What 4 things did Galileo first see when he looked in a telescope?
Galileo looked at the planet Jupiter and observed its 4 largest moons (which are still known as the Galilean moons, to this day).
Who was the first person to find Venus on a telescope?
Venus is easily visible to the naked eye. People were looking at it for millennia before the telescope was invented. Galileo was the first person to look at Venus through 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.
Who discovered the phases of Venus using a telescope?
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.
What is the first documentation of Venus?
The first documentation of Venus was done by Galileo Gallei in 1610. He noticed a bright object in the he sky when looking through his telescope. It was later on, however, that it was known to be Venus.

Who and when was Venus discovered?
Venus is one of the planets that is visible without a telescope. The planet has been known since antiquity. Galileo was the first astronomer to study Venus through a telescope.

How did Galileo contribute to astronomy?
Galileo discovered the sun is the center of the solar system, he improved the telescope, he proved that the moon has craters on it, he claimed Venus has phases, and he observed sun spots on the sun.

Who was the 1st person to examine space through a telescope?
The first person to examine space through a telescope was Galileo Galilei in the early 17th century. He made significant astronomical discoveries, such as the moons of Jupiter and the phases of Venus, which supported the heliocentric model of the solar system.
What is the first documentation of Venus?
The first documentation of Venus was done by Galileo Gallei in 1610. He noticed a bright object in the he sky when looking through his telescope. It was later on, however, that it was known to be Venus.
When finding helped provide evidence that the planets orbit around the sun rather that the earth?
Venus progresses through phases similar to the Moon. (Galileo's improvements to the telescope meant that Venus was visible as a disc rather than a bright spot.)
How did Galileo learn about the universe what was his great discovery about the planets?
Galileo observed that the planets Mercury and Venus pass through phases just like the Moon. The only way this could happen is if they circled the Sun, and not the Earth. Most importantly, he discovered that Jupiter had four moons. In the 1609, Galileo heard about a new invention called a telescope. He decided to build a telescope and use it to look at the Universe. That is just what he did and that is how he learned about the universe.
What astronomer invented the telescope and proved the heliocentric theory?
The popular answer to this question would be Galileo. However, contrary to popular belief Galileo did not invent the telescope. He built his own telescope about a year after their initial creation and later made significant improvements.
What were two observations the Galileo made through his telescope that supported the heliocentric model?
In 1610, Galileo used the telescope to discover four moons revolving around Jupiter.The motion of these moons proved that not everything in the sky revolves around Earth.Galileo's observation of Venus also supported the heliocentric system. Galileo knew that Venus is always seen near the sun. He discovered that Venus goes through a series of phases similar to those of Earth's moon.
