New computer simulations suggest the first magnetic fields that emerged after the Big Bang were much weaker than expected — ...

There is a pattern found in nature. It is indeed the largest pattern there is. It is so vast that it spans the universe, filling up its observable volume. The pattern is made of individual units in ...

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 ...

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 ...

A research team from the University of California, Santa Cruz, have used the Oak Ridge Leadership Computing Facility's Summit supercomputer to run one of the most complete cosmological models yet to ...

York University and an international team of astrophysicists have made an ambitious attempt to simulate the formation of galaxies and cosmic large-scale structure throughout staggeringly large swaths ...

The JWST COSMOS-Web result, published in The Astrophysical Journal on May 6, 2026, traced the cosmic web by cataloguing 164,000 galaxies and placing them within the large-scale structure across cosmic ...

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.
