The vast "sheet" of dark matter could explain why almost all of our galactic neighbors are running away from us.

Dark stars powered by dark matter may explain bright galaxies, massive black holes, and mysterious red objects in the early universe.

The six-year results from the Dark Energy Survey highlight unresolved tensions in standard cosmological theory.

Data from the James Webb Space Telescope was used to create the largest, highest resolution map of dark matter, just published in Nature Astronomy.

High-resolution images may help scientists understand the ‘gravitational scaffolding’ upon which the universe is built ...

Dark energy remains one of the most stubborn puzzles in modern science. Despite decades of observation and increasingly ...

These days when it’s cold out and gets dark early, it can be tempting to hole up at home and keep to ourselves.

The most ambitious attempt to do so was the Dark Energy Survey (DES), an international collaboration that scanned a huge ...

For decades, researchers have hoped to demystify what's known as dark matter, a material that comprises just over a quarter ...

Using observations from the James Webb Space Telescope in a patch of the sky covering almost three times the area of the full ...

Six years of Dark Energy Survey observations combine four cosmological probes to refine measurements of cosmic expansion, dark energy behavior, and matter clustering across billions of years.

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.
