That's a really broad category, but one of the biggest changes was probably the invention of the telescope. Telescopes have allowed astronomers to observe the stars with increasing accuracy and eventually allowed them to prove that the Sun, no the Earth, was the center of the solar system. I would recommend researching Copernican and Ptolemic models of the universe to get a better idea of the two different interpretation of the structure of the universe and then you can maybe go from there. The biggest thing that telescopes helped prove years after Copernicus' time was interstellar parallax -- basically that the stars we see from Earth move back and forth rather than spinning around us, so you might want to look that up, too. :)

How fare is the sun from earth?
At different times of the year, Earth is different distances from the sun because the Earth's orbit around the sun is like an oval so the distances change. When Earth is the closest to the sun, it is 147 million km (91,341,565 miles). When Earth is farthest from the sun, it is 152 million km (94,448,421 miles).

What is the relationship of the sun's position to vernal equinox?
The equinoxes are considered to mark the beginnings of the spring and autumn astronomical seasons. The astronomical seasons are heavily promoted by the mass media, but are no more "official" than any other method of reckoning seasonal change. The World meteorological Organization designates March 1 and September 1 respectively as the first days of spring and autumn. The ecological spring begins locally with the start of the growing season which can be as early as February and as late as May in temperate climates depending on latitude and topography. The ecological autumn begins locally when the leaves on deciduous trees change colour and start falling to the ground.
