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 ...

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, ...

Giant worlds beyond the Solar System could be the probe we need to figure out how dark matter manifests in the Universe. According to a new study, one particular dark matter model could see the ...

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 ...

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 ...

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.

Dark matter remains one of the biggest mysteries in fundamental physics. Many theoretical proposals (axions, WIMPs) and 40 years of extensive experimental searches have failed to provide any ...

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 ...

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 ...

The Milky Way — and in fact our entire galactic neighborhood known as the Local Group — appear to be lodged in a vast, extended “sheet” of dark matter flanked on each side by cosmic voids, new ...

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 ...
