Career Journey and Major Life Events
Early Academic Career
Galileo began his career as a mathematics professor at the University of Pisa and later at the University of Padua. During this period, he conducted experiments on motion and falling objects.
Improvements to the Telescope
In 1609, Galileo improved the design of the telescope. Using his improved instrument, he made revolutionary discoveries:
- Mountains and craters on the Moon
- Four largest moons of Jupiter - Io, Europa, Ganymede, and Callisto
- Phases of Venus
- Sunspots on the Sun
Support for Heliocentrism
Galileo supported Nicolaus Copernicus’s heliocentric model, which stated that the Earth revolves around the Sun. This contradicted the geocentric view supported by the Church.
Trial and House Arrest
In 1633, Galileo was tried by the Roman Inquisition for supporting heliocentrism. He was forced to withdraw his views and was placed under house arrest for the rest of his life. Despite this, he continued his scientific work.
