Year 11 Physics “Telescopes” Telescopes have had a long history, with the first known telescope being built in 1608, which is almost 400 years ago. The patent application called the telescope a device for seeing faraway things as though nearby. Galileo made the telescope famous, and in the early 1600s, he even discovered four of Jupiter's moons. Soon after, telescopes started getting longer, because the ways to improve the focusing abilities of telescopes were either to lengthen the telescopes or to use mirrors. A "reflecting telescope" using mirrors wasn't invented until Newton did so in the 1670s.
