He saw 4 moons
Galileo looked at the planet Jupiter and observed its 4 largest moons (which are still known as the Galilean moons, to this day).
Galileo discovered the four largest moons of Jupiter and that Venus showed phases like those of the moon.
Galileo did not invent the microscope; he is credited with improving the design of the telescope. Galileo's telescope had a magnification of around 30x, which allowed him to make groundbreaking astronomical observations, such as the moons of Jupiter.
The four largest satellites of Jupiter, known as the Galilean moons (Io, Europa, Ganymede, and Callisto), were discovered by Galileo Galilei in 1610. Using a telescope, Galileo observed these moons orbiting Jupiter, providing evidence against the geocentric model of the universe and supporting the heliocentric model proposed by Copernicus. This discovery revolutionized our understanding of the solar system.
Galileo was able to see only Jupiter's largest moons, Io, Europa, Ganymede, and Callisto, because these moons are the largest and brightest of Jupiter's many satellites. Their size and brightness made them visible using the relatively primitive telescope technology available to Galileo in the 17th century. Smaller moons may have been too faint to be seen with his telescopes.

Galileo was the first to look at the planet Jupiter through a telescope, and to observe the moons of Jupiter (the 4 largest moons are still known as the Galilean moons).

Galileo observed Jupiter's moons and Saturn's rings with the help of telescope
Yes he did. He famously spotted moons around Jupiter using a telescope.

Galileo Galilei, when he trained his new telescope on the sky.
yes he used it when he discovered all the moons of jupiter
Galileo di Vincenzo Bonaiuti d'e Galilei. He found them with his refracting telescope in the year 1600's

The four largest moons - were named as a group after Galileo because of him being the first person to obseve them through his own invention - the telescope.
