Chinese-made infrared telescope with domestic detectors achieves astronomical imaging, reducing foreign reliance_我的网站

Chinese scientists on Wednesday released the first complete set of observational images captured by China's new-generation ground-based infrared telescope, filling a gap in the country's near-infrared astronomical observation capabilities and reducing reliance on foreign infrared detector technology, China News Service reported on Wednesday.
The 80-centimeter near-infrared telescope was installed at Saishiteng Mountain, Lenghu township, Northwest China's Qinghai Province in October 2024. Jointly developed by Sun Yat-sen University and several partner institutions, the telescope is China's first to achieve scientific imaging in the 1.2-micrometer J band and 2.2-micrometer K band using domestically developed scientific-grade InGaAs and HgCdTe detectors.
The telescope enables unattended remote operations, and can lock onto any target in the sky within 15 seconds. Its infrared capability allows it to see through interstellar dust, enabling it to observe cold and distant celestial objects that are difficult for optical telescopes to capture.
According to Ma Bin, a professor at the School of Physics and Astronomy, Sun Yat-sen University who led the research team that released the infrared telescope's observational images, all three of the telescope's core astronomical observation capabilities were fully validated during operation.
It rapidly responded to and tracked multiple gamma-ray bursts and supernova events, recording the evolution of their infrared afterglows following the explosions. It continuously monitored brown dwarfs, precisely capturing periodic variations in their atmospheric brightness. Using image-stacking technology, it also observed active galaxies billions of light-years away.
Since its deployment in Lenghu, the system has supported infrared observations for more than 10 Chinese research institutions, accumulating valuable experience for the construction of future large-scale infrared telescopes.
Lenghu township, where the world-class astronomical observation base takes shape, is hailed as "the most Mars-like place on the Earth." The astronomical observation base was said to be an astronomical observation site comparable to the top ones in the world by a Nature article published on August 18, 2021, according to the Chinese Academy of Sciences.
Once prospered in 1950s due to its rich petroleum resources, Lenghu is now becoming a premier astronomical observation site and Mars-themed tourist destination, according to Xinhua News Agency.

二 | 1月16日，美足创始人、董事长兼首席执行官黄章昨晚在微博上宣布了秋龙855的三款车型：美足16S、美足16S Plus和美足16G，其中美足16S为6.2英寸，16S P为6.5英寸。它们都是Myulong 855的旗舰。以较低的价格出售给Meizu游戏的16G手机并不是旗舰产品，而是以较低的价格出售给游戏的855手机。此外，它的电池容量是4000-4500mAh，这延续了第16次无爆炸设计，有一个更窄的下巴和下巴。然而，由于对美足16G的“G”的误解，黄章最终改名为美足16G，虽然“G”的意思是“游戏”。今天，黄章在昨天的投票中写道：“如果游戏手机的名字很容易被误解，那就叫16T（turbo）。”他正式改名为16G的美祖16T，并将“T”标记为“turbo”。除了这些手机外，黄章此前还确认了Meizu Note9正在研发中，将搭载4800万像素和最新的6150处理器Miaolong。
