A brilliant starburst feature shines in the latest image taken by the James Webb Space Telescope. The space observatory captured a bright burst of star formation triggered by two spiral galaxies crashing into one another. The colliding galaxies, known collectively as Arp 220, generated an infrared glow that contains the light of more than 1 trillion suns. For comparison, the Milky Way galaxy has a luminosity that is the equivalent of about 10 billion suns.
There are around 200 massive star clusters contained in a dusty region that stretches 5,000 light-years across, which is about 5% of the Milky Way’s diameter. Yet there is enough gas in this small region, astronomically speaking, to replace all of the gas in the entire Milky Way. Previous observations of this star-packed region from other telescopes have observed different features.
