Lab team uses giant lasers to compress iron oxide, revealing the secret interior of rocky exoplanets

Feb. 11, 2021- 
Advances in astronomical observations have resulted in the discovery of an extraordinary number of extrasolar planets, some of which are believed to have a rocky composition similar to Earth. Learning more about their interior structure could provide important clues about their potential habitability. Led by Lawrence Livermore National Laboratory (LLNL), a team of researchers aims to...

High performance computing (HPC) simulations exploring star formation by Lawrence Livermore astrophysicist Richard Klein were among select research highlights featured by NASA at the recent supercomputing conference in Austin, Texas.Klein’s "Simulating Star Formation: From Giant Molecular Clouds to Protostellar Clusters" presentation is now on NASA’s website.The origin of star clusters...

First stars in the universe left a unique signature

June 30, 2015- 
Determining the chemical abundance pattern left by the earliest stars in the universe is no easy feat. A Lawrence Livermore National Laboratory (LLNL) scientist is helping to do just that.The first stars in the universe formed about 400 million years after the Big Bang (estimated at 13.8 billion years ago). Inside of these stellar furnaces, nuclear processes fused the hydrogen and helium made...

Planets around stars are the rule rather than the exception

Jan. 12, 2012- 
LIVERMORE, Calif. --There are more exoplanets further away from their parent stars than originally thought, according to new astrophysics research. In a new paper appearing in the Jan. 12 edition of the journal, Nature , astrophysicist Kem Cook as part of an international collaboration, analyzed microlensing data that bridges the gap between a recent finding of planets further away...
