after the sleeping comes the waking up.

See the way Galileo saw the universe.

This replica of Galileo’s telescope is on display at London’s Space Museum.

With a device like this, Galileo saw things that have changed the way we viewed the universe and our place in it.

He studied the moon, discovered the four major satellites of Jupiter, observed a supernova, verified the phases of Venus, and discovered sunspots.

He also helped prove the Copernican system, which states that the Earth and other planets revolve around the sun.

Before Copernicus’ and Galileo’s work, it was held that the sun revolved around the Earth.
