Scientists Discover Jupiter-Like Planet in a Young Star System

For the first time, Lawrence Livermore scientists as part of an international team, have discovered the most Jupiter-like planet ever seen in a young star system, lending clues to understanding how planets formed around our sun.

New Analysis of Supernovae Helps Explain How Some Young Stars Exploded Sooner Than Expected

Scientists have been fascinated by a series of unusual exploding stars--outcasts beyond the typical cozy confines of their galaxies. A new analysis of 13 supernovae -- including archived data from NASA's Hubble Space Telescope -- is helping astronomers explain how some young stars exploded sooner than expected, hurling them to a lonely place far from their host galaxies.

Researchers Study Materials Under Extreme Pressure Utilizing Neutron Diamond Anvil Cells

Researchers with Oak Ridge National Laboratory’s (ORNL’s) Spallation Neutron Source (SNS) have developed technology to squeeze materials with a million times the pressure of the earth’s atmosphere while studying them with neutrons. When they bombard these materials with neutrons, the materials provide an unprecedented picture of the changing nature of matter under extreme pressure.

Baryon Antibaryon Symmetry Experiment Reports Most Precise Charge-to-Mass Ratio Comparison of Protons to Antiprotons

In a paper published today in Nature, the Baryon Antibaryon Symmetry Experiment (BASE1) at CERN2's Antiproton Decelerator (AD), reports the most precise comparison of the charge-to-mass ratio of the proton to that of its antimatter equivalent, the antiproton. The charge-to-mass ratio — an important property of particles — can be measured by observing the oscillation of a particle in a magnetic field. The new result shows no difference between the proton and the antiproton, with a four-fold improvement in the energy resolution compared with previous measurements.

Researchers Study Interaction of Strong Laser Pulses with Glass Nanoparticles

A team of physicists and chemists from the Laboratory of Attosecond Physics at the Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics has studied the interaction of light with tiny glass particles.

Researchers Make Most Precise Measurements of Charge-to-Mass Ratio of Protons and Antiprotons

The work, published in Nature, was carried out using CERN's Antiproton Decelerator, a device that provides low-energy antiprotons for antimatter studies.

South Pole-Based Icecube Experiment Detects Evidence of Fourth Ultra-High Energy Neutrino

Evidence of a fourth ultra-high energy neutrino—the highest-energy neutrino yet—has been detected by the South Pole-based IceCube experiment, a project that Berkeley Lab researchers helped build and to which they currently contribute analysis.

Neutrinos May Provide Key to the Evolution of the Universe

Every second, a trillion neutrinos from the sun and other celestial objects pass through our bodies like we’re invisible. And while neutrinos are the most abundant subatomic particles with mass in the universe –– a billion times more than those that make up the planets, stars and humans –– they so rarely interact with other matter that they are poorly understood and tricky to detect.

MicroBooNE Detector Records Images of Tracks of Cosmic Muons

A school bus-sized detector packed with 170 tons of liquid argon has seen its first particle footprints.

Successful Production of Holmium Samples Could Enable Sensitive Measurement of Neutrino Mass

To measure the mass of neutrinos, scientists study radioactive decays in which they are emitted. An essential ingredient is the decay energy which corresponds to the mass difference between the mother and daughter nuclei. This decay energy must be known with highest precision.
