Galilieo found a way to improve it. he made a three-powered spy glass. But it wasnt good enough to see distant things. So he taught him self the art of lens grinding and increasenly made it more powerfull that it can magnife up to 20 times. He later discovered the moon was rough. In 1610 he found 4 moons of jupiter, stars that were invisible to the naked eye and saturn and its rings. He later discovered that all palanets orbit the sun not the earth.
