Earlier this year, the Dark Energy Spectroscopic Instrument (DESI) completed observations that mapped 47 million galaxies across 11 billion light-years, allowing astronomers to better evaluate the ...

Introduction]'The universe is roughly uniform in its distribution of stars and galaxies when viewed on a sufficiently large ...

Gamma-ray bursts (GRBs) are the most energetic events ever observed in the universe. These powerful outbursts can shine a quintillion (10 18) times brighter than the sun. Since they were first ...

Cosmological accretion shocks created during the formation of galaxy clusters are a ubiquitous phenomenon all around the universe. These shocks and their features are intimately related with the ...

If you think a galaxy is big, compare it to the size of the universe: it's just a tiny dot which, together with a huge number of other tiny dots, forms clusters that aggregate into superclusters, ...

The Big Bang is often presented as if science has completely solved the beginning of the universe: everything started in one ...

The Universe on the largest scales exhibits a complex network of filaments, sheets and voids that together form the cosmic web. This web is generated by the gravitational growth of primordial density ...

A massive structure detected in the distant Universe is defying our understanding of how the Universe evolved. In 2024, astronomers found a giant, almost perfect ring of galaxies, some 1.3 billion ...

Carnegie Mellon University Physics Professor Colin Morningstar is part of a national research team awarded a Phase II grant from the U.S. Department of Energy's Genesis Mission. The project will use ...

The Simons Collaboration on Learning the Universe (LtU) brings together scientists from cosmology, galaxy formation, statistics, and machine learning with a shared ambition: to build a rigorous, ...

Look up on a dark night and the stars seem scattered at random. Step back in scale, though, and the Universe looks nothing like a loose dusting. On its largest stretches, matter forms a vast web.

An international team of scientists from the Euclid Consortium has unveiled the most detailed virtual model of the Universe to date, simulating more than 3.4 billion galaxies. The synthetic dataset, ...
