Galileo is well known for modifying the telescope and making it functional to view the stars and planets in the night sky. Since then, several improvements have been made to the telescope. In the 18th century, The King of England granted Sir William Herschel to build a telescope with a 12 meter focal length and a 120 cm mirror.]]> 2020-02-21 15:08:18 UTC https://padlet.com/garcizuz000/dw4w95tcpm1/wish/448621717
