Dark Matter Experiment’s Central Component Takes a Deep Dive – Nearly a Mile Underground

Last week, crews at the Sanford Underground Research Facility in South Dakota strapped the central component of LUX-ZEPLIN – the largest direct-detection dark matter experiment in the U.S. – below an elevator and s-l-o-w-l-y lowered it 4,850 feet down a shaft formerly used in gold-mining operations.

DESI Opens Its 5,000 Eyes to Capture the Colors of the Cosmos

A new instrument mounted atop a telescope in Arizona has aimed its robotic array of 5,000 fiber-optic “eyes” at the night sky to capture the first images showing its unique view of galaxy light.

Study Reveals ‘Radical’ Wrinkle in Forming Complex Carbon Molecules in Space

A team of scientists has discovered a new possible pathway toward forming carbon structures in space using a specialized chemical exploration technique at Berkeley Lab’s Advanced Light Source.

VIDEO: Particle Accelerators Drive Decades of Discoveries at Berkeley Lab and Beyond

This video and accompanying article highlight the decades of discoveries, achievements and progress in particle accelerator R&D at Berkeley Lab. These accelerators have enabled new explorations of the atomic nucleus; the production and discovery of new elements and isotopes, and of subatomic particles and their properties; created new types of medical imaging and treatments; and provided new insight into the nature of matter and energy, and new methods to advance industry and security, among other wide-ranging applications.

Some Assembly Required: Scientists Piece Together the Largest U.S.-Based Dark Matter Experiment

Most of the remaining components needed to fully assemble an underground dark matter-search experiment called LUX-ZEPLIN (LZ) arrived at the project’s South Dakota home during a rush of deliveries in June. When complete, LZ will be the largest, most sensitive U.S.-based experiment yet that is designed to directly detect dark matter particles.

3 Sky Surveys Completed in Preparation for Dark Energy Spectroscopic Instrument

It took three sky surveys – conducted at telescopes in two continents, covering one-third of the visible sky, and requiring almost 1,000 observing nights – to prepare for a new project that will create the largest 3D map of the universe’s galaxies and glean new insights about the universe’s accelerating expansion.

What if Dark Matter is Lighter? Report Calls for Small Experiments to Broaden the Hunt

Theorized dark matter particles haven’t yet shown up where scientists had expected them. So Berkeley Lab researchers are now designing new and nimble experiments that can look for dark matter in previously unexplored ranges of particle mass and energy, and using previously untested methods.

A New Filter to Better Map the Dark Universe

To address messy measurements of the cosmic web that connects matter in the universe, researchers at Berkeley Lab developed a way to improve the accuracy and clarity of these measurements based on the stretching of the universe’s oldest light.

VIDEO: The Making of the Largest 3D Map of the Universe

In this video, Dark Energy Spectroscopic Instrument (DESI) project participants share their insight and excitement about the project and its potential for new and unexpected discoveries.

Dark Energy Instrument’s Lenses See the Night Sky for the First Time

On April 1 the dome of the Mayall Telescope near Tucson, Arizona, opened to the night sky, and starlight poured through the assembly of six large lenses that were carefully packaged and aligned for the Dark Energy Spectroscopic Instrument project, which is expected to provide the most precise measurement of the expansion of the universe, and new insight into dark energy.
