    1. Tycho Brahe!!! By: Olympia Calix Harmony Moore

    2. Interesting Facts!! • Tycho Brahe was born on 14 December 1546 in Sweden. • He was the eldest son of Otto Brahe and BeatteBille, both from families in the high nobility of Denmark. • In a duel with another student, in Wittenberg in 1566, Tycho lost part of his nose. For the rest of his life he wore a metal insert over the missing part.

    3. Interesting Facts (c0ntinued) • 1572- Tycho observed the new star in Cassiopeia and published a brief tract about it in 1753. • He was given the little island of Hven in the Sont near Copenhagen, and there he built his observatory, Uraniburg, which became the finest observatory in Europe.

    4. Death! • One day before he died he kept murmering the words “Ne frustravixissevidear” ( May I not seemed to have lived in vain.) • He died of mercury poisoning in 1601.

    5. Contributions! • Brahe was well known in his lifetime as an astronomer, astrologist and alchemist. • One of his greatest achievements is the observation (naked eye) of the SN 1572 supernova on 11 November 1572 which had unexpectedly appeared in the constellation Cassiopeia. • 1600 until his death in 1601, he was assisted by Johannes Kepler.

    6. C0ntributions! (c0ntinued!) • He believed the sun circled the earth while the other planets circled the sun! • He made the most precise observations that had yet been made by devising the best instruments available before the invention of the telescope. • His observations of planetary motion, particularly that of Mars, provided the crucial data for later astronomers like Kepler to construct our present model of the solar system.

    7. C0ntributions (c0ntinuted) • Brahe made careful observations of a comet in 1577. By measuring the parallax for the comet, he was able to show that the comet was further away than the Moon. • He made the best measurements that had yet been made in the search for stellar parallax. Upon finding no parallax for the stars, he (correctly) concluded that either: the earth was motionless at the center of the Universe, or ,the stars were so far away that their parallax was too small to measure.

    8. His Castle!! • His castle was named Uraniborg. After the Greek Urania! • When Tychorealised he needed even more stability for good observations than provided in the castle and more room for his instruments. • He built an observery built mostly underground, which was named Stjerneborg. (castle of the stars)

    9. Important Information!!! • Brahe invented many instruments such as the TyconianQuadrent!

    10. The layout plan, including the large crypts underground are included in this drawing

    11. Review Questions!! • 1- What instruments did Tycho use to make his astronomical observations? • 2- Evaluate the honest reason on how Brahe died. • 3- What was the castle’s name and who was it named after? • 4- What type of prediction did Tycho make about the orbit of the Solar System? • 5- How did Brahe loose his nose?
