Galaxies are far more than the sum of their stars. Long before stars even formed, dark matter clumped up and drew regular matter together with its gravity, providing the invisible scaffolding upon ...

A galaxy made almost entirely of dark matter, an elusive form of matter that doesn’t interact with light, was spotted by Hubble 250 million light-years from Earth.

Physicists are quietly rolling out a new generation of simulation codes that promise to do more than crunch numbers. By weaving together quantum theory, astrophysical data and high precision sensors, ...

A groundbreaking computational physics framework has demonstrated that the three-dimensional fabric of the universe can be generated from scratch using a simple algorithm with exactly zero free ...

With less than 20 percent of all physical matter made from visible stuff—from stars and planets, to the kitchen sink—astronomers continue to hypothesize what form the invisible majority of the ...

Add Yahoo as a preferred source to see more of our stories on Google. The Galactic Center Excess, shines in high-energy gamma rays that can’t be explained by ordinary astrophysical processes. Its ...

In this visualization, each dot represents a gas parcel with a mass approximately 1,000 times that of the Sun in the simulation of the cosmic Dark Ages. The left and right panels compare the cold and ...

The James Webb Space Telescope (JWST) has already begun to unravel the mysteries of the universe, offering new insights into phenomena like galaxy formation. One area where JWST is making particularly ...

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 ...

On a clear night, the Milky Way and the Andromeda galaxy look like close neighbors. In space, they really are.

This is interesting of course, but the article suffers from problems. Besides the missing article link, the linked spiral arm dynamical mass excess observations are not explained by dark matter as it ...

Faint radio signals from the early Universe, soon detectable by Moon missions, may reveal how dark matter shaped gas cooling and clumping in the cosmic Dark Ages. Ordinary matter, which makes up the ...
