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 ...

Using the James Webb Space Telescope, astronomers have created the most detailed map of the cosmic web ever.

A new JCAP study tests an “emulator” to reconstruct the large-scale structure of the cosmos If you think a galaxy is big, compare it to the size of the Universe: it’s just a tiny dot which, together ...

The largest known structure in the Universe may be even larger than the large we thought it was. A re-examination of the distribution of powerful space explosions suggests that the Hercules-Corona ...

The largest sample of galaxy groups ever detected has been presented by a team of international astronomers using data from the James Webb Space Telescope (JWST) in an area of the sky called COSMOS ...

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 ...

New telescopes are challenging the idea that the cosmic web fades into a uniform, directionless distribution. It may be ...

The large-scale structure of the Universe arises from the gravitational amplification of primordial fluctuations, producing a cosmic web of galaxies, filaments, clusters and voids. At sufficiently ...

A team of astrophysicists has just published in Nature a finding that calls into question one of the pillars of modern ...

A study based on 47 million galaxies found that the cosmic web retains patterns on enormous scales, which could force a ...
