In the close Universe, the distance typically is a predictor of speed: more distant galaxies recede more rapidly. Another rule around the Milky Way has long been strangely compliant, however. Most of ...

A flat plane of dark matter beyond the Local Group may explain why nearby galaxies move away from us instead of falling ...

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

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

From galaxies to the Sun, new research explains how turbulent motion can produce large-scale magnetic fields that remain ...

The discovery reinforces established theories about space. There could be many more satellite galaxies orbiting the Milky Way than previously thought or observed, according to astronomers. As many as ...

As gas falls toward a black hole, it heats up and shines. If the glow becomes intense enough, it can push incoming gas away. Astronomers call this balancing point the Eddington limit, and for decades ...

The consortium running the European Space Agency's (ESA) Euclid mission has published the most extensive simulation of the cosmos to date. The modeling was based on algorithms developed by UZH ...

"The knowledge of these will ultimately help us understand the formation of the first stars and planets and how our own Milky ...

Is it time to rethink one of physics’ fundamental forces?
