JWST captures breathtaking images of colliding galaxies.

NASA's James Webb Space Telescope has captured a stunning image of the moment two spiral galaxies, collectively called Arp 220, collided 250 million light-years from Earth. The collision began about 700 million years ago and sparked an enormous burst of star formation, emitting more light than one trillion suns. Arp 220 is the nearest example of an ultra-luminous infrared galaxy and glows brightest in infrared light, making it an ideal target for Webb. The $10 billion observatory is designed to detect light from the earliest stars and galaxies and observe the sources of stars, exoplanets, and even the moons and planets of our solar system.
