Dark matter, one of the Universe’s greatest mysteries, may have been born blazing hot instead of cold and sluggish as ...

Researchers from the University of Minnesota Twin Cities and Université Paris-Saclay have reopened one of cosmology’s oldest ...

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 and its impact on cosmology have puzzled physicists for nearly a century. At Perimeter Institute, two researchers are trying to better understand how one potential dark matter candidate, ...

For nearly a century, dark matter has been the invisible scaffolding of the universe, inferred from its gravitational pull but never directly seen. Now a cluster of independent results, from subtle ...

The Perseus cluster is a vast swirl of thousands of galaxies, all bound together by gravity. Famed for its unbelievable size — containing the mass of some 600 trillion suns — it also has a reputation ...

For decades, dark matter has been the universe’s most stubborn mystery, silently shaping galaxies while refusing to show itself to our instruments. Now a bold new claim from a Japanese astronomer ...

Dark matter is an elusive type of matter that does not emit, reflect or absorb light, yet is estimated to account for most of the universe's mass. Over the past decades, many physicists worldwide have ...

Dark matter makes up most of the mass in galaxies and galaxy clusters. In fact, scientists estimate that ordinary matter makes up only about 5% of the universe, while dark matter makes up about 27%.

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 ...
