Telescope Evolution and the James Webb Space Telescope

The video explores the evolution of telescopes, from early designs using lenses to modern telescopes like the Hubble and the James Webb Space Telescope. It highlights the challenges of observing distant objects due to atmospheric interference and the advancements made with space-based telescopes. The James Webb Telescope, set to launch in 2018, aims to explore the infrared spectrum, offering insights into exoplanet atmospheres, galaxy compositions, and the early universe.
