He discovered that interesting results could be obtained by using a telescope.
Galileo discovered the phases of Venus, which helped support the heliocentric model proposed by Copernicus. By observing Venus through a telescope, Galileo was able to see that its phases changed over time, providing evidence that Venus orbits the Sun, not Earth.
None of it but Galileo's discoveries with the telescope were very important in raising questions about the old Ptolemaic theory, which was geocentric. However Galileo's discovery of Venus's phases was not a proof of the heliocentric principle because Tycho produced a geocentric model that explained Venus's phases.
Galileo discovered the four largest moons of Jupiter and that Venus showed phases like those of the moon.
He Discovered that Earth was not the center of the solar system , Jupiter Has four moons and Venus has light and dark phases, like a moon! He also discovered the rings of Saturn. All this using just one telescope? Galileo didn't invent the telescope, but he was the first person we know of to point a telescope into the skies - and discovered that Jupiter wasn't just a bright light in the sky, but was an enormous planet with moons of its own. The four largest are called the "Galilean" moons; Ganymede, Europa, Callisto and Io.

Galileo discovered stars by using the telescope?
Galileo Galilei was the first astronomer to make extensive use of the telescope for astronomy. He made several important discoveries, such as the moons of Jupiter and the phases of Venus, using his telescope in the early 17th century.
The Amazon River was not discovered by Galileo using a telescope.
Uranus, which was discovered by Sir William HerschelPrior to the invention of the telescope, the only known planets were Mercury, Venus, Earth, Mars, Jupiter, and Saturn.Uranus was the first planet discovered by telescope.
Yes. Venus is one of the brightest objects in the night sky, second only to the moon, and can easily be seen without a telescope. Using a telescope will not reveal much detail, as the surface of Venus is masked by dense clouds.
No satellite did. Pluto was discovered by Clyde Tombaugh, who found it using a ground-based telescope in 1930, long before we launched the first satellites.
