Webb Captures the Spectacular Galactic Merger Arp 220

A stunning smash-up of two spiral galaxies shines in infrared with the light of more than a trillion suns. Collectively called Arp 220, the colliding galaxies ignited a tremendous burst of star birth. Each of the combining galactic cores is encircled by a rotating, star-forming ring blasting out the glaring light that Webb captured in infrared. This brilliant light creates a prominent, spiked, starburst feature. Credits: NASA, ESA, CSA, STScI, Alyssa Pagan (STScI)
