dark energy

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.

The Dark Energy Camera has 74 CCDs, which allows it to take high-resolution images. Reidar Hahn took this photograph, which is on display in the Fermilab Art Gallery as part of the “Art of Darkness” exhibit.

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. Signs indicate that they, like the objects found by the same team earlier this year, are likely dwarf satellite galaxies, the smallest and closest known form of galaxies.
