Mirrors in Telescopes

Mirrors in telescopes play a crucial role in gathering and focusing light from distant celestial objects. Unlike lenses, which bend light, mirrors reflect it to create clear images. Most telescopes use a large primary mirror to collect light and direct it to a smaller secondary mirror, which then focuses the light into an eyepiece or camera. This design allows for larger apertures, enabling astronomers to observe fainter objects. The curved shape of the mirrors determines how well they focus light, making mirror telescopes effective tools for exploring galaxies, stars, and planets in the universe.
