Dark matter makes up roughly 85% of the stuff in our universe. It doesn’t glow, it doesn’t reflect light, and we can’t even see it. We only know it’s there because its massive gravity holds galaxies ...

Dark matter doesn’t emit, absorb, or reflect light. It’s invisible but supposedly makes up 85% of the universe’s mass.

Now physicists from the University of Washington are taking a big swing at answering that question. All matter exerts gravitational force. The more mass the object has, the greater the force. Yet, a ...

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 ...

Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to their supercomputer simulations. We know it's real because its mass ...

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

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary matter. These characteristics make it impossible to detect using ...

Scientists still don’t know what dark matter is. It doesn’t interact with any electromagnetic force or regular matter except through the gravitational force it exerts. A research team has a come up ...

Earlier this week, science writer Paul Sutter covered a bold new study that leans toward so‑called “fuzzy” dark matter as the hidden backbone of the cosmos. The research team compared three leading ...
