NASA | JWST Feature - Galaxy Evolution

The video explores how observing space allows us to look back in time, as light from distant galaxies takes millions of years to reach us. The Hubble Space Telescope has provided deep views into the universe, revealing galaxies as they were billions of years ago. These early galaxies were small and grew through mergers, leading to the formation of larger galaxies and star formation. To see even further back, the James Webb Space Telescope is being developed, with advanced capabilities to observe the most distant galaxies in the infrared spectrum.
