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 |     外媒预计，接下来的几个月里，将有成千上万的球迷奔赴当地，以亲身感受世界杯的现场氛围、而不是蹲坐在屏幕面前收看视频直播。但是卡塔尔当局“要求”游客下载的应用程序 ——《Ehteraz》和《Hayya》—— 还是让网络安全研究人员感到无比担忧。包括挪威国家广播公司（NRK）安全主管 Øyvind Vasaasen 和 Bruce Schneier 在内的许多安全研究人员，都将其视作间谍软件。因为它会向用户索取向卡塔尔国家安全局提供的访问权限，以读取、编辑或删除用户手机上的任何信息。虽然 Øyvind Vasaasen 不会向大家提供旅行建议，但就个人感受而言，他是宁可不带手机去卡塔尔的。首先，《Ehteraz》是一款有 Android / iOS 客户端的 COVID-19 追踪 App —— 问题在于它索取的权限，远远超出了规范。一方面，该应用程序试图通过 Wi-Fi 和蓝牙来追踪用户的精确位置，这点我们并不感到意外。但在对该软件展开彻底审查后，安全研究人员发现它还能够读取、删除或更改所有内容。除了覆盖任何其它已安装的软件、并阻止手机进入待机休眠模式，其它权限则包括拨打电话、以及禁用设备锁屏。其次，《Hayya》也能够通过苹果 App Store / 谷歌 Play 商店获取。乍一看，它似乎是一款更加温和的 App，主要用于跟进赛事信息和访问当地的免费地铁系统。然而经过一番检查，Øyvind Vasaasen 同样发现了危险的信号。一方面，它有权在几乎没有任何限制的情况下，分享手机上的信息。另外它可追踪用户位置、防止设备进入睡眠待机模式，并可查看用户的网络连接。

三 | 借助上述两款 App，卡塔尔政府可以完全控制设备上的数据存储、包括删改信息的能力。至于到时候该政策的实际执行力度有多强，目前暂不得而知。

四 | 毕竟此前沙特也有过类似的要求，但并非强制性。
