Or that one reason Galileo's theories were not completely accepted was that he insisted that the orbits of the planets were perfect spheres, which they were not? Or that Copernicus' theories were accepted by the Church as a hypothesis that required further proof?catholic.net Or that astronomy and science were not "held back"? Jesuit astronomers include Cassini, among many others. "He developed a method of mapping successive phases of solar eclipses, published new tables of the Sun, and elaborated on the first major theory of atmospheric refraction founded on the sine law (Dictionary of Scientific Biography, vol. 3, 1971, p. 101). He formulated a new theory on cometary orbits. He obtained powerful new telescopes and embarked on detailed studies that resulted in important findings about Mars (spots on Mars and the planet's period), Jupiter (the revolution of the satellites and rotation of the planet; spots, bands and flattening at the poles). In his early forties, Cassini accepted a position to help set up the Paris Observatory. There he remained for the rest of his career. He pushed continually for the observatory to acquire the latest technology and to use recent inventions and improvements. Substantial funding was won to purchase instruments. His own studies focused on the Moon, Mars, Jupiter, comets and planetary and satellite orbits. He discovered Iapetus, Rhea, Tethys, and Dione. In 1675, he discovered that Saturn's rings are split largely into two parts by a narrow gap -- known since as the "Cassini Division.""jpl.nasa.gov Or that the Church admitted its errors with respect to Galileo?cs.rutgers.edu
