Copernicus
The heliocentric model is the one that replaces the geocentric model because the heliocentric model better described the solar system.
Aristotle
The planets in our solar system revolve around the sun
Astronomers conclude that objects in the universe are moving away from Earth due to the observed redshift in their spectra. This supports the idea of an expanding universe, as described by the Big Bang theory. The amount of redshift is proportional to the distance of the object, allowing astronomers to estimate the speed at which galaxies are moving away from us.
They are both ancient astronomers where Kepler concluded with his three law ant Brahe did also play a role in geocentric and heliocentric universe. Check the history about Martina's Luther, Galileo, Christopher and you will find the whole theory.

EARLY astronomers primarily used mathematics; that's why so many "early astronomers" are described as "mathematician and astronomer". Until the invention of the telescope in the early 1600's, there were no astronomical tools beyond the octant.
Nicolaus Copernicus and Galileo Galilei were pivotal figures in the development of heliocentric theory, but their relationship was indirect due to their different timelines. Copernicus proposed the heliocentric model in the early 16th century, which laid the groundwork for later astronomers. Galileo, who lived a century later, provided critical observational evidence supporting Copernicus's ideas through his telescopic discoveries. While they did not interact personally, Galileo's work built upon and validated Copernicus's revolutionary concepts.

Copernicus and later Galileo and Kepler. Venus was found to have phases Jupiter was found to have moons Elliptical orbits which Kepler found would later be described by gravity Start there.
A comet is often described by Astronomers as a 'Dirty Snowball'. This is because a comet comprises of Ice, from frozen gases mixed with dust and other particulate matter, collected on its orbital path.
The discovery of the crab nebula, a supernova remnant, seems to correspond to a bright supernova recorded by Chinese astronomers in 1054. The nebula was later described by John Bevis in 1731.
