There he builds an astronomical observatory with a paper mill and printing press.  ·  1584- He constructed a model of the solar system, which places the earth at the center of the universe, with the sun revoloving around the earth, and the planets revolving around the sun. He named it the Tychonic system.  ·  1596- Tycho is accused of many offenses and is forced to leave his island observations.  ·  <span style="font-size: 12pt; font-family: 'Times New Roman','serif'; mso-fareast-font-family: 'Times New Roman';">1597- He makes his last observation on the Island on March 15.

 * Dates of His Life**

**His Main Beliefs and Achievements** <span style="font-size: 12pt; font-family: 'Times New Roman','serif'; mso-fareast-font-family: 'Times New Roman';">Tycho Brahe made a remarkable star catalogue of over 1000 stars. He proved that comets are not objects in the atmosphere. He showed irregularities in the moons orbit. His wall quadrant and other instrument became widely copied and lead to improved stellar instruments. He observed the new star in Cassiopeia and the Comet. In the Tychonic system, he believed the Earth was the immobile body around which the sun revolved, and the five planets revolved around the sun. He published //<span style="font-size: 12pt; font-family: 'Times New Roman','serif';">De mundi aetherii recentioribus phaenomenis, //<span style="font-size: 12pt; font-family: 'Times New Roman','serif';"> the second volume of a projected three-volume work on his astronomical observations. **His Quote** <span style="font-size: 12pt; font-family: 'Times New Roman','serif'; mso-fareast-font-family: 'Times New Roman'; mso-ansi-language: EN;"> [|“With a firm and steadfast mind one should hold under all conditions, that everywhere the earth is below and the sky above, and to the energetic man, every region is his fatherland.”]

** How His Work Affects Us Today ** All Tycho Brahe's observations were made before the telescope was invented. All of his observations were seen through the naked eye. His devices were used for measuring angles and positions. Clocks were not invented yet either, so he used the movements of the stars and planets with accurate results. Since he did all his observations through the naked eye, they were a start point of ideas of how the earth, sun, and planets revolved around each other.

HERO Tycho Brahe was a brilliant astronomer and scientist of his time. His biggest achievement was the accomplishment of a precise and systematic basic astronomical research. He made a star catalogue. He proved that comets are not objects in the atmosphere. He showed irregularities in the moons orbit. His wall quadrant and other instrument became widely copied and lead to improved stellar instruments. He observed the new star in Cassiopeia and the Comet. He made up the Tychonic system where the Earth was the immobile body around which the sun revolved, and the five planets revolved around the sun. He published //De mundi aetherii recentioribus phaenomenis.// He created the Tycho Brahe calendar.

Awarded ** "The father of the modern art of observation." **  WANTED Reward for his capture is $100,000. He didn’t believe in the geocentric system idea. The geocentric idea is that the Earth is in the center of the universe and the other planets revolved around the Earth. He believed in his own Tychonic system where the Earth was the immobile body around which the sun revolved, and the five planets revolved around the sun.
