The four moons were discovered sometime between 1609 and 1610 when Galileo made improvements to his telescope, which enabled him to observe celestial bodies more distinctly than had ever been possible before.
As a result of improvements Galileo Galilei made to the telescope, with a magnifying capability of 20×, he was able to see celestial bodies more distinctly than was ever possible before. This allowed Galilei to discover sometime between December 1609 and January 1610 what came to be known as the Galilean moons.

When did Galileo use the telescope to observe moons?
He was the first to see Jupiter's four largest moons: Ganymede, Callisto, Europa and Io.These four are now called the Galilean moons in his honor.
Did Galileo use a telescope to observe the phases of Jupiter?
no he used the telescope to observe the moons orbiting Jupiter and satern
What four discoveries did Galileo make to show planets physical bodies are like earth?
in 1609Galileo became one of the first people to use a telescope to observe objects in space. Galileo discovered craters and mountains on the earths moon four of Jupiter's moons sunspot on the sun and the phases of Venus. these but are physical bodies like the earth.
Who observed - and with what - four moons orbiting Jupiter and phases of Venus in the 1600s?
Gallileo Gallilei observed moons of Jupiter and phases of Venus in the early 1600's using a telescope. This led him to deduce that the Solar System was helio-centric, as opposed to the commonly held Earth-centric position of the times. This placed him at odds with the Roman Catholic church, which, at that time, did not tolerate scientific views which opposed religious dogma of the times.
Who used a telescope to make detailed observations of the stars ad planets?
Galileo Galilei used a telescope to make detailed observations of the stars and planets. He is most well known for suggesting that the Earth revolves around the Sun, and not the other way around.

Are there moons orbiting planet Jupiter if so when were they discovered?
Jupiter has a whole lot of moons including four big ones discovered by Galileo in the 16th century. He was the first one to use a telescope to study Jupiter. Other than those four, all the others are small and were discovered when spacecraft were sent to Jupiter in the 1970s.
Who discovered the largest 4 moons of Jupiter?
Galileo discovered them. Their names are: Io, Callista, Europa and Ganymede. He discovered them in January 1610. == ==Galileo Galilei in 1610.
Did Galileo Galilei use a telescope?
Yes he did. He famously spotted moons around Jupiter using a telescope.
What did Galileo use a telescope for?
He used it to study the moon, Jupiter's moons, Saturn, Venus and the sunspots on the sun.
How do you use Galileo in a sentence?
Galieo was the first astronomer to view Jupiter's moons through a telescope and proved the heliocentric model.

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.
