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

A |     A dark money group called the Resources Legacy Fund (RLF) that was awarded grant money by the Leonardo DiCaprio Foundation provided funds to a law firm linked to “climate nuisance lawsuits” across the United States, Fox News reports, citing findings made by the watchdog group Government Accountability & Oversight (GAO).,According to the media outlet, GAO managed to obtain emails that were exchanged between major philanthropist Dan Emmett and Ann Carlson, a climate professor at UCLA, in 2017 when they were working with a law firm called Sher Edling to raise money for the firm’s efforts to sue oil companies on behalf of state and local governments.,In their correspondence, Emmett and Carlson mention how Sher Edling’s director of strategic client relationships Chuck Savitt received help from Terry Tamminen in the latter’s capacity (at the time) as CEO of the Leonardo DiCaprio Foundation.,"Chuck Savitt who is heading this new organization behind the lawsuits has been seeking our support," Emmett wrote in one of the emails to Carlson. "Terry Tamminen in his new role with the DiCaprio Foundation has been a key supporter.”,He also forwarded a message to Carlson that Savitt had sent him a few days prior.,"Wanted to let you know that we filed the first three lawsuits supported by the Collective Action Fund on Monday," Savitt wrote in the missive. "These precedent setting cases call on 37 of the world's leading fossil fuel companies to take responsibility for the devastating damage sea level rise - caused by their greenhouse gas emissions - is having on coastal communities.",Con Artists Swindle Woman Out of Over $800,000 via 'Leonardo DiCaprio & Scientology' Scheme12 May, 18:57 GMT,As the media outlet points out, the Collective Action Fund for Accountability, Resilience and Adaptation was managed at the time by the RLF, and two months before the aforementioned correspondence was exchanged, the Leonardo DiCaprio Foundation announced that they would contribute some $20 million in grants to various climate and conservation causes, with one of the recipients of those grants being the RLF.,The said grant was awarded to the dark money group "to support precedent-setting legal actions to hold major corporations in the fossil fuel industry liable," Fox notes, adding that the announcement has since been deleted (although it remains archived).,Between 2017 and 2020, the RLF reportedly provided more than $5.2 million to Sher Edling, with the dark money group’s spokesman Mark Kleinman telling Fox that they had provided grants to the firm so the latter would “pursue charitable activities to hold fossil fuel companies accountable for the accuracy of information they had disseminated to consumers and the public about the role their products played in causing climate change.",Since 2017, Sher Edling has sued major oil companies on behalf of both state and local governments in the United States, alleging that the said companies have "deceived the public about climate change," with most of these lawsuits currently being ongoing, the media outlet adds.。

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.
