Chinese scientists have, for the first time ever, sent back the X-ray images of a full moon shot from space using the Einstein Probe (EP) satellite on Tuesday, coinciding with the moon-themed traditional Mid-Autumn Festival.
The images were captured by the follow-up X-ray telescope FXT aboard the satellite, showcasing the moon's appearances in X-ray spectrum, which differ from its typical images.
The FXT telescope was developed under the leadership of the the Institute of High Energy Physics of the Chinese Academy of Sciences.
Compared to other X-ray satellites, the FXT telescope boasts a large imaging field, excellent X-ray energy resolution, and a high effective area.
It can reveal the distribution of elements such as oxygen, iron, magnesium, aluminum and silicon on the lunar surface, holding significant value for conducting lunar-related scientific research.

China's domestically developed T1200-grade ultra-high-strength carbon fiber holds broad application prospects in strategic emerging industries, according to its developer.
The country on Wednesday unveiled SYT80, a domestically developed T1200-grade ultra-high-strength carbon fiber, marking a major breakthrough in the China's high-performance carbon fiber technology.
This new material has achieved a hundred-tonne-level annual production capacity, making China the first nation to mass-produce this caliber of fiber, according to its developer, China National Building Material Group Co., Ltd. (CNBM).
Featuring lightweight and high-strength properties, the fiber's diameter is less than one-tenth that of a human hair, and yet its tensile strength is 10 times that of ordinary steel and its density is only one-quarter of steel's.
"Compared with the previous-generation T1100, T1200 has seen its tensile strength increase by more than 14 percent. With its ultimate lightweight and high-strength characteristics, T1200 can achieve weight reduction of over 10 percent for equipment in related fields. It holds broad application prospects in strategic emerging industries such as commercial aerospace, low-altitude economy, and humanoid robots," said Chen Qiufei, head of T1200 ultra-high-strength carbon fiber research and development at Zhongfu Shenying Carbon Fiber Company, a subsidiary of China National Building Material Group.
The new material also possesses many other outstanding properties.
As the fiber undergoes carbonization at nearly 2,000 degrees Celsius during production, its chemical properties remain stable and its corrosion resistance is excellent.
This fiber material also features strong fire and flame retardant properties, offering good safety performance.
The development of this fiber material demonstrates China's fully independent and controllable capabilities across the entire industrial chain of high-performance carbon fiber, spanning technologies and equipment as well as the transition from laboratory research to mass production, said Zhou Yuxian, chairman of CNBM.
