Galileo's Contributions to Astronomy

The video discusses Galileo Galilei's life, his acceptance of heliocentrism, and his conflicts with the church. Despite opposition, he made significant discoveries using a telescope, observing Jupiter's moons, sunspots, and Venus's phases, supporting the heliocentric model.

What was the main astronomical model that Galileo supported?

• Geocentric model

• Heliocentric model

• Flat Earth model

• Ptolemaic model

Why was Galileo's support of the heliocentric model controversial?

• It was a new theory he invented

• It was scientifically proven false

• It contradicted the Church's teachings

• It was not supported by any observations

What was the outcome of Galileo's trial by the Church?

• He was executed

• He was exiled

• He was placed under house arrest

• He was pardoned

What significant tool did Galileo improve to aid his astronomical observations?

• Telescope

• Microscope

• Sextant

• Astrolabe

What did Galileo discover about Jupiter using his telescope?

• It had moons orbiting it

• It was the center of the universe

• It was a star

• It had rings

What did Galileo's observation of Jupiter's moons suggest about celestial bodies?

• They are stationary

• They all revolve around Earth

• They are all the same size

• They can revolve around other planets

What did Galileo observe about the sun that was significant?

• It was the smallest star

• It was stationary

• It had sunspots that moved

• It was a perfect sphere

What did Galileo's observation of Venus reveal?

• Venus is larger than Earth

• Venus has phases like the Moon

• Venus is the center of the universe

• Venus is a star

How did Galileo's observations support the heliocentric model?

• By proving the Earth is flat

• By showing that the sun is stationary

• By demonstrating that celestial bodies can orbit other planets

• By showing that all planets revolve around Earth

What was Galileo's ultimate goal despite his house arrest?

• To prove the Earth was flat

• To prove the heliocentric model

• To become the Pope

• To invent a new telescope
