New Path Forward for Next-Generation Lithium-Ion Batteries

A new study by Berkeley Lab researchers Dong-Hwa Seo, Alex Urban, Jinhyuk Lee, and Gerd Ceder (from left) sheds light on how lithium-rich cathodes work, opening the door to higher capacity batteries.

A team led by Gerbrand Ceder has made a major advance in understanding the chemical processes in “lithium-rich cathodes,” which hold promise for a higher energy lithium-ion battery.

$40M to Establish New Observatory Probing Early Universe

The site currently hosts the Atacama Cosmology Telescope (bowl-shaped structure at upper right) and the Simons Array (the three telescopes at the bottom left, middle and right). The Simons Observatory will incorporate several new telescopes and set the stage for a next-generation experiment. (University of Pennsylvania)

A new astronomy facility, the Simons Observatory, is planned in Chile’s Atacama Desert to boost ongoing studies of the evolution of the universe, from its earliest moments to today. The observatory will probe the subtle properties of the universe’s first light, known as cosmic microwave background radiation.

Berkeley Lab, UC Berkeley Scientists to Participate in New NASA Space Telescope Project

Berkeley Lab and UC Berkeley scientists will play a role in a new NASA space telescope project exploring dark energy, alien worlds and the evolution of galaxies, galaxy clusters and the large-scale structure of the universe.

New Galaxy-hunting Sky Camera Sees Redder Better

A newly upgraded camera that incorporates light sensors developed at Berkeley Lab is one of the best cameras on the planet for studying outer space at red wavelengths too red for the human eye to see.

Explore Galaxies Far, Far Away at Internet Speeds

Scientists have released an “expansion pack” for a virtual tour of the universe that you can enjoy from the comfort of your own computer. The latest version of the publicly accessible images of the sky roughly doubles the size of the searchable universe from the project’s original release in May.

Supernova Twins: Making Standard Candles More Standard Than Ever

Supernova Factory group (SN factory) - Greg Aldering, Kyle Boone, Hannah Fakhouri and Saul Perlmutter.

Type Ia supernovae are bright “standard candles” for measuring cosmic distances. Standard enough to discover dark energy, they’re far from identical. Researchers at the Berkeley Lab-based Nearby Supernova Factory have shown that supernova twins with closely matching spectra double the accuracy of distance measures.

DESI, an Ambitious Probe of Dark Energy, Achieves its Next Major Milestone

Paul Preuss DESI-Mayall-sky feature

The U.S. Department of Energy has announced approval of Critical Decision 2 (CD–2), authorizing the scientific scope, schedule, and funding profile of DESI, the Dark Energy Spectroscopic Instrument, an exceptional apparatus designed to improve our understanding of the role of dark energy in the expansion history of the universe.

Celeste: A New Model for Cataloging the Universe

The glint off the dome is moonlight; the small and large Magellanic clouds can be seen in the background. (Image: Dustin Lang, University of Toronto)

A Berkeley Lab-based research collaboration of astrophysicists, statisticians and computer scientists has created a new statistical analysis model designed to enhance one of modern astronomy’s most time-tested tools: sky surveys.
