dark energy

From the DOE Office of Science, June 21, 2017: Dark Energy Survey Director Josh Frieman appears in this Office of Science article, which surveys research projects that will help us better understand the phenomenon that is accelerating the universe’s expansion.

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.

From Berkeley Lab, Aug. 9, 2016: DESI, the Dark Energy Spectroscopic Instrument, will measure light from 35 million galaxies to provide new clues about dark energy. Fermilab is a collaborator on the Berkeley Lab project.

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.

Nikolay Kuropatkin, Marty Murphy, Brian Nord and Brian Yanny created this photo of a galaxy, currently on display as part of the “Art of Darkness” exhibit in the Fermilab Art Gallery. A reception takes place on March 18 from 5-7 p.m.
