JWST Reveals Black Hole Slowly Starving Pablo’s Galaxy
Introduction: A cosmic slow burn In a striking parallel to a gripping crime saga, astronomers using the James Webb Space Telescope (JWST) have uncovered how a young galaxy—nicknamed Pablo’s Galaxy in recent studies—was slowly starved of new stars. The central supermassive black hole grew voracious, siphoning gas and suppressing stellar birth in a process that…

Ancient Dead Galaxy: How a Supermassive Black Hole Starved the Early Universe
Ancient Dead Galaxy Reveals a Cosmic Power Unlike Any Other In a groundbreaking discovery, researchers using the James Webb Space Telescope (JWST) have identified one of the earliest known dead galaxies. The object, located in the young universe, appears to have halted star formation long before many of its peers, providing critical clues about how…

Ancient Dead Galaxy Revealed: Starvation Fuelled by a Supermassive Black Hole
Introduction: A Glimpse into the Early Universe’s Quiet Giants In a breakthrough study, researchers using the James Webb Space Telescope (JWST) have identified what may be among the earliest known “dead” galaxies. These ancient systems, which stopped forming stars very early in cosmic history, offer crucial clues about how massive galaxies halt their growth. The…

Andromeda’s Quiet Quenching: How its Satellites Fade Before Infall
Overview: A New Twist on Galaxy Growth For decades, astronomers have tracked how giant galaxies grow by consuming smaller companions. The Milky Way’s ongoing serenade with the Large and Small Magellanic Clouds—evidenced by the Magellanic Stream of gas trailing behind—has long served as a cornerstone example. But recent observations of our neighboring Andromeda Galaxy (M31)…

Andromeda Galaxy Quenches Its Satellite Galaxies Long Before They Fall In
Overview: A New Twist in Galaxy Growth Astronomers have uncovered evidence that the Andromeda Galaxy, our nearest spiral neighbor, can suppress star formation in its satellite galaxies long before they are captured in a full merger. This quenching process, which halts the birth of new stars, helps explain why some dwarf companions around large spirals…
