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

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 ...

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

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 ...

Earlier this week, science writer Paul Sutter covered a bold new study that leans toward so‑called “fuzzy” dark matter as the ...

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 ...

Astronomers have uncovered evidence that the Milky Way is not drifting through space alone but is embedded in a vast, flat structure of dark matter stretching tens of millions of light-years. The ...

At the center of our galaxy, there’s a mysterious, diffuse glow given off by gamma rays — powerful radiation usually emitted by high-energy objects such as rapidly rotating or exploding stars. NASA’s ...

Dark energy is responsible for the expansion of the Universe, but its true nature is still a subject of much debate. Computer simulations based on the latest astronomical data enable scientists to ...

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 ...

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 ...
