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.

。 中新网海口8月20日电 (记者 王子谦)交通运输是国民经济的基础性、先导性、战略性产业。封关运作后的海南,如何更好布局综合交通运输发展体系,带动自贸港建设?
在20日举行的“开局起步‘十五五’”系列主题新闻发布会——《海南省“十五五”综合交通运输规划》专场上,海南省发展和改革委员会主任綦树利表示,“十五五”时期,要紧扣交通强国建设战略部署和海南自由贸易港发展需要,推动实现交通现代化,基本建成立足海南、服务全国、面向“两洋”、联通世界的现代化综合交通运输体系,有效支撑构建国内国际双循环战略交汇点。
为此,《海南省“十五五”综合交通运输规划》提出“五个新”具体目标。
枢纽能级达到新高度
打造面向太平洋、印度洋的航空区域门户枢纽和西部陆海新通道国际航运枢纽,是海南自贸港服务和融入新发展格局、推进高水平制度型开放的核心支撑。綦树利表示,“十五五”时期海南自贸港“两个枢纽”功能要显著增强。
为此,海南将加快打造自由贸易港交通枢纽体系:打造面向太平洋、印度洋的航空区域门户枢纽,适度超前推进三亚新机场、美兰机场三期扩建工程等建设;打造西部陆海新通道国际航运枢纽,高标准建设洋浦港,高质量推进海口港转型;打造现代化综合交通枢纽,以“零距离换乘、无缝化衔接”为核心导向,完善枢纽功能与集疏运配套,推动综合交通枢纽提质发展。

通道规模实现新拓展
“十四五”时期,海南重点补对外通道短板,建成海口美兰机场二期、海南洋浦区域国际集装箱枢纽港扩建工程(一阶段)、海口新海滚装码头客运综合枢纽等一系列重点项目。展望“十五五”,綦树利说表示,空中、海上、陆上、跨海峡及低空多维度对外通道更加畅通。
具体来看,海南将建设面向两洋的空中大通道,完善“两圈一带”对外联通体系;打造外联内畅的海上大通道,加密东南亚、东北亚等区域航运网络,逐步延伸中东、大洋洲近洋航线;拓展坚强韧性的陆上大通道,依托湛海高铁及G15、G75等国家干线通道强化陆路连接;加快建设琼州海峡“黄金水道”,完善以海南至广东为主线、海南至广西为支线的跨海峡通道布局,构建跨琼州海峡低空通道,大幅提升跨海通道能力。
网络质量迈上新台阶
立体交通网络为经济发展提供重要基础支撑。綦树利表示,“十五五”期间,海南将构建现代化综合立体交通网络,岛内快速网、干线网、基础网更加完善,枢纽集疏运体系高效衔接。
为此,海南将建设高效衔接的快速网,实施G98环岛高速公路提档扩容工程;构建安全韧性的干线网,实施国省干道提质升级工程,挖潜既有西环普速铁路货运能力;打造便捷通畅的基础网,推进铁路专支线进港入园,持续推进“四好农村路”建设;完善“双环”旅游公路体系,形成“两环多连”的“珍珠链”网络;构建健康安全低空网。
服务品质完成新跨越
如今的海南,交通运输服务品质提档增效,环岛高铁高峰期发车间隔缩短至10分钟,全省二级及以上公路客运站、省际和市际客运班线电子客票覆盖率均达到100%,全省建制村通客车继续保持100%。
“十五五”时期,海南把提升自由便利运输服务能级摆在显著位置,提出物流降本增效取得明显成效。

綦树利表示,海南将健全全岛同城化运输体系,推动环岛铁路公交化运营,提升城乡出行均等化服务水平,推动旅客联程运输发展;建设现代化物流设施网络,大力发展多式联运,培育“高铁快运+空铁联运”、低空物流等新业态;提升口岸交通基础设施支撑能力,有力支撑货物“一次报关、一次查验、一次通行”及人员“一次过检、无感通关”。
改革创新取得新突破
“十四五”期间,海南交通运输重大改革创新持续破局:“中国洋浦港”船籍港登记在册国际船舶数量及总运力居全国自贸区(港)第一;“环岛旅游公路创新发展”交通强国建设试点任务全面完成;有人机、无人机总飞行量排名全国前列,低空飞行密度、空中游览和跳伞飞行发展连续多年位列全国第一。
深化交通运输体制机制改革,是未来五年海南交通运输工作的重点方向。海南将深化重点领域改革,统筹推进航空、铁路、公路、航运、低空等领域制度创新;创新投融资体制机制,引导社会资本参与交通基础设施投资建设和运营管理;建设统一开放大市场,健全市场制度,优化要素配置,完善信用监管。
綦树利表示,今后五年,努力把宏伟蓝图变成美好现实,为海南自由贸易港高质量发展当好先行者。(完)
