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 ...

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 ...

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

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 ...

Researchers may have identified what could be a compelling clue in the ongoing hunt to prove the existence of dark matter. A mysterious diffuse glow of gamma rays near the center of the Milky Way has ...

Add Yahoo as a preferred source to see more of our stories on Google. A bright band of diffuse gamma ray glow along the map's center, which marks the central plane of the Milky Way galaxy, is seen in ...

Dark matter may be invisible, but scientists are getting closer to understanding whether it follows the same rules as everything we can see. By comparing how galaxies move through cosmic gravity wells ...

Scientists have long been puzzled by dark matter, an elusive substance that makes up about 27% of the universe. Recent breakthroughs in research are shedding light on its mysterious nature, ...

An artistic illustration of the mechanism proposed by Professor Stefano Profumo where quantum effects near the rapidly expanding cosmic horizon after the Big Bang gravitationally generate dark matter ...

For decades, the prevailing cosmological model has placed dark matter and dark energy at the center of our understanding of the universe’s structure and evolution. These invisible components were ...

Astronomers have found the strongest evidence yet for the existence of dark stars, a type of enormous star in the early universe that is partially powered by dark matter. If confirmed, these ...

Dark matter is a real pain in the neck. The term dark matter itself refers to a hypothetical substance that seems to solely interact with the rest of the universe via gravity and to serve as the ...
