Chinese-made infrared telescope with domestic detectors achieves astronomical imaging, reducing foreign reliance_我的网站

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 | The makers of Kalamkaval have officially confirmed that the film will now arrive in theatres on December 5. The announcement comes after the team reviewed the final stage of post-production and decided that the film would benefit from a slightly later window. The move follows earlier communication from the production house that hinted at a stronger and more precise theatrical plan. A new date and a clearer rollout plan Kalamkaval features Mammootty and Vinayakan in central roles. Mammootty is believed to play a morally complex character whose motivations drive the core tension, while Vinayakan appears as a police officer whose track intersects with the unfolding drama. The pairing has already created interest, especially as both actors are known for grounded and unpredictable performances. The film marks the directorial debut of Jithin K Jose, who previously wrote the story for Kurup. The screenplay is co-written by Jithin and Jishnu Sreekumar. With this project, Jithin steps into a more expansive creative role, shaping a thriller that leans heavily on atmosphere and shifting moral lines. Cast, craft and tone The supporting cast includes Jibin Gopinath, who earned attention for his recent turn in Dies Irae. The team behind the film features cinematographer Faisal Ali, editor Praveen Prabhakar, composer Mujeeb Majeed and production designer Shajie Naduvil. Their combined craftsmanship is expected to lend the film its moody palette and grounded visual identity. Kalamkaval has received a U/A 16+ certification, signalling a tone that remains intense while still accessible to a broad audience. Early stills and teasers hinted at a narrative that draws from real world textures and psychological unease. With the release pushed into December, the makers are positioning the film for a more focused promotion cycle.
