His telescopes was made from another telescope from europe. That telescope was only able to magnify objects 3 times its size, but Galileo’s telescope was able to magnify objects 20 times its normal size. This helped him view space a whole new way like how the sun is the center and not the earth. He also discovered that Venus and Earth’s moon had phase which also helped him with his theory about the heliocentric view. His telescope had discovered more discoveries like Jupiter’s moons (just 4) which were named the Galilean moons. His telescope also found sunspots and he was also able to observe a
