Dark matter is so pervasive throughout galaxies that its presence explains the stability and motion of stars in systems such as the Milky Way. For example, current models indicate that our galaxy is ...

According to researchers, approximately 99 percent of this galaxy's total mass is dark matter.

Using the Hubble Space Telescope, astronomers have discovered what seems to be a galaxy that is the most heavily dominated by ...

Dark matter keeps getting blamed for the universe’s big patterns while staying stubbornly out of reach. You cannot see it, touch it, or capture it.

Scientists have just slashed the potential hiding spaces for dark matter particles. The LUX-ZEPLIN, or LZ, experiment has searched for and ruled out the existence of dark matter particles with a wide ...

NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe — and where the effect of dark ...

Earlier this week, science writer Paul Sutter covered a bold new study that leans toward so‑called “fuzzy” dark matter as the ...

Researchers at the Department of Energy's Oak Ridge National Laboratory are helping to pave a path for the eventual discovery of dark matter. With new approaches to measurement in the quantum realm, ...

Astronomers overwhelmingly agree a supermassive black hole anchors the Milky Way. But a new theoretical analysis explores a far more speculative possibility: not a black hole, but a dense knot of dark ...

Galaxies are far more than the sum of their stars. Long before stars even formed, dark matter clumped up and drew regular matter together with its gravity, providing the invisible scaffolding upon ...

Add Yahoo as a preferred source to see more of our stories on Google. Dark matter may have started hot and cooled during reheating after the Big Bang. (CREDIT: NASA / Goddard Space Flight Center ...

This NASA image shows two massive galaxy clusters previously captured by NASA's James Webb Space Telescope and Chandra X-ray Observatory, with areas of possible dark matter in blue. (NASA via AP) ...
