"Webb Telescope Captures Epic Cosmic Collision and Glowing Starburst"

TL;DR Summary
The James Webb Space Telescope captured a stunning image of Arp 220, an ultra-luminous infrared galaxy formed by the merging of two spiral galaxies. The collision sparked a massive star formation, with about 200 huge star clusters in a compact, dusty region containing gas equal to the entire Milky Way. The telescope revealed the parent galaxies’ cores, each with a rotating, star-forming ring responsible for the striking infrared light. The image also shows faint tidal tails and organic material as evidence of the ongoing galactic merger.
