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!
astronomers had the Earth at the center of theuniverse with other objects moving around it. Workby Galileo and others helped to change this theorywith the more accurate heliocentric model such asJupiters moons, were clearly revolving around somethingother than the Earth.Such a view of the universe differed strongly with thebeliefs of the Catholic Church at the time and putGalileo on trial in 1633, he was forced to withdraw manyof his ideas and even spent the final years of his life underhouse arrest
Q&A1. The challenges that Galileo faced was theChurch didnt believe that earth was the centerof the universe so he went under house arrestFor all his life from 1633.2. I think that the challenges do not still existtoday in NZ but in some other countries I thinkthey still do when, someone disagrees withsomeone else, in countries that do not have freespeech.3. I think the challenges that astronomers face today isthey have to havethe money to research.
