The Chinese experimental nuclear fusion reactor smashed the previous record, set by France’s Tore Supra tokamak in 2003, where plasma in a coiling loop remained at similar temperatures for 390 seconds. EAST had previously set another record in May 2021 by running for 101 seconds at an unprecedented 216 million F (120 million C). The core of the actual sun, by contrast, reaches temperatures of around 27 million F (15 million C).

“The recent operation lays a solid scientific and experimental foundation towards the running of a fusion reactor,” experiment leader Gong Xianzu, a researcher at the Institute of Plasma Physics of the Chinese Academy of Sciences, said in a statement.
