ANIMATION “Sterile neutrinos” are theoretically predicted new particles that offer an intriguing possibility in the quest for understanding the dark matter in our universe. Unlike the known “active” neutrinos in the Standard Model (SM) of particle physics, these sterile neutrinos do not interact with normal matter as they move through space, making them very difficult to […]

New research by LLNL scientists shows that satellite measurements of the temperature of the troposphere (the lowest region of the atmosphere) may have underestimated global warming over the last 40 years. One of the physical processes they looked at was tropical water vapor like shown in this NASA image. Credit: […]

A standoff detonation of a nuclear device irradiates an asteroid and deposits energy at and beneath the surface. In this work, two neutron yields (50 kt and 1 Mt) and two neutron energies (14.1 MeV and 1 MeV) were the primary case studies compared side-by-side. The black dots represent the […]

This illustration captures an exoplanet as it is about to cross in front of – or transit – its star.

The first-ever shot with explosives was recently conducted at the National Ignition Facility. Credit: LLNL The first-ever shot to study a high explosive sample was recently conducted at the National Ignition Facility (NIF), the world’s most energetic laser. The results from the shot included novel data that will help researchers unlock the […]
