Telescopes

Telescopes are optical devices that focus and magnify images, allowing us to see distant objects more clearly. The first documented telescope, was patented in 1608 by Hans Lippershey, a spectacle maker from the Netherlands. The following year, Galileo Galilei created his own version and made his own astronomical observations. Since then, telescopes have become far more sophisticated and can detect wavelengths invisible to us, enabling us to see celestial objects billions of light years away.
