Department of Energy, Office of Science

In the 1980s, Saul Perlmutter at the Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (LBNL) and his collaborators realized that they could use data about supernovae to research the history of the universe. They expected to see that very distant supernovae appear a bit brighter than they would in an expanding universe that wasn’t slowing in its growth. The data revealed something else entirely.

National Ignition Facility Reveals How Hydrogen Becomes Metallic Inside Giant Gas Planets
Lawrence Livermore National Laboratory

Swirling dense metallic hydrogen dominates the interiors of Jupiter, Saturn and many extra-solar planets. Building precise models of these giant planets requires an accurate description of the transition of pressurized hydrogen into this metallic substance – a long-standing scientific challenge. In a paper published by Science, a research team led by scientists at Lawrence Livermore National Laboratory describes optical measurements of the insulator-to-metal transition in fluid hydrogen, resolving discrepancies in previous experiments and establishing new benchmarks for calculations used to construct planetary models. The multi-institution team included researchers from the French Alternative Energies and Atomic Energy Commission, University of Edinburgh, University of Rochester, Carnegie Institution of Washington, University of California, Berkeley and The George Washington University.

A cloud of gas 300,000 light-years long is arching around the Milky Way, shunted away from two dwarf galaxies orbiting our own. For decades, astronomers have wanted to know which of the two galaxies, the Large and Small Magellanic Clouds, is the source of the gas that has been expelled as the two galaxies gravitationally pull at one another. The answer will help astronomers understand how galaxies form and change over time.
