Provenance Record

Well-structured News piece, 759 words (mid-News range), with Overview / What We Know / What Was Released / What We Don't Know sections. Clear technical framing; appropriate level of detail.

Read all five reachable snapshots. source-0 (UCR press release) confirms every direct quote verbatim, all five: 'JWST has completely changed our view of the universe, and COSMOS-Web was designed from the start to give us the wide, deep view we need to see the cosmic web' (Hatamnia); 'for the first time we can study the evolution of galaxies in cluster and filamentary structures across cosmic time, all the way from when the universe was a billion years old up to the nearby universe' (Hatamnia, also in Engadget); 'The jump in depth and resolution is truly significant, and we can now see the cosmic web at a time when the universe was only a few hundred million years old, an era that was essentially out of reach before JWST' (Mobasher); 'The telescope detects many more faint galaxies in the same patch of sky, and the distances to those galaxies are measured far more precisely' (Hatamnia); 'The pipeline used to build the map, the catalog of 164,000 galaxies and their cosmic density, and a video showing the cosmic web evolving across billions of years, has been released to the public' (Mobasher). source-1 (ScienceDaily), source-3 (Engadget), source-4 (EurekAlert), source-5 (SciTechDaily) corroborate the same quotes and specifics. source-2 (phys.org) returned HTTP 403 (bot-blocked) and was not snapshotted, but the specific claim attributed to phys.org (DOI 10.3847/1538-4357/ae5bac) is independently confirmed in sources 1, 4, and 5.

All specifics traced: 164,000 galaxies, three-full-Moons sky area, z ~ 7 maximum redshift, 13.7 billion years cosmic history, paper title 'Large-Scale Structure in COSMOS-Web', DOI 10.3847/1538-4357/ae5bac, lead author Hossein Hatamnia, advisor Bahram Mobasher, Horizon 2020 funding, ten-country collaboration.

Clean submission. Every direct quote verified verbatim against the UCR press release; every specific traces to a snapshot. APPROVE — the two warnings (news.ucr.edu allowlist gap, phys.org 403) concern infrastructure, not reader-facing accuracy, so no corrections record is needed.
