Johannes Kepler worked as an assistant to the observatory of Brahe at the age of 27.Brahe collected astronomical observations, which were passed into Kepler, on his death.Among the significant contributions of Brahe:1. His observations on the planetary motion of Mars were used by later astronomers, includingKepler to construct the present model of the solar system.2. In 1572, he observed supernova as a star that appeared suddenly, became visible for 18months before it faded from view. Nowadays, supernova is called an exploding star.3. In 1577, he observed a comet by measuring its parallax. His claim contradicted the idea ofAristotle that comets are "gases burning in the atmosphere." By measuring the parallax forthe comet, he was able to show that the comet was further away than the Moon.4. His findings that stars do not have parallax, he concluded that either: (a). the earth wasmotionless at the center of the universe; or (b). the stars were so far away that their parallaxwas almost negligible to measure.5. Brahe proposed a model of the Solar System that was intermediate between the Ptolemaicand Copernican models (it had the Earth at the center). It proved to be incorrect, but was themost widely accepted model of the Solar System for a time.Although, some of the ideas of Brahe were not always correct and acceptable, thequality of his observations led to the development of modern astronomy.Part 2: Each statement has a missing word, write the appropriate word to complete the thoughtof the statement.
