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.

。北京时间8月21日晚，针对3名申花球迷围攻辱骂一位身穿国足7号球衣的男童父亲一事，中足联官方发布处罚公告，对申花主场予以通报批评。

二 | 而在因为自家3名球迷辱骂男童父亲遭通报批评后，申花官方第一时间发布声明，表示完全接受中足联的处理决定，并承诺将进一步完善主场赛事运营管理，持续优化入场观赛各项服务，提升广大球迷的观赛体验。此外，申花俱乐部还呼吁球迷理性呐喊。并表示俱乐部正处于新教练团队接手后的转型期，希望广大申花球迷予以包容理解，新的教练组。

三 | 而申花的公告并没有得到球迷买账，不少申花球迷纷纷涌入该声明的评论区，怒批俱乐部：“太怂了吧？干脆降级算了！”；“这个声明要表达什么？说了等于没说！”；“没有一点铁血气势！”；“让我们守底线，别人都没底线来挑衅，你让我们守住底线？”；“无能久事！还我申花！” 在本周中中超第18轮补赛，上海申花主场0-3不敌北京国安，赛后一名身穿武磊国家队7号球衣的小球迷与其父亲，遭到部分球迷围攻，3名申花球迷因寻衅滋事的违法行为被行政拘留。
