Telescopes became more and more advanced. Today we can watch over 38,000 objects through the more advanced ones of our time. We could clearly see a lot of planets of our Galaxy. The first telescope has been invented by 3 men: Hans Lippershey, Zacharias Janssen and Jacob Metius, in 1608. After 125 years, in 1733, the achromatic lens was invented, which made telescopes more functional. Even though the first telescope was invented in The Netherlands, it got known worldwide today!
