NASA | Webb Telescope Planetary Studies Web Feature

The video explores the James Webb Space Telescope's role in studying exoplanets, atmospheric gases, and dusty discs. It delves into the history of our solar system, focusing on small bodies like asteroids and comets. The video also examines the outer planets and their moons, with a particular interest in Titan. Seasonal changes on Uranus and Neptune are discussed, as well as the Kuiper Belt's significance in understanding planetary systems. The telescope's capabilities allow for a deeper comparison of our solar system with others, enhancing our knowledge of planetary formation and evolution.

What is one of the primary goals of the James Webb Space Telescope?
