Astrophysics and cosmology

Researchers hope that the new experiment will shine light on how elementary neutrinos morph from one type into another.

It’s in the air we breathe, but it’s not so easy to get ahold of 10 metric tons of xenon in its liquid form for the LUX-ZEPLIN dark matter experiment.

SLAC is ramping up its efforts to understand neutrinos – elusive fundamental particles whose properties may help researchers solve a number of cosmic mysteries.

The DOE has approved the project’s scientific scope, schedule and funding. SLAC researchers are among the 200 physicists and astronomers who make up the international DESI Collaboration.

How can we figure out when the universe began?

Scientists on the Dark Energy Survey, using one of the world’s most powerful digital cameras, have discovered eight more faint celestial objects hovering near our Milky Way galaxy.

Observations of this kind could lead scientists to the source of ultra-high-energy cosmic rays.

Our universe could be just one small piece of a bubbling multiverse.

Dark energy is everywhere. It will determine the fate of our universe. And we still have no idea what it is.
