dark matter

We know which way the dark matter wind should blow. Now we just have to find it.

From Science, March 6, 2017: For more than a decade, multiple experiments have found an unexpected excess in the number of high-energy antielectrons, or positrons, in space. A team led by Fermilab’s Dan Hooper has shown that pulsars, not dark matter annihilation, can indeed produce most or all of the excess.

The PICO-60 dark matter bubble chamber experiment has produced a new dark matter limit after analysis of data from the most recent run.

Berkeley Lab is leading the construction of a mile-deep experiment that seeks to solve a science mystery.

New experiments will help astronomers uncover the sources that helped make the universe transparent.

Scientists furthered studies of the Higgs boson, neutrinos, dark matter, dark energy and cosmic inflation and continued the search for undiscovered particles, forces and principles.

Theorists think dark matter was forged in the hot aftermath of the Big Bang.

LUX-ZEPLIN (LZ), a next-generation dark matter detector that will be at least 100 times more sensitive than its predecessor, has cleared another approval milestone and is on schedule to begin its deep-underground hunt for theoretical particles, known as weakly interacting massive particles, in 2020.

What can our cosmic neighbors tell us about dark matter and the early universe?

How do scientists know what percentages of the universe are made up of dark matter and dark energy? Cosmologist Risa Wechsler of the Kavli Institute for Particle Astrophysics and Cosmology explains. Watch the 3-minute video.
