On January 20, 2025, in the control hall of the All Superconducting Tokamak Nuclear Fusion Experiment (EAST) on Science Island in Hefei, Anhui, the number on the screen finally froze at 1066 seconds. At this moment, China's "artificial sun" achieved continuous "burning" for over 1000 seconds at a high temperature of 100 million degrees Celsius for the first time, breaking the limit record for human controllable nuclear fusion energy research. This temperature is equivalent to 10 times the core temperature of the Sun, and the stable operation lasting for thousands of seconds means that China has simulated the extreme environment required for future fusion reactors on an experimental device for the first time, marking a critical stage in China's transition from basic research to engineering practice.
