£2.2bn superlab where scientists are creating a star on Earth | Mail Online

According to the National Ignition Facility (NIF) team in Livermore, on November 2 they fired up the 192 lasers beams at the centre of the reactor and aimed them at a glass target containing tritium and deuterium gas.

The resulting release of energy was of a magnitude of 1.3 million mega joules, which was a world record and the peak radiation temperature measure at the core was approximately six million degrees Fahrenheit.

For a direct comparison, the temperature at the centre of the sun is 27 million degrees Fahrenheit.
