Extended components of little red dots in the rest-frame optical
Furtak, L. J. et al. JWST UNCOVER: extremely red and compact object at zphot = 7.6 triply imaged…
Cosmic plasma was supposed to rule out dark photons. Simulations say otherwise
A major limit on dark photon dark matter may be far weaker because early-universe plasma stops absorbing energy…
Vigorous turbulence driven by quasar-mode feedback in a cluster core
The X-Ray Imaging and Spectroscopy Mission (XRISM)1 is the successor to the Hitomi X-ray observatory2, which ceased operations…
Dark matter may be naturally tuned to a hidden fifth dimension
Dark matter appears to hold galaxies together, yet it has never shown itself directly. A new theory suggests…
New study reveals how dark matter formed shortly after the Big Bang
Dark matter may not have needed a calm, cold start to help build the universe. For decades, that…
Hubble has spotted ‘impossible’ light in deep space, and scientists are trying to explain where it came from
Astronomers have detected light from a tiny but powerful galaxy that existed when the universe was still emerging…
James Webb Space Telescope Spots Six Galaxies Merging Into One 12 Billion Years Ago
The James Webb Space Telescope has caught six massive galaxies in the act of colliding and merging into…
Hubble Catches Tiny Galaxy Clearing Cosmic Fog Just 1.4 Billion Years After the Big Bang
A small, ferociously star-forming galaxy observed by NASA’s Hubble Space Telescope has given astronomers their closest look yet…
Scientists use Einstein’s equations to reveal what came before the Big Bang
Some of the hardest questions in cosmology begin where the usual math gives up. Push Einstein’s theory far…
Astronomers Trace Elusive High-Energy Neutrino to Star-Forming Galaxy in Early Universe
JCMT0402-0424, a dusty starburst galaxy around 11 billion light-years away, is the strongest candidate yet for the source…
NASA’s James Webb Space Telescope Spots a Hidden ‘Galaxy Killer’ Lurking in the Early Universe
The James Webb Space Telescope (JWST) has revealed a cosmic catastrophe, as winds extinguished a star-forming galaxy in…
Galaxy-killing wind may explain why giant galaxies died so early
A massive galaxy in the early universe seems to be growing itself toward ruin. While it churns out…
