Somewhere between the galaxy clusters that dot the observable universe, enormous threads of hot, diffuse gas stretch across ...

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 ...

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 ...

For decades, astronomers have known that galaxies are not scattered randomly through space. They cling to an enormous, mostly ...

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 ...

Astronomers have revealed the sharpest image ever captured of a filament in the cosmic web — the enormous hidden structure connecting galaxies across the Universe. The glowing strand stretches 3 ...

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.
