  Fact
   

Telescopes


Although scientists are not certain, it is considered that Hans Lippershey (1570-1619) is the inventor of this extraordinary device. However, the first to use a telescope for astronomical purposes was the Italian scientist Galileo Galilei, in 1609. He was the first to see the craters of the moon and to discover the sunspots, four of the moons of Jupiter and Saturn's rings. In 1704 the reflector telescope was designed by Sir Issac Newton- the concept was that instead of lens, mirrors could be used in the telescope. This was the concept that was used when the Hubble telescope was created in 1985. It was launched on 25 April 1990 and made many unbelievable discoveries.
