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 ...

An international collaboration, including Northwestern University, has reached a critical milestone in the search for dark matter, the mysterious substance that makes up about 85% of all matter in the ...

The team behind Europe's Euclid space telescope just published the world's most extensive simulation of the universe, which ...

The first time I heard about galaxies without dark matter, I was sitting in my very first graduate class at the University of São Paulo. A team had found a small, strange galaxy that appeared to ...

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, ...

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 ...

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 ...

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 ...
