His Life      Tycho Brahe was born on December 14, 1546. He was a Danish nobleman known for his accurate astronomic          <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;">and p <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;">  <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;">lanetary observations. <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;"> He attended the Universities of Copenhagen and Leipzig, he then traveled through the German region to study at the universities of Wittenberg, Rostock, and Basel. This is where his interest in alchemy and astronomy started. Tycho returned to Denmark in 1570. In 1572, he observed the star, Cassiopeia and a year later he published a tract about it. In 1574, he held lectures on astronomy at the University of <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;">Copenhagen. At this point, he was convinced that the improvement of astronomy relied on good observations. He then went on another tour of Germany visiting astronomers. He was granted the funding to build a research institute by King Frederick II on the island of Hven, he named it Uraniborg. He built many astronomical instruments there, took many careful measurements, and made nightly observations. He left the institute in 1597 after a fall out with King Christian IV. In 1599 Tycho became the imperial astronomer of Prague. He built a new observatory there in 1600 of which he worked at until his death in 1601. He was assisted by Johannes Kepler at this observatory. <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;">Later on,   <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;">   Kepler used Tycho's information to develop his own theories on astronomy. As an astronomer, Tycho fused together the geometrical aspects of Copernicus' system and the philosophical aspects of the Ptolemaic system, forming the Tychonic system. Tycho's contributions to astronomy were enormous, he developed new instruments and also a new way of astronomical research. The instruments he created, he also checked for accuracy periodically. He revolutionized astronomical instrumentation. He changed the research of astronomy profoundly. Unlike other astronomers who observed planets at certain points in their orbit, Tycho observed the planets throughout their orbits. Without his observations, Kepler could not have discovered that the planets orbits were elliptical. Tycho was the first astronomer to correct atmospheric refraction. Tycho revolutionized the study of astronomy. <span style="color: rgb(94, 40, 149);"> Tychonic Universe  <span style="color: rgb(94, 40, 149);"><span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;"> <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;">Tycho observed the n <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;"> <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;">ew sta <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;"> <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;">r of 157 <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;"> <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;">2 <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;"> <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;"> <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;"> <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;"> and the comet of 1577 the studies of the two proved the fact that the heavens were changeable, which went against the beliefs of Aristotle and other philosophers. Tycho then started to challenge Aristotle's system. Tycho also figured that if there were comets in the universe, they would have to move through the heavens, which was a lot different from Aristotle's belief that the heavens were unchangeable. Up to now, it had been believed that the planets were carried on material spheres, which were spherical shells, that fit tightly around each other. Tycho's observations proved this hypothesis impossible because the comets moved through these "spheres". Celestial spheres started be less believed in from 1575 and 1625. Tycho's new observations seemed to be more like Copernicus' system, but he did not believe Copernicus' system of a heliocentric universe was completely accurate. Tycho used Aristotelian physics to show that the Earth was the center of the universe, although this went against the technical advantages of Copernicus' system.He developed a system that had the mathematical benefits of the Copernican system, but also the philosophical benefits of the Ptolemaic system. He kept the Earth as the center of the universe, to follow physics and the shell of stars would be centered on the Earth. The Moon and Sun would revolve around the Earth when Mercury, Venus, Mars, Jupiter, and Saturn revolved around the Sun. The Tychonic system became popular early in the 17th Century among those who did not believe in the Ptolemaic system but also did not believe in Copernican system. <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;">
