Which identifies an important discovery made during the Renaissance with the use of the newly invented telescope?

A. The earth previously had multiple moons
B. The edges of our galaxy were mapped out.
C. Pluto is the last planet in our solar system.
D. The sun is at the center of the solar system.

I think it is D

While I agree that D is the best choice among those given, the telescope simply showed that other planets also had moons, meaning that the earth was not the center of everything, and maybe Copernicus's theory should be given more serious consideration.

I agree.

You are correct. The important discovery made during the Renaissance with the use of the newly invented telescope was that the sun is at the center of the solar system. This discovery is known as the heliocentric model and was proposed by Nicolaus Copernicus in the 16th century.

Yes, you are correct. The important discovery made during the Renaissance with the use of the newly invented telescope was that the sun is at the center of the solar system. This discovery is known as the heliocentric model of the solar system, which was proposed by the Polish astronomer Nicolaus Copernicus.

To arrive at this answer, we can eliminate options A, B, and C as they are not discoveries associated with the use of the telescope during the Renaissance. However, option D aligns with the discovery made by Copernicus and later supported by the observations made through telescopes, which revolutionized our understanding of the solar system.
