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 ...

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 ...

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, one of the Universe’s greatest mysteries, may have been born blazing hot instead of cold and sluggish as scientists long believed. New research shows that dark matter particles could have ...

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 ...

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 ...

Now is a surreal time to be a dark matter researcher. Even as research funding is being cut by governments around the world, dark matter remains one of the biggest and most exciting open problems in ...

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, ...

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 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 ...

A puzzling ultraviolet light seen across the Milky Way could come from the destruction of nuggets of dark matter, the mysterious stuff that makes up around a quarter of the matter and energy in the ...

We may have seen the first hints of strange stars powered by dark matter. These so-called dark stars could explain several of the most mysterious objects in the universe, while also giving us hints ...
