- TYCHO BRAHE
-
- Tycho Brahe was born on December 14th, 1546 in a town called
- Knudstrup in Scania, Denmark. His early years were filled with pain, as he
- was kidnapped by his uncle and raised in his castle in Tostrup, Scania. His
- education was backed by his uncle, and he went to the University of Copenhagen
- to study law from 1559-1562. It was during this time that Brahe developed a
- love for astronomy. He saw a solar eclipse of the Sun which was predicted for
- August 21st 1560, and he found it fascinating how a prediction of that nature
- could be made. He also developed small globes with the help of some of his
- instructors at Copenhagen. In 1562, Brahe was sent to the University of Leipzeg
- where he studied until 1565. During this period, he made his first astronomical
- observation. He saw an overlapping of Jupiter and Saturn, and saw that the
- almanacs and ephemerides of the time were inaccurate.
- Between 1565 and 1570,
- he traveled Europe, studying at Wittenberg, Rostock, Basel, and Augsburg. During
- this time he gathered astronomical and mathematical instruments, including
- a large quadrant. In 1571, he settled in Scania after inheriting the land of
- his father and uncle and built a small observatory. Here, he discovered a star,
- one which had not been seen, that was brighter than Venus. This supernova in
- the constellation Cassiopeia shocked the scientific community because it suggested
- that the universe was not in fact perfect and unchanging, as it was believed
- to be at the time.
- With the discovery of this "new" star, Brahe dedicated
- himself to astronomy. Frederick II, king of Denmark and Norway, provided Tycho
- with funds to construct and equip an astronomical observatory on the island
- of Hven in 1576. Brahe named this observatory Uraniborg. For 20 years, the
- observatory was the center for astronomical study and discovery in northern
- Europe. In 1577 he proved that the orbit of the comet of 1577 did lay beyond
- the moon. He also charted accurate positions for more than 777 fixed stars.
- He also proposed a modified Copernican system which suggested that the planets
- revolved around the Sun which in turn moved around the Earth, which was stationary.
- Frederick II died in 1588 and his son Christian IV took over as king. Brahe
- lost most of his income as a result. Tycho left Hven and his observatory in
- 1597.
- He was offered a grant to Bohemia from the Holy Roman Emperor Rudolf
- II, who gave him a pension of 3000 ducats and an estate near Prague. He started
- building a new observatory, but died in 1601 before it could be completed.
-
- BraheÆs work was indeed significant. His data that he had accumulated during
- his lifetime was extremely accurate, and it allowed his assistant Johannes
- Kepler to formulate his three laws of planetary motion. He also laid the ground
- work for Sir Isaac Newton. Much of what we know about astronomy is thanks to
- Tycho Brahe. His last words in Prague were, "Ne frustra vixisse videur," or,
- "May I not seemed to have lived in vain." He indeed did not.
