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

Astronomers around the world are looking for visible sources of gravitational waves.

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

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.

A batch of newly discovered satellite dwarf galaxies orbiting the Milky Way should help scientists better grasp the evolution of the universe while also honing in on dark matter's identity.

Dark Energy Survey scientists have released a detailed map of dark matter – crucial information for a better understanding of galaxy formation and dark energy.

Reports by groups including Dark Energy Survey and Large Area Telescope scientists may provide new clues about the properties of mysterious dark matter.

In September, DES will make data collected in its first season freely available to researchers.

A team of scientists generated a giant cosmic simulation—and now they're giving it away.

Step on a scale and you’ll get a quick measure of your weight. Weighing galaxy clusters, groups of hundreds or thousands of galaxies bound together by gravity, isn’t so easy. But scientists have many ways to do it.

The Particle Physics Project Prioritization Panel’s report, released today, recommends a strategic path forward for US particle physics.

The Particle Physics Project Prioritization Panel’s recommendations will set the course for the future of particle physics in the United States.
