What scientific problem was solved with the invention of the telescope?

Lippershey’s new technology quickly spread all over Europe. Almost immediately, the Italian scientist and inventor Galileo started working to improve Lippershey’s design. In just two years, Galileo had made a more powerful telescope. It could make very distant objects visible to the human eye. The Figure below shows Galileo demonstrating his powerful telescope. It appears to be focused on the moon. Galileo started using his telescope to explore the night sky. He soon made some remarkable discoveries. He observed hills and valleys on the moon and spots on the sun. He discovered that Jupiter has moons and that the sun rotates on its axis. With his discoveries, Galileo was able to prove that the sun, not Earth, is at the center of the solar system. This discovery played an important role in the history of science. It led to a scientific revolution that gave birth to modern Western science.

The scientific problem that was solved when the telescope was invented was to be able to see the stars and other planets we couldn't see before because they were too far away. And it also showed the clear images of earth and the moons.And it was also able to show new nature on each planet and places in space in different ways.
