How Do Telescopes Work?

Telescopes are devices that let people see things that are far away. People at sea also use telescopes. Telescopes are most commonly used to look at space. The inventor of the telescopes was Galileo Galilei. He invented the telescope with eyeglass parts. Telescopes work using light. Light is everywhere! The telescope has two mirrors. They are called concave and convex lenses. These mirrors help produce the image. When the light hits these mirrors (light comes from what you are looking at) it refracts or bends the light into your eyes producing the magnified or close-up image! This is the amazing science of how telescopes can let you see into far-off space.
