Perhaps the biggest question in astronomy right now is one that sounds simple: What is the universe made of? We know about protons, neutrons, and electrons, and we know these particles combine to ...

We may be more in the dark about dark matter than previously thought, according to a new analysis of distant galaxy clusters.

Like going to the eye doctor for a better pair of specs, astrophysicists are getting some upgraded lenses — both humanmade and natural — for a closer look at dark matter. An international team of ...

UB chemistry and physics researcher Eva Zurek is a key partner in the Center for Matter at Atomic Pressures (CMAP), a new effort led by the University of Rochester to study matter under extreme ...

A few decades ago, astronomers realized they had a problem: They could not find enough matter in the universe to account for all the space in between stars and galaxies. The missing mass begged the ...

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 ...

Dark matter is the elusive, invisible substance that appears to make up more than 80 percent of the total mass in the universe — far more than accounted for by the "regular" matter that makes up ...

Very distant galaxies have surprisingly little dark matter, the invisible stuff thought to make up the bulk of matter in the universe, new observations suggest. Stars in the outer regions of some ...

Gravity causes galaxies to rotate. Astronomers can study the speed of stars at different distances from the galactic center to look for evidence for dark matter or other new physics. The majority of ...

BUFFALO, N.Y. — University at Buffalo chemistry and physics researcher Eva Zurek is a key partner in the Center for Matter at Atomic Pressures (CMAP), a new effort led by the University of Rochester ...
