Galileo's Contributions to Astronomy

The video discusses Galileo's contributions to astronomy, including his improvements to the telescope and his support for the heliocentric model of the solar system. It highlights his observations of Venus and Jupiter, which challenged the prevailing Aristotelian views. Galileo's work laid the groundwork for future scientific advancements, despite facing opposition from the church and academia.
