Scientists Decode the Origin of Universe’s Heavy Elements in the Light from a Neutron Star Merger

On Aug. 17, scientists around the globe were treated to near-simultaneous observations by separate instruments that would ultimately be confirmed as the first measurement of the merger of two neutron stars and its explosive aftermath.

How Berkeley Lab Software Helped Lead to the 2017 Nobel Prize in Physics

The Nobel Prize in Physics was awarded to scientists in the LIGO Scientific Collaboration who discovered gravitational waves. Software tools developed by researchers at Berkeley Lab’s Computational Research Division played a key role in enabling the analysis of the vast quantities of data generated by LIGO.

Berkeley Lab Intern Focuses on Using Light for Spaceflight

Elliot Heywood had dreamed of landing an internship at the science lab in the hills not far from his school in Lafayette, California, but he never could have imagined this dream would take wing as a summerlong stint researching an ultrafast interplanetary propulsion system. In May, after a friend and fellow high school senior at

New Simulations Could Help in Hunt for Massive Mergers of Neutron Stars, Black Holes

Scientists at Berkeley Lab have developed new computer models to explore what happens when a black hole joins with a neutron star – the superdense remnant of an exploded star.

Dark Matter Day Is Approaching … but Don’t Be Afraid of the Dark

A global hunt for the universe’s missing matter is underway, and this autumn everyone is invited to join in. On and around October 31, 2017, events around the world will celebrate the hunt for the universe’s unseen “dark matter.”

Future Shines Bright for Space Science Intern Zachary Raha

Zachary Raha was the kind of kid who always had a side project. Today, Raha—who recently completed a Science Undergraduate Laboratory Internship (SULI) with Nobel laureate Saul Perlmutter of the Physics Division—keeps himself busy with maps of a different scale: the expansion history of the universe as illustrated by Type Ia supernovae.

Rare Supernova Discovery Ushers in New Era for Cosmology

Using an automated supernova-hunting pipeline based at NERSC, astronomers have captured multiple images of a gravitationally lensed Type Ia supernova. This detection is currently the only one of its kind, but astronomers believe that if they can find more, they may be able to measure the rate of the universe’s expansion within 4 percent accuracy. Two Berkeley Lab researchers have a method for identifying more of these events using existing wide-field surveys.

New Measurements Suggest ‘Antineutrino Anomaly’ Fueled by Modeling Error

Results from a new study involving Berkeley Lab scientists could explain a mismatch between predictions and recent measurements of ghostly particles streaming from nuclear reactors—the so-called “reactor antineutrino anomaly” that has puzzled physicists since 2011.

New Study Maps Space Dust in 3-D

A new Berkeley Lab-led study provides 3-D views of space dust in the Milky Way, which could help us understand the properties of this dust and how it affects views of distant objects.

Attention Earthlings: Help Wanted in Finding a New Planet

Data research for a Berkeley Lab-led dark energy experiment benefits citizen science project that seeks the public’s help in the hunt for a hypothesized Neptune-like Planet Nine.
