Dark matter is not identified by the light it emits, but by its gravitational effects. The evidence developed from galaxies in the Coma Cluster a...
Cosmological simulations described by NASA suggest that dark matter moves slowly: cold models reproduce observed cosmic structures better than wa...
The Bullet Cluster offers a revealing comparison: the hot gas visible in X-rays appears separate from most of the mass inferred through gravitati...
Dark matter remains an elusive component of the universe. NASA reports that Webb data enabled an exceptionally high-resolution map—an observation...
NASA says that one of the most detailed, highest-resolution dark-matter maps yet made was produced with James Webb data. The advance improves obs...
