Where the Universe’s Normal Matter Really Lives: Beyond Planets and Stars
The mystery of the missing baryons When we gauge the universe, we count normal matter in the form of baryons—the protons, neutrons and electrons that make up atoms. In the local universe, most of these baryons don’t reside in planets, stars or galaxies. They’re dispersed much more broadly, lurking in the vast spaces between galaxies.…

Cosmic Filaments: One of the Universe’s Largest Spins
Unveiling a Giant Spin in the Cosmic Web In a groundbreaking discovery, astronomers have identified one of the Universe’s largest spinning structures: a colossal cosmic filament that appears to rotate as it threads through the cosmic web. Cosmic filaments are the vast, threadlike networks of galaxies and dark matter that form the scaffolding of the…

JWST Discovers Rapidly Feeding Black Hole in the Infant Universe
Unveiling an Early-Universe Powerhouse The James Webb Space Telescope (JWST) has revealed a remarkable glimpse into the infant universe: a supermassive black hole that is not only massive but actively devouring material at a staggering rate. Located in a galaxy formed within the first 570 million years after the Big Bang, this discovery challenges prevailing…

Pioneering JWST Observation Reveals Early Universe’s Rapidly Feeding Black Hole
Overview: A Glimpse into the Infant Universe In a remarkable achievement, the James Webb Space Telescope (JWST) has revealed a voraciously feeding and rapidly growing supermassive black hole from the universe’s infancy. Located at a time when the cosmos was merely about 570 million years old, this discovery offers a unique window into how supermassive…

Andromeda Quenching Satellites Before They Fall In
Introduction: A New Twist on Galaxy Growth For decades, astronomers have treated galaxy mergers as dramatic, defining moments in a galaxy’s life. The standard picture has been two or more systems meeting, merging, and leaving behind a larger, more massive structure with bursts of star formation. Yet new observations of the Andromeda Galaxy (M31) suggest…

The Superheated Star Factory: Y1’s Breakneck Birth Rate in the Early Cosmos
Unveiling a Superheated Star Factory In a remarkable glimpse into the universe’s youth, astronomers have identified a galaxy nicknamed Y1 that was churning out stars at an extraordinary pace just 800 million years after the Big Bang. Dubbed a “superheated star factory,” Y1 is birthing stars at roughly 180 times the rate of our Milky…
