Gigantic telescope CHINA’S Five-hundred-meter Aperture Spherical Radio Telescope (FAST), the world’s largest single-dish radio telescope, has identified over 800 new pulsars since its launch in 2016, its operator said Tuesday. The number of new pulsars discovered by FAST is more than three times the total number of pulsars discovered by foreign telescopes during the same period, said Jiang Peng, chief engineer of the telescope. Pulsar observation is an important task for FAST, which can be used to confirm the existence of gravitational radiation and black holes, and help find answers to many other major questions in physics. Great Wall relics THE China Great Wall Museum on Tuesday began seeking cultural relics from home and abroad in a move to further promote the research, collection and protection of the cultural heritage of the Great Wall. Cultural relics include objects, photographs, documents and construction tools that reflect the construction and development of the Great Wall during various periods of Chinese history.
