Baby Star Factory: JWST Unveils Sagittarius B2’s Hidden Star Birth
What JWST Reveals About a Cosmic Cloud The James Webb Space Telescope (JWST) has turned its infrared gaze toward Sagittarius B2 (Sgr B2), a colossal molecular cloud located near the center of our Milky Way. Although Sgr B2 contains only about 10% of the galactic center’s gas, it is a prolific cradle for star formation,…

MAGOS: Hot Cores in the LMC Reveal Subsolar Chemistry in Star Formation
Overview: MAGOS maps hot cores in a metal-poor neighbor The Magellanic Outflow And Chemistry Survey (MAGOS) targets the Large Magellanic Cloud (LMC) to explore how massive protostellar environments develop under subsolar metallicity. By surveying a sample of hot cores around 30 massive protostellar objects, the study investigates the chemical inventory, excitation conditions, and spatiotemporal evolution…

MAGOS: Hot Cores in the LMC — Exploring Subsolar Chemistry in the Large Magellanic Cloud
Introduction: A Subsolar Laboratory for Star Formation The MAGellanic Outflow And Chemistry Survey (MAGOS) opens a window into how massive stars form and how their surrounding chemistry unfolds under subsolar metallicity. Focusing on the Large Magellanic Cloud (LMC), a nearby dwarf galaxy with about half the Sun’s metallicity, the survey targets hot molecular cores around…

Gravity’s Tug-of-War: How Gravity Reorients Magnetic Fields in Star Clusters
Overview: A cosmic tug-of-war in star-forming clouds In the largest and most detailed survey to date, astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have captured new evidence about how gravity and magnetic fields shape the birth of massive stars. Focusing on regions where gas and dust densify to form protostars, researchers mapped the magnetic…
