James Webb Telescope captures stunning image of trillion-sun merging galaxies.

NASA's James Webb Space Telescope has captured a stunning image of the merging galaxies known as Arp 220, which are spirals like the Milky Way and have similar tails swirling in their outskirts. The galaxies began merging 700 million years ago, triggering intense star formation, and most of it was concentrated in their dusty central regions. Over 200 star clusters are packed in an area just 5,000 light-years across, and Arp 220's central star-forming ring shines brilliantly, its light seen as six spikes ejecting out in Webb's image. The object's light is equivalent to "more than a trillion suns," according to the image description.
