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.
中国新闻网周三报道,中国科学家周三公布了中国新一代地基红外望远镜拍摄的第一套完整观测图像,这填补了我国近红外天文观测能力的空白,也减少了对国外红外探测器技术的依赖。
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.
这台80厘米的近红外望远镜于2024年10月安装在中国西北青海省冷湖乡的赛什腾山。由中山大学和几个合作机构联合开发,这台望远镜是中国首台使用国产科研级InGaAs和HgCdTe探测器,在1.2微米的J波段和2.2微米的K波段实现科学成像的望远镜。
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.
这台望远镜支持无人值守的远程操作,并且可以在15秒内锁定天空中的任何目标。它的红外功能可以穿透星际尘埃,让它能够观测到光学望远镜难以捕捉到的寒冷且遥远的天体。
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.
中山大学物理与天文学院的马宾教授领导了发布红外望远镜观测图像的研究团队,他表示,望远镜的三项核心天文观测能力在运行中都得到了充分验证。
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.
它快速响应并跟踪了多个伽马射线暴和超新星事件,记录了爆炸后它们红外余辉的演变。它持续监测棕矮星,精确捕捉它们大气亮度的周期性变化。通过图像叠加技术,它还观察了数十亿光年之外的活动星系。
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.
自从在冷湖部署以来,该系统已经为超过10个中国研究机构提供了红外观测支持,为未来大型红外望远镜的建设积累了宝贵经验。
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.
冷湖镇,正在建设世界级天文观测基地,被称为“地球上最像火星的地方”。据中国科学院报道,一篇发表于2021年8月18日的《自然》杂志文章称,这个天文观测基地可以与世界顶级观测站相媲美。
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.
据新华社报道,曾因丰富的石油资源在上世纪50年代繁荣一时的冷湖,现在正逐渐成为一个顶级天文观测地和火星主题的旅游目的地。
