A Danish nobleman, Tycho Brahe (1546-1601), made important contributions by devising the most precise instruments available before the invention of the telescope for observing the heavens. Brahe made his observations from Uraniborg, on an island in the sound between Denmark and Sweden called Hveen.

Nicolaus Copernicus was a Polish astronomer known as the father of modern astronomy. He was the first modern European scientist to propose that Earth and other planets revolve around the sun, or the Heliocentric Theory of the universe.

His work continues to help astronomers study everything from gravitational waves to Mercury's orbit. The scientist's equation that helped explain special relativity – E = mc^2 – is famous even among those who don't understand its underlying physics.

He subsequently used his newly invented telescope to discover four of the moons circling Jupiter, to study Saturn, to observe the phases of Venus, and to study sunspots on the Sun. Galileo's observations strengthened his belief in Copernicus' theory that Earth and all other planets revolve around the Sun.

Hawking was the first to set out a theory of cosmology explained by a union of the general theory of relativity and quantum mechanics. He was a vigorous supporter of the many-worlds interpretation of quantum mechanics.

His research helped prove that the universe is expanding, and he created a classification system for galaxies that has been used for several decades.

Though Kepler is best known for defining laws regarding planetary motion, he made several other notable contributions to science. He was the first to determine that refraction drives vision in the eye, and that using two eyes enables depth perception.

Newton was one of the first to make a reflecting telescope. However, his most profound contribution to science is the formulation of three Laws of Motion, described in Philosophiae Naturalis Principia Mathematica in 1687, which also lays the foundation for the principle of universal gravitation.

He believed that the Earth was the center of the Universe. The word for earth in Greek is geo, so we call this idea a "geocentric" theory.
