He is also the credited inventor of the telescope. If no force acts on a moving object, it will maintain the same speed and direction The Polish astronomer Nicolaus Copernicus had proposed a Sun-centered universe some 70 years earlier, but his model had failed to completely take hold. The individual became an anonymous, interchangeable robot who had little chance on the job to demonstrate his personal qualifications for upward mobility into the echelons of management. After hearing about the "Danish perspective glass" in 1609, Galileo constructed his own telescope. Because hydrogen fusion is never ignited in the center of a brown dwarf, the brown dwarf's _____ steadily decreases over time after it is born. One of the things that Galileo could not observe with his rudimentary telescope was the rotation of the stars, it is the fact that the stars rotate around their axis. One of the unacceptable notions was that of the imperfect Earth existing in the realm of the perfect heavens. All these observations were direct evidence that supported the Heliocentric model proposed by Copernicus. When Kepler began his work, which solar system model was able to make the most accurate predictions? Outside the western tradition of science. What Galileo also invented was the Celatone which was a device that he used to find the longitude on earth. Galileo sparked the birth of modern astronomy with his observations of the Moon, phases of Venus, moons around Jupiter, sunspots, and the news that seemingly countless individual stars make up the Milky Way Galaxy. At only 24 years old, he briefly became an instructor at the Academy of Arts of Drawing in Florence before returning to Pisa as the chair of mathematics the following year.

This design, however, went unbuilt until after the construction of the first working pendulum clock by Christiaan Huygens. Another stated that it was a belt of compressed fire. Of all of his telescope discoveries, he is perhaps most known for his discovery of the four most massive moons of Jupiter, now known as the Galilean moons: Io, Ganymede, Europa and Callisto.
