Tyhco Brahe

• Tycho was a Danish astronomer he became famous for creating precise astronomical measurements of the solar system about 700 hundred stars.

Tyhco Brahe

• During his free time he studied stars, one of his great discoveries was he found a supernova near the Cassiopeia constellation in 1972.

Galileo Galilei

• Galileo (1564-1962) was an Italian physicist and astronomer he is greatly remembered for some of his very important contributions to astronomy and physics. Galileo got a degree in mathematics and taught theories that contradicted Aristotle theories.

Galileo Galilei

• In 1609 he heard that in Holland a spy glass had been invented, and he was inspired to create the first telescope . He also discovered sunspots.

Johannes Kepler

Johannes (1571-1630) was a German natural philosopher and astronomer who was known for his ability in formulating and verifying the three laws of planetary motion. They are known as the Keplers’s laws. He studied theology and classics at the university of Tubingen

Johannes Kepler

Johannes became Tycho Brahe’s assistant at the observatory near Prague. When Tycho passed away, Kelper took over his job and spent the rest of his like writing books.

Clyde Tombaugh

Clyde (91906-1997) is in the astronomers hall of fame. He was the final discoverer of Pluto after he spent may of years researching it. When Clyde was 22 he had made a home made 9 inch reflector which he used to make drawing of Saturn and Jupiter. When he sent in the pictures to Lowell Observatory he was immediately offered a position as a astronomical photographer.

Clyde Tombaugh

Later, his research gained him another position as researcher, and his goal was to find the infamous Planet X, which would later be Pluto.  Finally, on March 12, 1930, Pluto was discovered.

Nicholas Copernicus

Nicholas (1473-1543) was a polish astronomer, he was well known for his Copernican theory. His theory started that the sun rest near the centre of the earth, which spin daily on its axis revolved around the sun. The process is now known as the heliocentric or suncentered system.

Nicholas Copernicus

During the Janurary of 1497 he began to study canon law at University of Bologna while living with a mathematician, Domenico Maria de Novara.  Novara sparked Copernicus' interest in geography and astronomy, and the final climax of it came when the two watched the occultation(eclipse by the moon) of the star Aldebaran on March 9, 1497.

Edmund Halley • During his life he also wrote another important treatise called

Astronomiae Cometicae Synopsis. It was started in 1682 and published in 1705.

 

In this he mathematically demonstrated that comets move in a elliptic orbits around the sun and how over time they would pass the same point.  He had such an accurate prediction that when the comet (now Halley's Comet) returned in 1758, it validated his theory.

Edmund Halley

Edmund (1656-1742) was a British Astronomer, who was the first to calculate a comet's orbit.  He went to the University of Oxford, where he studied the theories of Sir Isaac Newton.  Because he was so interested with the theories, it inspired him to write the Principle which he published with his own money in 1687.

Maria Mitchell

• Maria (1818-1889) is one of the first famous female astronomers. 

• She was born in Nantucket, Massachusetts.  Her love for astronomy began when her father began maintaining a small observatory.  The accomplishment that brought her international reorganization was when she discovered a telescopic comet in October of 1847.

Claudius Ptolemy

• Claudius (AD 100?-170?) was one of the most famous astronomers and mathematicians, even though some of his theories were later proved wrong. Yet he laid down the foundation for future astronomers and mathematicians to take.  His theories dominated the scientific field until the 16th century.

Claudius Ptolemy

His name "Claudius" means 'roman citizenship', but Ptolemaeus means 'resident of Egypt', which would make sense since most of his life was spent in Egypt, specifically Alexandria. Claudius’s most famous work,  Almagest, contained geometric theory which mathematically explained the motions and positions of planets, sun, and the moon against stars that did not move.
