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

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, ...

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 ...

Our universe is a very strange place, but a new dark matter simulation seems to suggest that we live in a particularly strange area in it. According to a new paper published ...

Earlier this week, science writer Paul Sutter covered a bold new study that leans toward so‑called “fuzzy” dark matter as the hidden backbone of the cosmos. The research team compared three leading ...

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 ...

For nearly a century, astronomers have known that the universe is expanding. Most galaxies are carried outward with the flow ...

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 ...

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 ...
