Galileo argued that the Sun was a perfect sphere and that it moves by itself on its own center. The Sun carries these spots until they disappear from view at its rim in about one lunar month. [3] Scheiner's view that the spots were satellites prompts Galileo to comment on the phases of Venus and how they supported a heliocentric view. [30]
JPL built the Galileo spacecraft and managed the Galileo program for NASA, but West Germany's Messerschmitt-Bölkow-Blohm supplied the propulsion module, and Ames managed the atmospheric probe, which was built by the Hughes Aircraft Company. At launch, the orbiter and probe together had a mass of 2,562 kg (5,648 lb) and stood 6.15 m (20.2 ft) tall.
Galileo establishes two main premises before addressing his conclusion. God has created Scripture and nature. They cannot contradict each other. Nature is independent of accommodation, but Scripture is produced to accommodate. [2] Galileo argued that the Copernican theory was not just a mathematical calculating tool, but a physical reality.
For advancing heliocentric theory Galileo was forced to recant Copernicanism and was put under house arrest for the last few years of his life. According to J. L. Heilbron, informed contemporaries of Galileo's "appreciated that the reference to heresy in connection with Galileo or Copernicus had no general or theological significance." [132]
Galileo observed the phases of Venus's appearance with the telescope and was able to confirm Kepler's first law of planetary motion and Copernicus's heliocentric model, of which Galileo was an advocate. [75] Galileo claimed that the Solar System is not only made up of the Sun, the Moon and the planets but also comets. [76]
Galileo did in fact use a telescope, observe the moons of Jupiter, advocate for the heliocentric model, observe sunspots, investigate buoyancy, and write on physics, and did visit the Vatican twice to defend his work, the second time being made to recant his views, and being confined to house arrest thereafter.

It was not until Galileo Galilei observed the moons of Jupiter on 7 January 1610, and the phases of Venus in September 1610, that the heliocentric model began to receive broad support among astronomers, who also came to accept the notion that the planets are individual worlds orbiting the Sun (that is, that the Earth is a planet, too).
