The video explores the history of space exploration, starting with the launch of Sputnik in 1957. It discusses ancient astronomy, the heliocentric model proposed by Copernicus, and Galileo's contributions using telescopes. The video explains the types of telescopes, refractor and reflector, and their uses. It highlights the challenges faced by ground-based telescopes due to atmospheric interference and introduces the Hubble Space Telescope, detailing its development, challenges, and contributions to astronomy. The video encourages viewers to explore space with their own telescopes.
