The collision of two spiral galaxies appears as bright as a newborn star, as captured by the space telescope. James Webb.

The collision of the two galaxies, collectively known as Arp 220, resulted in an infrared glow comparable to the brightness of a trillion suns. In comparison, the luminosity of our galaxy (the Milky Way) is equivalent to about 10 billion suns.

The galactic collision Arp 200 is located 250 light-years away in the constellation of Opheus and is the brightest of the three collisions closest to Earth.

These two galaxies began colliding about 700 million years ago. As the gas and dust merged, this very bright glow seen in the center of the image was created, reminiscent of the birth of a star.

About 200 massive star clusters cluster in this dusty region, spanning about 5,000 light-years, or about 5% of the diameter of the Milky Way. However, in this “small” region there is as much gas as all the gas in our entire galaxy.

Previous radio telescope observations of this starry region have revealed about 100 remnants from supernova explosions that occurred in a region less than 500 light-years away.

The Hubble Space Telescope was able to detect the nuclei of colliding galaxies 1,200 light-years apart.

Each of the cores contains a rotating ring of stars, which emits dazzling infrared light. This Light was recorded by James Webb.

The “tails” of galaxies are depicted in blue, that is, the material removed from them due to gravity. Finally, orange and red streams of organic matter are seen in the merging galaxies.
