The Korea Superconducting Tokamak Advanced Research or KSTAR had previously set a record of reaching 100 million degree plasma for 30 seconds in 2021, reported the Korea Institute of Fusion Energy (KFE).
Nuclear fusion happens when two light atoms’ nuclei merge to form a single heavier one, generating a huge release of energy.
This phenomenon powers stars, including the sun, which is why KSTAR has been nicknamed an “artificial sun”.
