The Dark Energy Survey’s art show offers a glimpse of the expanding universe.

Before the Dark Energy Survey began in August 2013, scientists spent months testing the Dark Energy Camera, putting it through its paces. Now, catalogs of galaxies and stars derived from the data collected during the Science Verification season have been released to the public.

Let yourself be pulled into the weird world of black holes.

A recent uptick in the discovery of the smallest, oldest galaxies benefits studies of dark matter, galaxy formation and the evolution of the universe.

Pranav Sivakumar, a student at the Illinois Math and Science Academy, was recently recognized by President Barack Obama at White House Astronomy Night. Fermilab Ask-a-Scientist and Saturday Morning Physics talks were significant influences in his decision to pursue science.

Scientist Marcelle Soares-Santos talks about Brazil, neutron stars and a love of discovery.

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.

A unique experiment at the U.S. Department of Energy’s Fermi National Accelerator Laboratory called the Holometer has started collecting data that will answer some mind-bending questions about our universe — including whether we live in a hologram.

With its second year under way, the Dark Energy Survey team posts highlights and prepares to release images from its first year

On Aug. 31, the Dark Energy Survey (DES) officially began. Scientists on the survey team will systematically map one-eighth of the sky (5000 square degrees) in unprecedented detail. The start of the survey is the culmination of 10 years of planning, building and testing by scientists from 25 institutions in six countries.
