Fermilab is an enduring source of strength for the US contribution to scientific research world wide.

Scientists exploring data collected by the Fermilab-constructed, Chilean-based Dark Energy Camera (DECam) discovered 20 satellite galaxies of the Milky Way, nearly doubling the number previously known and adding to those identified by the earlier Sloan Digital Sky Survey, another project where Fermilab played a key role. These tiny satellite galaxies can contain hundreds of times more dark matter than normal matter. Whether the mysterious dark matter turns out to be axions, weakly interacting massive particles or something else, DECam has proven itself to be a powerful new tool for the dark matter community.

Fermi National Accelerator Laboratory (Fermilab), located just outside Batavia, Illinois, near Chicago, is a US Department of Energy national laboratory specializing in high-energy particle physics. Fermilab is America’s premier laboratory for particle physics and accelerator research, funded by the U.S. Department of Energy. Thousands of scientists from universities and laboratories around the world
collaborate at Fermilab on experiments at the frontiers of discovery.
