The main structure of a mega fully steerable radio telescope was capped in northwest China's Xinjiang Uygur Autonomous Region on Sunday, marking another step forward in the construction of the major scientific research infrastructure project in the country.
Located in the foothills of the Tianahan Mountains in Qitai County, the telescope will feature a single dish measuring 110 meters in diameter and weigh more than 6,000 tons. The fully steerable dish will allow the telescope to observe 75 percent of celestial bodies in the sky.
Construction on the 110-meter-diameter telescope started in September 2022 and is expected to be completed in 2028.
The next phase of the construction will involve equipment installation and system testing.
China is also building another fully steerable radio telescope with a diameter of 120 meters, so far the world's largest, in northeast China's Jilin Province.
The Green Bank Telescope in West Virginia, the United States, currently holds the title as the world's largest operational fully steerable radio telescope, with its dish measuring 100 meters by 110 meters.
Compared with fixed radio telescopes of the same size, fully steerable radio telescopes can observe a larger part of the sky.

Egypt has ordered measures to cut electricity consumption after the U.S. and Israeli war against Iran disrupted oil and gas supplies, requiring shops to close early and roadside advertising to be switched off.
Shops and restaurants must shut at 21:00 under the new curfew, nearly four hours earlier than usual, curtailing Egypt’s peak evening business hours.
For restaurant manager Yasser Hamido, the closures mean reshuffling shifts, giving workers breaks, and rethinking how to keep the business running during shorter hours.
"We accept these measures, because we know it's important for the country. We'll just have to adapt by giving some of our workers a break and rescheduling shifts, then wait and see what happens," Hamido said.
The restrictions are already reshaping daily life. Egypt, known for its bustling streets and vibrant nightlife, is turning dark. Even billboards and public lights are being switched off. Only popular tourist destinations such as Sharm El Sheikh and Hurghada on the Red Sea have been exempted.
"The latest conflict in the Middle East has led to a shortage in natural gas supplies globally, including Egypt. This, coupled with energy price hikes, have made it difficult for Egypt to import gas for electricity generation. Most of Egypt's power stations are run by natural gas," said economic analyst Hossam Gawish.
The government says the energy import bill had jumped from 1.2 billion U.S. dollars in January to above 2.1 billion U.S. dollars in mid-March, forcing it to take several measures to regulate electricity consumption and avoid power cuts.
But, the early closure of all commercial, sports and entertainment activities has been controversial. Although the government outlined the economic benefits of this decision at a critical time, it has been widely criticized by a large segment of the Egyptian population.
Most Egyptians typically spend their leisure hours in the evening, when cooler temperatures draw people outdoors. Those hours account for a significant share of economic activity, and businesses have raised alarm over potential losses from early closure requirements.
"When you reduce operating hours, it leads to a significant drop in revenue and even GDP, a drop in pay for workers and a drop in the purchasing power of Egyptians. But it's a habit. Most Egyptians have to readjust their habits to be like many countries that normally close early. It will take time however," said Gawish.
Facing public backlash, officials said the early shop-closure policy will run on a trial basis and be reassessed in May.
