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

Computer simulations carried out by astronomers from the University of Groningen in collaboration with researchers from ...

A series of high-resolution simulations has revealed a striking new perspective on theMilky Way’s position in the cosmos. Far ...

The Milky Way — and in fact our entire galactic neighborhood known as the Local Group — appear to be lodged in a vast, ...

A new simulation tool lets scientists explore whether self-interacting dark matter could reshape galaxies from the inside out.

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 ...

It’s an open secret in astronomy that, practically wherever the James Webb Space Telescope (JWST) looks in the sky, a vast, clump-filled mist fills its view. Think of dark matter as scaffolding for ...

For many years, scientists have tried to understand how the Milky Way is positioned in space, and how it moves together with ...

Astronomers have uncovered what looks like the sharpest evidence so far that a dense clump of dark matter is lurking ...

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 ...

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 ...
