James Webb Telescope Uncovers 'Cosmic Owl': A Rare Galactic Collision 11 Billion Light-Years Away
  • The James Webb Space Telescope has captured images of a rare collision between two ring galaxies, an event that has been interpreted differently by two research teams, providing new insights into galaxy formation and evolution.

  • This collision, approximately 11 billion light-years away, has produced a striking structure dubbed the 'Cosmic Owl,' which features two active galactic nuclei resembling owl's eyes and a star-forming region that looks like a beak.

  • The Cosmic Owl serves as a natural laboratory for studying galaxy formation, black hole activity, and star creation, offering valuable data on how galaxies rapidly build stellar mass in the universe's early history.

  • The merger's collision zone is a crucial mechanism for rapid and efficient star formation, with radio jets from one galaxy's black hole further compressing gas and fueling stellar birth.

  • A second research team identified the same merger as the 'Infinity Galaxy,' which was studied using Keck spectroscopy, VLA radio data, and Chandra X-ray observations, revealing an actively accreting supermassive black hole.

  • The colliding galaxies are relatively small, about 26,000 light-years in diameter, and are in the early stages of merging, with the collision estimated to have occurred just 38 million years ago.

  • The collision has triggered a massive starburst in the 'beak' region, with shock waves and molecular gas compression fueling intense star formation.

  • The 'Cosmic Owl' features two active galactic nuclei resembling owl’s eyes, each harboring supermassive black holes over 10 million times the Sun's mass, and a star-forming region that looks like an owl’s beak.

  • This structure produces an intense shockwave, illustrating how galactic collisions and radio jets contribute to galaxy evolution and star formation.

  • This discovery highlights the significant role of galactic collisions and radio jets in star formation and galaxy development, adding to other unusual phenomena observed by JWST.

  • The merger, observed using Webb’s COSMOS-Web, PRIMER, COSMOS-3D, and ALMA in Chile, was identified as the 'Cosmic Owl' with active galactic nuclei, showcasing the telescope’s advanced capabilities.
