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 ...

In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark ...

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.

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 ...

A groundbreaking new study, recently published on arXiv, challenges one of the most fundamental assumptions in cosmology: that dark matter remains constant over time. For decades, scientists have ...

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 Anglo-USA team behind the study named them dark dwarfs. Not because they are dark bodies—on the contrary—but because of their special link with dark matter, one of the most central topics in ...

Scientists are shining a brighter light on dark matter thanks to a new high-resolution map, unveiling the invisible material that shapes everything we see. Using James Webb Space Telescope’s (JWST) ...

Gamma-ray intensity map excluding components other than the halo, spanning approximately 100 degrees in the direction of the Galactic center. The horizontal gray bar in the central region corresponds ...
