Telescopes have allowed us to see further than the naked eye would ever allow. With the invention of the telescope by Hans Lipperhey, mankind has discovered new planets, constellations and threats to our planet such as comets or meteors. Telescopes have also been one of the main reasons that man has begun to explore space, we see things out there worth discovering and taking a closer look at.
Galileo Galilei
I believe you are confusing two things here; there is no such thing as a "heliocentric model of telescope". There is a heliocentric model of our Solar System, and there are telescopes. The two are unrelated.
the first to formulate a comprehensive HeliocentrismCosmology, which displaced the Earthfrom the center of the Universewas Nicolaus Copernicus
Usually it's simply called a "solar telescope, but there are other names such as "helioscope" (specialising in sunspot observation).
"Our solar system." The "part of our galaxy" that's in our solar system is the solar system.
The Solar System I believe...
Galileo.
He was famous for improving the telescope and for believing that the earth was not the center of the solar system, but that the sun is.
A telescope.
by inventing the refraction telescope to look out into space
Galileo
Galileo had a theory, it was that the earth was NOT in the centre of the solar system like everyone thought, he made the first telescope and proved everyone wrong by looking into space and seeing that the sun was in the centre of the solar system, not the earth, doing this he also invented the telescope.
Nicolas Copernicus did not use a telescope, the use of the telescope to study the solar system was not done until over 50 years later by Galileo.
Galileo was the first astronomer to use a telescope to observe celestial objects in detail. This helped him make groundbreaking discoveries such as the moons of Jupiter and the phases of Venus, which provided strong evidence for the heliocentric model of the solar system.
Why, the telescope, of course! Using his telescope, Galileo was able to make observations of the heavens in a way no one else was able to before.
Galileo was the first person to use a telescope for astronomical purposes, making significant observations that supported the heliocentric model of the solar system. His astronomical discoveries, such as the moons of Jupiter and the phases of Venus, revolutionized our understanding of the universe.
Galileo discovered the sun is the center of the solar system, he improved the telescope, he proved that the moon has craters on it, he claimed Venus has phases, and he observed sun spots on the sun.
