Atomic clocks on Earth could reveal secrets about dark matter across the universe
By Robert Lea published
Using atomic clocks could help bring cosmology and astrophysics "down to Earth" by allowing scientists to investigate the mystery of dark matter in the lab.

We still don't know what dark matter is, but here's what it's not
By Monisha Ravisetti published
An experimental detector can now rule out dark matter particles down to about a fifth of a proton's mass.

A nearby supernova could reveal the secret lives of ghostly neutrinos. Here's how.
By Keith Cooper published
By modeling the neutrinos from a supernova as an exotic kind of fluid moving at nearly the speed of light, researchers are searching for signs of how neutrinos can interact with each other.

25 years after its discovery, dark energy remains frustratingly elusive
By Paul Sutter published
While there are hints that dark energy may be 'phantom,' its true nature remains frustratingly elusive, a new study reports.

Researchers dig deep underground in hopes of finally observing dark matter
By Hugh Lippincott published
Physicists like me don't fully understand what makes up "dark matter." Deep beneath South Dakota, we're trying to change that.

What is dark matter?
By Nola Taylor Tillman last updated
Reference Roughly 80% of the mass of the universe is made up of dark matter, a material that scientists cannot directly observe. So why do scientists think it dominates?

We can measure dark energy across the universe in our own cosmic backyard
By Paul Sutter published
Researchers have found a new way to measure dark energy — the mysterious force that is causing the expansion of the entire universe to accelerate — using data from our own cosmic backyard.
