The Joint European Torus (JET)—the largest and most powerful operational fusion reactor in the world—has replicated the nuclear processes that power the sun, generating a record-breaking amount of fusion-based energy.

The UK Atomic Energy Authority (UKAEA) announced on Tuesday that scientists and engineers at JET had successfully generated 59 megajoules of sustained fusion energy. This more than doubled the record set at the site in 1997, when it produced 22 megajoules of energy.
