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.

B | “人民空军”微信公众号8月24日发布消息称，北京时间8月23日，中埃“文明之鹰-2026”空军联合训练迎来首个飞行训练日。中埃空军联合训练的首个飞行日，训练课目是异型机1对1对抗空战。从“人民空军”发布的视频中可以看到，中方飞行员驾驶着我国自主研制的歼-16重型歼击机与埃及空军装备的法制“阵风”战机进行了对抗演习。

C | 24日接受《环球时报》记者采访的军事专家表示，此次中埃空军联合训练，既能够有效检验我方装备，也能切身感知“阵风”战机的性能。 “人民空军”消息称，23日，随着中埃空军的战机接续升空，双方飞行员在贴近实战的场景下，展开激烈较量。

D | 据介绍，飞行训练前，中埃飞行员分别授课，介绍双方参训装备性能；随后，双方对联合训练课目进行深入研究讨论，明确飞行安全规则、空域管制规定、起降方法和特情处置预案。军事专家张学峰24日告诉《环球时报》记者，歼-16为双发重型多用途战斗机，载油量可达9吨以上，该机滞空时间长、载弹量大，机载雷达探测距离更远，中远距离作战优势显著，是世界同代战斗机中航程最远的机型之一。同时歼-16可适配多型弹药，拥有强大的对地、对海打击能力，是名副其实的空中多面手。张学峰说：“歼-16远赴埃及参加联合训练，不仅充分验证了该型战机远程转场、跨域作战的实际能力，也为应对周边同类型装备威胁积累宝贵的实战化演训经验。” 中埃“文明之鹰-2026”空军联合训练也吸引多家外媒报道。

E | 彭博社24日称，根据埃及军方发布的照片，歼-16和“阵风”正在埃及开展联合训练。该媒体提到，中国歼-10战机因在去年的印巴冲突中对战“阵风”战机的作战表现受到关注。

F | 沙特《中东报》24日援引埃及军方的声明称，“文明之鹰-2026”的参演装备包括多种型号的多用途战斗机，演习将在埃及境内的多个空军基地进行，为期数日。 “埃及空军列装的‘阵风’战机或为F3标准，可配备有源相控阵雷达，这也是在中外联合演训中，中国空军面对的技术水平最为先进的西方战机。”张学峰表示，在空战场景下，歼-16可高效夺取制空权，在己方电子战飞机掩护下，还可突破敌方防空体系，对地面目标实施精确打击。作为重型战斗机，歼-16配备两台大推力、大推重比发动机，机动水平与中型的“阵风”战斗机总体相当，各有优势，能够在近距格斗环节充分检验双方的技战术运用水平。
