Telescopes

The video tutorial explains the evolution and function of telescopes, starting with the first optical telescopes in 1608, which used refraction to magnify images. It highlights Galileo's use of refracting telescopes and the development of reflecting telescopes by 1616, improved by Isaac Newton in 1668. Modern telescopes incorporate advanced detectors to capture images across the electromagnetic spectrum, from radio waves to gamma rays, allowing us to explore the universe's wonders.
