3-D Galaxy-mapping Project Enters Construction Phase

A 3-D sky-mapping project that will measure the light of millions of galaxies and explore the nature of dark energy has received approval to move forward with construction.

Dark Energy Measured with Record-Breaking Map of 1.2 Million Galaxies

A team of hundreds of physicists and astronomers, including those from Berkeley Lab, have announced results from the largest-ever, three-dimensional map of distant galaxies. The team constructed this map to make one of the most precise measurements yet of the dark energy currently driving the accelerated expansion of the Universe.

Researchers Gear Up Galaxy-seeking Robots for a Test Run

A prototype system that will test a planned array of 5,000 robots for a sky-mapping instrument is taking shape at Berkeley Lab. Dubbed ProtoDESI, the scaled-down, 10-robot system will run through a series of tests on a telescope in Arizona from August-September.

Radiation 101: DoseNet Delivers Environmental Data as an Educational Tool

DoseNet, a radiation-monitoring outreach project supported by Berkeley Lab and UC Berkeley, has a broad aim to inform and connect students and communities using science and data.

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.
