Isaac Newton was born. Newton developed the Laws of Motion which were used by other cosmologists for the motion of planets and other celestial objects. -
William Herschel
Frederick William Herschel went on to discover Uranus and two of its major moons. -
Pierre-Simon Laplace
Laplace went on to study and predict black holes. -
Percival Lowell
He was known for discovering Asteroid 793 in Arizona. -
Henrietta Leavitt
he made a discovery that allowed other astronomers to correctly judge the distance of Earth to other galaxies. -
William de Sitter
He is known for "de Sitter Universe" -
Albert Einstein
probably the greatest mind of the twentieth century. His Special Theory of Relativity, proposed in 1905, extended Newtonian Mechanics to very large speeds close to the speed of light. It describes the changes in measurements of physical phenomena when viewed by observers who are in motion relative to the phenomena. -
Harlow Shapley
American astronomer who deduced that the Sun lies near the central plane of the Galaxy some 30,000 light-years away from the centre. -
Edwin Hubble
He made an incredible contribution to astronomy and cosmology when he discovered that faraway galaxies are moving away from us. Known as Hubble's Law, the theory states that galaxies recede from each other at a rate proportional to their distance from each other. This concept is a cornerstone of the Big Bang model of the universe. -
Georges Lemaître
He propsed the theory of the expansion of the universe. -
Fred Hoyle
He was known for his contribution to the stellar nucleosynthesis theory. -
Arno Penzias
He was the co-discoverer of the cosmic microwave background radiation, which is radiation left over from the Big Bang. -
Robert Wilson
He was also a co-discoverer of cosmic microwave background radiation left over from the Big Bang.
