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.

。它还为 Bluesky 应用程序打开了一个候补名单，该团队将其定为访问 AT 协议网络的理想“浏览器”。候补名单很快就被填满了，需要第三方干预。

B | Bluesky 团队在今天的博文中表示：“自今年 5 月以来，我们一直在 GitHub 上的公共存储库中改进协议，只是我们在博客和 Twitter 上大多保持安静。不过接下来这种情况会发生改变”。

C | AT 协议作为去中心化网络，独立于任何一家公司的意愿运作。Bluesky 认为，这种独立性将允许在协议之上构建的社交网络的用户既能保护他们的私人数据，又能避免经常引发争议以使用户着迷的公司算法。Bluesky 表示：“算法决定了我们所看到的以及我们可以接触到的人。如果我们要信任我们的在线空间，我们必须控制我们的算法”。
