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
Galileo was the first astronomer to use what?
Galileo first used a telescope to observe the sky.
How did Galileo use the four moons of Jupiter?
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. :)
The first person to use a telescope for astronomical observation was?
Gallelio was the inventor of the astronomical telescope. He was also the first to use it and the first to observe the mountains on the moon
Which ancient astronomer was the first to use a telescope?
Galileo Gailei is the first person credited with using the telescope for astronomical observations. He did not invent the telescope. He is the first to have seen moons going around Jupiter, the rings of Saturn (though he incorrectly identified them), and that the Moon had cliffs and craters.
