South Korean Scientists Set New Record in “Artificial Sun” Experiment

South Korean scientists at the Korean Fusion Energy Institute (KFE) achieved a groundbreaking milestone by running the KSTAR nuclear reactor, known as the “artificial sun,” at 100 million degrees Celsius for 48 seconds. This achievement, surpassing the previous 30-second record, marks significant progress in nuclear fusion technology aimed at producing clean and limitless energy. KSTAR Director Si-Woo Yoon highlighted the importance of the 48-second record and outlined the goal of sustaining this temperature for 300 seconds by 2026.
