2. Galileo facts
• Galileo was a astronomer, physicist, mathematician,
philosopher and inventor. Among his inventions
were telescopes, A compass and a thermometer.
• With his telescopes, Galileo was able to observe the
skies in ways previously not achieved. in 1610 he
made observations of 4 objects surrounding Jupiter
that behaved unlike stars, these turned out to be
Jupiter’s for largest satellite moons: Io, Callisto,
Europa and Ganymede. They were later renamed
the Galilean satellites in honor of Galileo himself!
3. astronomers had the Earth at the center of the
universe with other objects moving around it. Work
by Galileo and others helped to change this theory
with the more accurate heliocentric model such as
Jupiter's moons, were clearly revolving around something
other than the Earth.
Such a view of the universe differed strongly with the
beliefs of the Catholic Church at the time and put
Galileo on trial in 1633, he was forced to withdraw many
of his ideas and even spent the final years of his life under
house arrest
4. Q&A
1. The challenges that Galileo faced was the
Church didn't believe that earth was the center
of the universe so he went under house arrest
For all his life from 1633.
2. I think that the challenges do not still exist
today in NZ but in some other countries I think
they still do when, someone disagrees with
someone else, in countries that do not have free
speech.
3. I think the challenges that astronomers face today is
they have to have
the money to research.
