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 ...

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 ...

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

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 ...

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

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 ...

All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the ...

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