Colliding Galaxies: James Webb Space Telescope Science Feature

About this video
Duration: 3 minutes, 58 seconds

Galaxies were built up through collisions and mergers, but this process isn't over – and our own Milky Way galaxy provides a prime example of how it continues today.

Deep surveys by the James Webb Space Telescope will capture the full panorama of galaxy evolution, from the earliest dwarf galaxies that formed to the familiar galaxies we see today. The Webb Telescope will help us understand how the shape, structure and chemical content of galaxies change over the sweep of cosmic history.
