Nicolaus Copernicus (19 February 1473 - 24 May 1543) was the first astronomer to formulate a comprehensive heliocentric cosmology, which displaced the Earth from the center of the universe.

Copernicus's model with the Sun at the centre used circles and epicycles, as Ptolemy had done, and claimed his model was simpler, but in fact Copernicus's model needed more epicycles than Ptolemy to represent the planets' positions accurately. Its importance lies in the later use of a heliocentric model by Kepler in discovering the laws of planetary motion.

Galileo Galilei (15 February 1564- 8 January 1642) was an Italian physicist, mathematician, astronomer, and philosopher who played a major role in the Scientific Revolution. He championed Copernicus' heliocentric ideas and contributed to observational astronomy including:-

  • the telescopic confirmation of the phases of Venus
  • the discovery of the four largest satellites of Jupiter (named the Galilean moons in his honor)
  • the observation and analysis of sunspots.

Galileo also worked in applied science and technology, inventing an improved military compass and other instruments.

He did experiments to demonstrate that objects dropped from height would reach the ground together even if they were of different size and mass (obviously this does not apply to objects that float, like feathers).

He also did early pioneering work on dynamics, saying that an object moves in a straight line at constant speed without a force acting on it, which is now generally accepted.

Nicolaus Copernicus discovered that the Sun, rather than the Earth, is the center of our solar system. This heliocentric model replaced the earlier geocentric theory that placed Earth at the center. Copernicus's work laid the foundation for modern astronomy and our understanding of the universe.

Nicolaus Copernicus discoved that the Earth revolves around the sun. This displaced other theories that the Earth was at the centre of the universe and that the Sun revolved around it.
