Hunting for Dark Matter’s ‘Hidden Valley’

Kathryn Zurek realized a decade ago that we may be searching in the wrong places for clues to one of the universe’s greatest unsolved mysteries: dark matter. Despite making up an estimated 85 percent of the total mass of the universe, we haven’t yet figured out what it’s made of.

3 Knowns and 3 Unknowns about Dark Matter

While we can’t see dark matter, we are learning more about it. Here are three knowns and three unknowns about dark matter.

$40M to Establish New Observatory Probing Early Universe

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

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

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.

Supernova Hunting with Supercomputers

Berkeley researchers provide “roadmap” and tools for finding and studying Type Ia supernovae in their natural habitat

A Hot Start to the Origin of Life?

Researchers from Berkeley Lab and the University of Hawaii at Manoa have shown for the first time that cosmic hot spots, such as those near stars, could be excellent environments for the creation of molecular precursors to DNA.
