How Space Telescopes Work: From Hubble to James Webb

Have you ever wondered how a space telescope actually works?
In this video, we'll dive into the fascinating world of space telescopes, explaining how these incredible instruments help humanity explore the Universe. We'll uncover why telescopes use mirrors instead of lenses, how they overcome the limitations of Earth's atmosphere, and why they're positioned in space to capture clear, stunning images of galaxies and stars billions of light-years away.
You'll also discover:
• How telescopes act as cosmic time machines, allowing us to look back billions of years into the past.
• The differences between famous telescopes like Hubble and the groundbreaking James Webb Space Telescope.
• How images and data are transmitted from space telescopes back to Earth and transformed into the breathtaking images we know and love.
Join us as we journey through space, unraveling the mysteries of the cosmos and learning about the technology that makes it all possible!
