It’s official: A U.S. Department of Energy lab produced a controlled nuclear fusion reaction that released more energy than it consumed.

On December 5, just after 1:03 a.m., 192 lasers at the National Ignition Facility converged on a small gold cylinder that contained a tiny bead of fuel composed of two isotopes of hydrogen, deuterium and tritium. In a flash, the cylinder vaporized, emitting X-rays that bombarded the fuel pellet, turning its outer diamond layer into an expanding plasma that compressed the fuel inside to the point where its nuclei fused and released a tremendous amount of energy.
