Telescopes

Telescopes are optical instruments that use lenses or mirrors to gather and focus light from distant objects. In the context of space and astronautical engineering, telescopes are used to observe and study celestial objects such as stars, planets, galaxies, and other astronomical phenomena. Telescopes can be ground-based or space-based, with space-based telescopes offering advantages such as clearer images due to the lack of atmospheric distortion and the ability to observe a wider range of wavelengths. Telescopes have played a crucial role in advancing our understanding of the universe and have contributed to major discoveries such as the existence of exoplanets and the accelerating expansion of the universe.
