Science and life on Uraniborg

In April 1567, Tycho returned home from his travels, with a firm intention of becoming an astrologer. Although he had been expected to go into politics and the law, like most of his kinsmen, and although Denmark was still at war with Sweden, his family supported his decision to dedicate himself to the sciences. His father wanted him to take up law, but Tycho was allowed to travel to Rostock and then to Augsburg, where he built a great quadrant, then Basel, and Freiburg. In 1568, he was appointed a canon at Roskilde Cathedral, a largely honorary position that allowed him to focus on his studies.

At the end of 1570, he was informed of his father's ill health, so he returned to Knutstorp Castle, where his father died on 9 May 1571. The war was over, and the Danish lords soon returned to prosperity. Soon, another uncle, Steen Bille, helped him build an observatory and alchemical laboratory at Herrevad Abbey, where Tycho was assisted by his keenest disciple, his younger sister Sophie Brahe. Tycho was acknowledged by King Frederick II, who proposed to him that an observatory be built to better study the night sky. After accepting this proposal, the location for the Uraniborg's construction was set on an island called Hven, now Ven in the Sound not too far from Copenhagen, the earliest large observatory in Christian Europe.

Tycho Brahe was highly appreciated by King Frederick II, and he was accepted and supported by people of high social status. He was supported by the church. The support Tycho Brahe received from the king allowed him to continue his research and make significant contributions to the field of astronomy.

In the late 16th century, Tycho Brahe built an observatory called Uraniborg. It was built on the island of Hven located between the provinces of Zealand (Sjælland) and Scania (Skåne). The island was then an administrative part of Zealand. Later, after the Peace of Roskilde in 1658, Scania was conquered by the Swedes. In 1660, Hven became part of Sweden. In Tycho's time, it was all Denmark. He lived on Hven for approximately 21 years. He began to build Uraniborg in 1576 and moved there soon after. As Uraniborg was a significant and advanced observatory, it took years to complete.

Uraniborg was a place where Tycho Brahe could research and analyze his previous findings, as well as explore new discoveries. Tycho Brahe was an astronomer of the pre-telescope era. Using just his naked eye, he observed the planets, moon, stars, and space and recorded everything he saw while completing a multitude of calculations daily. The location of Uraniborg was strategically chosen, with seclusion and support being the primary reasons for building on the island of Hven. Seclusion was essential for accurate observation, and gave Tycho Brahe a better way to focus on his work without worrying about interruptions from other people. Seclusion was also important for observation, as there was nothing interfering with time, light, or motion observations.

Tycho Brahe was a perfectionist, and by being secluded he had complete control over his research and was not limited by anyone else's restrictions, enabling him to develop innovative research. He could focus all of his energy on his work, without receiving any backlash or questioning from anyone. The seclusion gave him the freedom to pursue his research without limitations and paved the way for groundbreaking discoveries in the field of astronomy. Uraniborg was one of the most advanced observatories of its time, equipped with several astronomical instruments, including quadrant instruments, sextants, and astronomical clocks.

Tycho Brahe's observations and calculations at Uraniborg allowed him to develop more accurate solar system models. He compiled the most extensive and accurate catalog of stellar positions up to that time. Tycho Brahe's observations and calculations at Uraniborg allowed him to lay the groundwork for astronomers in the future.

Despite the success Tycho Brahe had on Hven, he eventually left the island after a disagreement with the new king of Denmark, Christian IV. In 1597, Tycho Brahe moved to Prague, where he continued his work and was eventually appointed by Emperor Rudolf II in 1601 as imperial mathematician. However, Uraniborg remained a significant landmark in the history of astronomy.
