	Tycho Brahe - Wikipedia, the free encyclopedia
		Tycho believed in a modified geocentric model known as the Tychonic system, for the same reasons that he argued that the supernova of 1572 was not near the Earth.
		Tycho was the preeminent observational astronomer of the pre-telescopic period, and his observations of stellar and planetary positions achieved unparalleled accuracy for their time.
		Tycho also worked in the area of weather prediction, produced astrological interpretations of the supernova of 1572 and the comet of 1577, and furnished his patrons Frederick II and Rudolph II with nativities and other predictions (thereby strengthening the ties between patron and client by demonstrating value).

	Tycho (crater) - Wikipedia, the free encyclopedia
		Tycho is a prominent lunar impact crater located in the southern lunar highlands.
		To the south is Street crater; to the east Pictet, and to the north-northeast is Sasserides crater.
		Tycho is a relatively young crater, with an estimated age of 108 million years, as estimated from samples of the crater rays recovered during the Apollo 17 mission.

	Tycho Brahe
		Tycho Brahe, born in 1546, was the eldest son of a noble Danish family, and as such appeared destined for the natural aristocratic occupations of hunting and warfare.
		Tycho lost his temper in a quarrel with another student over who was the better mathematician, this led to a duel in which part of Tycho's nose was cut off.
		Tycho had just finished building a new sextant, with arms five and a half feet long, a massive bronze hinge, a metallic scale calibrated in minutes (sixtieths of a degree) and a table of corrections for the remaining tiny errors in the instrument he had detected.

		Tycho gladly accepted and in 1576 he began the construction of his new observatory — Uranibourg, the ‘Castle of the Heavens.’ It was built in the middle of a large square enclosure, which was laid out as a garden, whose corners pointed north, south, east and west.
		Tycho was a harsh landlord and even built a prison for his tenants which could not pay their rent.
		Tycho observed seven comets in his day correctly stating that they were much more distant then the Moon, thereby disposing of Aristotle’s theory that they were ‘atmospheric exhalations’ only a few miles up.

		Tycho carefully measured its position, then measured it again 12 hours later, when the the rotation of the Earth had moved the observing point to the other side of the Earth.
		Tycho extended such methods to their ultimate limit, the resolution of the human eye, and his star charts were far more accurate than any earlier ones.
		Tycho's manners, however, were arrogant, and the residents of Hven complained about him, so that after the death of the king who was Tycho's patron, Tycho was forced to leave Denmark.

	Tycho Brahe (Site not responding. Last check: 2007-10-22)
		Tycho's reputation as an accomplished astronomer rose quickly, primarily through his observations of and writings on the 1572 Novae in Cassiopea, and of the 1577 comet.
		Tycho demonstrated, perhaps more convincingly than anyone before him, the falsity of the Aristotelian doctrine of the immutability of the Heavens, and of the Aristotelian theory of comets as an atmospheric phenomenon taking place in the sublunar sphere.
		One of Tycho's most impressive astronomical achievement was his discovery of the Moon's so-called annual variation, a variation of the Moon's orbital speed associated with the gravitational pull of the Sun, and which shows an annual periodicity due to the slightly varying distance between the Earth and Sun in the course of the year.

		DAVID O. "Tycho is a well-formed crater in the southern uplands, 54 miles across, with high terraced walls and a central mountain complex.
		Magnificent though it is, Tycho lies in so crowded an area that it would not be outstanding were it not for the rays.
		Near full moon, when Tycho's rays dominate the whole scene, it is tempting to believe that the crater lies at the lunar pole.

	The Galileo Project \| Science \| Tycho Brahe
		Tycho was also the first astronomer to make corrections for atmospheric refraction.
		Tycho's observations of the new star of 1572 and comet of 1577, and his publications on these phenomena, were instrumental in establishing the fact that these bodies were above the Moon and that therefore the heavens were not immutable as Aristotle had argued and philosophers still believed.
		Tycho gave various reasons for not accepting the heliocentric theory, but it appears that he could not abandon Aristotelian physics which is predicated on an absolute notion of place.

	Tycho Brahe Biography (Site not responding. Last check: 2007-10-22)
		Tycho Brahe is probably the most famous observational astronomer of the sixteenth-century, although is not always clear whether he is better remembered for the fact that his data provided the basis for the work of Johannes Kepler (1571-1630), or because of the more colourful aspects of his life and death.
		The appearance in 1572 of a "new star" (in fact a supernova) prompted Tycho's first publication, which was issued by a Copenhagen printer in 1573.
		With generous royal support, Tycho constructed there a domicile and observatory which he called Uraniborg, and developed a range of instruments of remarkable size and precision which he used, with the aide of numerous assistants and students, to observe comets, stars, and planets.

		Tycho had been working on improved instruments for observing for a while, but when in Augsburg he designed some of his own and managed to obtain a patron to underwrite the cost of a major new instrument.
		Tycho closed down his observatory on Hven in 1597 (the last recorded observation is on 15 March that year), and moved to Copenhagen.
		Tycho intended that this work should prove the truth of his cosmological model, in which the Earth (with the Moon in orbit around it) was at rest in the centre of the Universe and the Sun went round the Earth (all other planets being in orbit about the Sun and thus carried round with it).

		Tycho was elected Rector of the University of Copenhagen in 1577, proposed by the theologian Niels Hemmingen, who was in hot water at that time because of the accusation that he was a crypto-Calvinist.
		Tycho himself acted as a patron to a number of students and assistants.
		Tycho was first given his choice of some castles for his work (he chose Benatky), and the emperor later bought the house of the late vice-chancellor Curtius in Prague for Tycho's use at the estimated cost of 10,000 gulden.

	Lunar Orbiter: Impact Crater Geology
		The crater Tycho, 85 kilometers in diameter, is the youngest large impact crater on the Moon's nearside.
		Tycho is in the lunar highlands, and the terrain surrounding the crater is quite rugged.
		Multispectral images obtained by the Clementine spacecraft show that the central peak has a different composition than the surrounding material, presumably because the central peak is composed of material that originated at greater depths in the Moon's crust.

	The Straight Dope: Did astronomer Tycho Brahe really have a silver nose?
		Tycho Brahe (1546-1601), the father (or at least the godfather) of modern astronomy, really did wear an artificial nose, owing to the fact that the real one had been sliced off in a duel.
		There Tycho constructed an observatory where for 20 years he compiled the impressive body of astronomical data that his assistant Johannes Kepler subsequently used to deduce the laws of planetary motion.
		To give you a further indication of the type of guy we're dealing with there, Tycho didn't marry the mother of his eight children, employed a dwarf as a jester, kept a pet elk (which died after breaking a leg while going downstairs drunk), dabbled in alchemy, and tyrannized the local peasantry.

		These two colorful characters made crucial contributions to our understanding of the universe - Tycho's observations were accurate enough for Kepler to discover that the planets moved in elliptic orbits, and his other laws, which gave Newton the clues he needed to establish universal inverse-square gravitation.
		Tycho Brahe (1546-1601), from a rich Danish noble family, was fascinated by astronomy, but disappointed with the accuracy of tables of planetary motion at the time.
		Tycho died the next year, Kepler stole the data, and worked with it for nine years.
