The National Science Foundation has awarded up to $21.4 million for the design of telescopes for CMB-S4, an international experiment that will study the cosmic microwave background and help us understand the beginning, history, and makeup of the universe. Berkeley Lab leads the project for DOE and also plays a lead role in technology development.

Listening to the Radio on the Far Side of the Moon
Researchers can use the radio-quiet far side of the moon to listen for a never-before-heard signal from the “Dark Ages” of the universe. The LuSEE-Night experiment will act as a pathfinder for future experiments, testing equipment and techniques in the harsh lunar environment.
When the First Stars Turned On: The Origins of the Universe
All stories start somewhere – even the incomprehensibly vast expanse above us has a beginning. Scientists have long studied the cosmos, searching for answers to the “how’s” and “why’s” of life, and that effort continues to this day. From concepts such as ‘Cosmic Dawn’ and ‘redshift,’ UNLV astronomer and computer scientist Paul La Plante focuses on topics that improve our understanding of where it all began.
First-of-its-kind measurement of the Universe’s expansion rate weighs in on a longstanding debate in physics and astronomy
A University of Minnesota Twin Cities-led team used a first-of-its-kind technique to measure the expansion rate of the Universe, providing insight that could help more accurately determine the Universe’s age and help physicists and astronomers better understand the cosmos.
SPIDER launches from Antarctica
A team of scientists including physicist Johanna Nagy at Washington University in St. Louis successfully launched a balloon-borne experiment studying the early universe on Dec. 21. The instrument, called SPIDER, was carried aloft by a scientific balloon from its launch pad in Antarctica.
Back to Antarctica with SPIDER
In the next few weeks, a team led by researchers at the University of Illinois at Urbana-Champaign will fly an instrument called SPIDER. They are looking for a pattern, or polarization, in the earliest light we can measure.
BICEP3 tightens the bounds on cosmic inflation
A new analysis of the South Pole-based telescope’s cosmic microwave background observations has all but ruled out several popular models of inflation.
DOE names six Argonne scientists to receive Early Career Research Program awards
Six Argonne scientists receive Department of Energy’s Early Career Research Program Awards.
Missing Baryons Found in Far-Out Reaches of Galactic Halos
Researchers have channeled the universe’s earliest light – a relic of the universe’s formation known as the cosmic microwave background – to solve a missing-matter mystery and learn new things about galaxy formation. Their work could also help us to better understand dark energy and test Einstein’s theory of general relativity by providing new details about the rate at which galaxies are moving toward us or away from us.
