Astronomers have revealed the sharpest image ever captured of a filament in the cosmic web — the enormous hidden structure ...

Somewhere beyond the light of any single galaxy, a vast architecture of gas and dark matter stretches across the observable ...

Cold gas does not look dramatic at first glance. Neither does dust. Yet those two quiet ingredients sit at the center of a new effort to build a far more realistic picture of how galaxies formed. They ...

The magnetic fields lacing through galaxy clusters and cosmic filaments have no business being there. The early universe was ...

Long before galaxies sparkled in the sky or stars took shape, invisible forces stirred in the early Universe. One of those forces—magnetism—emerged in ways scientists are only now beginning to ...

Scientists create the most detailed and accurate simulation ever produced of the first billion years of the universe. The CoDa III simulation shows galaxies forming in the early universe along the ...

Once dismissed as empty expanses between galaxies, cosmic voids are becoming one of the most promising tools for probing the ...

A simulation of the ‘cosmic web’, the vast network of threads and filaments that extends throughout the Universe. Stars, galaxies, and galaxy clusters spring to life in the densest knots of this web, ...

For the first time, astronomers have caught a glimpse of shock waves rippling along strands of the cosmic web — the enormous tangle of galaxies, gas and dark matter that fills the observable universe.

Scientists used some of the most advanced plasma simulations ever created to uncover how the universe builds enormous magnetic fields out of turbulence. The discovery could reshape our understanding ...
