With a powerful laser blast, scientists near a nuclear fusion milestone
A National Ignition Facility experiment produced a record 1.3 million joules of fusion energy
Scientists at the National Ignition Facility have produced record-breaking energy in a nuclear fusion experiment. Such fusion experiments, like the 2016 test shown in this colorized image, use powerful laser blasts to compress hydrogen fuel and kick off fusion.
