6 jan 1588 ano - Tycho Brahe

Descrição:

1. In 1572, a new star (now recognized as a supernova) suddenly appeared in Cassiopoeia. Tycho showed that this star was further away than the moon (using parallax?); therefore, a change had occurred in the superlunary realm, contrary to Aristotle. 2. Tycho observed two bright comets in 1577 and 1585; he and others calculated that they, too, were beyond the moon (using parallax), another example of change in the heavens. 3. Tycho also calculated that the comet had apparently crossed planetary orbs; therefore, there could be no solid celestial spheres that carried the planets.
C. Tycho rejected Copernicus’ idea of a moving earth as physically absurd and theologically untenable. In 1588, he presented his own planetary system with the earth at the center, the moon and sun revolving about the earth, and the other planets revolving about the sun.
