Gallieo Galilei first observed that Venus has phases. This is due, primarily, to the fact that Venus is closer to the Sun than the Earth is. In order to display phases, particularly crescent phases, the observed object must be closer to the Sun than the observer.

∙ 6y agoGalileo Galilei discovered the phases of Venus, by looking at it through a telescope. This happened 400 years ago in 1609, in the Italian city of Padua. He was punished by the church for publishing his observations and forced him to live under house arrest until his death in 1642.

What did Galileo confirm when he discovered the phases of venus and sunspots?
He discovered that interesting results could be obtained by using a telescope.
How did Galileo discover the planet Venus's?
He did not discover the planet Jupiter. He only used his telescope to see its four largest moons. The planet is and always has been visible to the naked eye and was known to people since ancient times.
How did data gathered using Galileo's early telescope support the helioentric model?
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.
What was two discovers that Galileo was able to make by using his telescope to study objects in the sky?
Galileo discovered the four largest moons of Jupiter and that Venus showed phases like those of the moon.
What two discoveries did Galileo make with the telescope?
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.

What was Galileo's influence on the world?
He discovered that Earth was not the center of the solar system, Jupiter has its own moons, and Venus has phases like a moon! He also discovered the rings of Saturn. All this just using one telescope.

What did Galileo dicover by using a telescope?
Galileo discovered stars by using the telescope?
Which is not a discovery made by Galileo using the telescope?
The Amazon River was not discovered by Galileo using a telescope.
Can you see Venus with or without a 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.
What satellite discovered Pluto?
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.
Which planet was discovered in modern times using a telescope?
Uranus
How was Delphinus discovered?
it was discovered by Sir William Herschel on September 24, 1785 using his telescope
