In addition to observing specific objects such as galaxies and distant planets here in our solar system, the James Webb Space Telescope is also used to perform large-scale surveys of parts of the sky. These surveys look at large swathes of the sky to identify important targets such as very distant and very ancient galaxies, … Read more
