===Experiments on fluid deuterium at the National Ignition Facility, 2018===
In August 2018, scientists announced new observations<ref>{{cite journal |last1=Celliers |first1=Peter M. |last2=Millot |first2=Marius |last3=Brygoo |first3=Stephanie |last4=McWilliams |first4=R.

Remarkable agreement is found between the experimental data and the predictions based on [[quantum Monte Carlo]] simulations, which is expected to be the most accurate method to date. This may help researchers better understand [[Gas giant|giant gas planets]], such as Jupiter, Saturn and related [[exoplanet]]s, since such planets are thought to contain a lot of liquid metallic hydrogen, which may be responsible for their observed powerful [[magnetic field]]s.<ref name="NYT-20180816">{{cite news |url=https://www.nytimes.com/2018/08/16/science/metallic-hydrogen-lasers.html |title=Settling Arguments About Hydrogen With 168 Giant Lasers |work=The New York Times |first=Kenneth |last=Chang |date=16 August 2018 |access-date=18 August 2018}}</ref><ref name="SCI-20180816">{{cite web |url=https://carnegiescience.edu/news/under-pressure-hydrogen-offers-reflection-giant-planet-interiors |title=Under pressure, hydrogen offers a reflection of giant planet interiors |publisher=Carnegie Institution for Science |date=15 August 2018 |access-date=19 August 2018}}</ref>
