Galileo first used the telescope to view the Moon in 1609, shortly after he heard about the invention of the telescope in the Netherlands. He constructed his own version of the telescope and made his observations from his home in Padua, Italy. His detailed observations of the Moon revealed its rugged surface and craters, challenging the prevailing notion of its perfection.
The first modern astronomer to view Mercury using a telescope was Galileo Galilei in the early 17th century. His observations of Mercury, along with other planets, helped to revolutionize our understanding of the solar system.
I suspect the answer you're looking for is Galileo Galilei. It just has two problems: Galileo didn't "invent the telescope", nor did he "develop a heliocentric view of the universe." The telescope was invented in the Netherlands; Galileo simply improved on it and was probably the first to apply it to astronomical observations instead of just looking for distant ships. Also, Copernicus is (properly) credited with the heliocentric view; Galileo's observations supported this, but he didn't come up with it.
In the early 17th century
Galileo made several important discoveries with his telescope, including the four largest moons of Jupiter (now known as the Galilean moons), the phases of Venus, sunspots on the Sun, and mountains and craters on the Moon. These observations provided evidence to support the heliocentric model of the solar system and challenged the geocentric view of the universe.
The telescope was invented to allow astronomers to view distant objects in space more clearly. It revolutionized the field of astronomy by enabling scientists to observe celestial bodies such as stars, planets, and galaxies in more detail, leading to numerous discoveries and advancements in our understanding of the universe.
Galileo Galilei was the first person to view the moon with a telescope in November 1609. His observations revolutionized our understanding of the moon's surface and helped to lay the foundation for modern astronomy.
Galileo was the first scientist to see the features of the moon. He did this in 1609 by using an early version of the telescope. Galileo was able to make out some of the pits and mountains on the moon.
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.

The first man to view the craters of the Moon through a telescope was Galileo Galilei in 1609. His observations revealed the Moon's surface features, including craters and mountains, challenging the prevailing belief that the Moon was a smooth, perfect sphere. Galileo's findings were significant in advancing the field of astronomy and laid the groundwork for modern scientific observation of celestial bodies.
Galieo was the first astronomer to view Jupiter's moons through a telescope and proved the heliocentric model.

No. One of his major contributions was the improvement of telescope technology which allowed him to be the first human being to view many astronomical phenomena for the first time.

It didn't - the planet Saturn was observed in ancient times, but Galileo was the first to view it through a telescope and discover its rings in 1610.
