🔭 Quasar-Triggered Star Formation Shutdown * Why in the news? 📍 Discovery : The Inter-University Centre for Astronomy and Astrophysics ( IUCAA), Pune & international team confirm that quasars halt star formation when galaxies collide. 🌌 Observations : Using VLT & ALMA telescopes , scientists found that quasar radiation strips interstellar gas , preventing star formation. 📍 Key Telescopes Used in IUCAA’s Research Very Large Telescope (VLT) —Operated by the European Southern Observatory (ESO) in Chile, VLT is one of the most advanced optical telescopes. It is used to study distant galaxies, quasars, and cosmic phenomena . Atacama Large Millimeter/Submillimeter Array (ALMA)— A powerful radio telescope in Chile, ALMA helps observe cold interstellar gas, star formation, and early universe structures . 📍 Recent Discovery: Quasar Disrupting Star Formation IUCAA researchers, in collaboration with an international team, used VLT and ALMA to observe a galaxy inte...
