no he used the telescope to observe the moons orbiting Jupiter and satern
Galileo discovered the telescope, and phases of the moon
Galileo discovered the four largest moons of Jupiter and that Venus showed phases like those of the moon.
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.

Well yes and no. The phases of the moon were understood well before Galileo --- however Galileo discovered the moons of Jupiter and no doubt their associated phases --- as well as the phases of Venus.

Galileo discovered two important things: the moons of Jupiter and the phases of venus. Both discoveries raised doubts about the old Ptolemaic system which was geocentric, and the phases of Venus showed that it was definitely wrong. But neither discovery proved that Copernicus's theory - supported by Galileo - was right. This is because Tycho's geocentric system explained the phases of Venus satisfactorily.
Galileo's observations with his telescope supported the concept of heliocentricism. He noted that the satellites of Jupiter and Venus, based on their range of phases, did not match geocentricism supported by Ptolemy. He noted that based on these findings, that the Heliocentric theory was correct.
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.

He built his first telescope and started to make observations. He discovered the phases of Venus and sunspots. He built his first telescope in 1609. Galileo's taught mathematics and actually made a few discoveries in physics. When he heard about the inventor of the telescope and he wanted to improve it.
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.
