Arp 220, an ultra-luminous infrared galaxy (ULIRG) with a luminosity literally greater than that of a trillion suns. Arp 220 glows brightest in infrared light, Webb's object is the result of a collision between 2 spiral galaxies that began about 700m years ago, sparking a huge burst of star formation. The light from this star formation is shrouded in dust, which Webb can see through with its infrared vision. Located 250 million light-years away, Arp 220 is both the nearest ULIRG and the brightest of the 3 galactic mergers closest to : NASA
