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 ...
A simulation of the cosmic sheet as seen from the side, with voids above and below. (Wempe et al., Nat. Astron., 2026) The Milky Way isn't just drifting through a giant void in space untethered, but ...

Study suggests the Milky Way sits in a sheet-like "pancake" of dark matter
An international research team has found that the Milky Way and its galactic neighbors appear to sit inside a vast, flat concentration of dark matter, a structure stretching roughly 10 megaparsecs and ...

Astronomers spot colossal cosmic sheet wrapped around the Milky Way
A team of astronomers led by researchers at the University of Groningen has identified a colossal sheet of dark matter and ...
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 ...
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 ...
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 groundbreaking computational physics framework has demonstrated that the three-dimensional fabric of the universe can be generated from scratch using a simple algorithm with exactly zero free ...
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 ...
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 ...
