What did Galileo discover?

A:

Quick Answer

After Galileo built his first telescope in 1609, he observed and described the landscape of the moon, discovered four of the moons of Jupiter, discovered the phases of Venus, and discovered sunspots. Galileo's discovery of sunspots supported the idea of heliocentrism, a model that places the sun at the center of the universe with the planets orbiting around it.

Galileo studied and later taught mathematics at the University of Pisa. He helped to describe ballistics and presented his "Principle of Inertia." In 1632, Galileo presented his concept of basic relativity in physics, which later became the basis of Einstein's special theory of relativity.

In 1632, Galileo published a book openly supporting heliocentrism. He was later forced to publicly denounce his findings.

  • Q:

    Why was Galileo important?

    A:

    While he did not invent the telescope, Galileo modified one of the devices before discovering a number of planets and moons, including Venus, which inspired a scientific revolution. His contention that Copernicus was correct about a heliocentric galaxy drew the ire of the Vatican, which believed the Earth was at the center of the galaxy. Galileo later published his findings, which resulted in his imprisonment.
