [4] Group 3: Integration with Existing Systems - WeHoST will complement existing solar observation satellites, such as the "Xihe" and "KuaFu-1," by providing larger and longer-lasting observational capabilities [3] - The project allows for future upgrades and integration with a comprehensive solar observation network, enhancing the overall understanding of solar phenomena [3]

Core Insights - The WeHoST project, a 2.5-meter large field high-resolution solar telescope, is set to enhance solar observation capabilities in China, with completion expected by the end of 2026 [1][2]. Group 1: Telescope Specifications - WeHoST will be the world's largest axially symmetric solar telescope, featuring a primary mirror diameter of 2.5 meters, which allows for both high resolution and a wide field of view, covering the entire solar activity area [2]. - The telescope's observational capabilities will be significantly improved, with a field of view expanded by three to four times compared to existing large solar telescopes [2]. Group 2: Scientific Collaboration and Objectives - WeHoST will work in conjunction with China's first solar exploration satellite, "Xihe," to enhance space weather monitoring and forecasting capabilities through a coordinated observation system [2][3]. - The telescope aims to provide comprehensive observations of solar phenomena, such as solar flares and coronal mass ejections, which can impact space weather and technological systems on Earth [3]. Group 3: Technical Challenges and Solutions - A major technical challenge for the telescope is managing the heat generated by solar radiation, which can reach up to 5000 watts on the primary mirror [5]. - To address this, the design includes over 200 air tubes to dissipate heat and maintain temperature differentials within specified limits, ensuring stable operation [5]. Group 4: Operational Flexibility - WeHoST is designed to switch between day and night operations quickly, allowing it to observe transient astronomical events, thus contributing to the emerging field of time-domain astronomy [7]. - This capability positions WeHoST to play a significant role in global astronomical networks, enhancing the understanding of rapidly changing celestial phenomena [7].
