Astronomers used James Webb Space Telescope data to determine the density of the universe's most mysterious "stuff." ...

Dark matter keeps getting blamed for the universe’s big patterns while staying stubbornly out of reach. You cannot see it, touch it, or capture it.

Transformative discoveries in cosmology are unfolding at Princeton as researchers explore the universe’s large-scale structure, including galaxies, dark matter, and dark energy. Professor of ...

Dynamical friction. The panels depict sparse areas of the universe with dark colour and dense areas with light colour. The upper panels show the density around a galaxy if the galaxy's gravity bends ...

By comparing this new map with what's known as the cosmic microwave background (CMB), scientists have been able to roughly verify the distribution and density of matter in the universe, providing more ...

The map, assembled with data from the Gaia spacecraft, shows how the spread of dark matter across space matches that described by the Cosmic Microwave Background. When you purchase through links on ...
