One major problem with the refractor telescope used by Galileo was sagging lens.
The telescope
Galileo was the first to use a telescope for major discoveries, around the year 1610.
The invention of the Telescope by Galileo.
Probably Galileo Galilei (Astronomer and Physicist, 1564 -1642)
No. One of his major contributions was the improvement of telescope technology which allowed him to be the first human being to view many astronomical phenomena for the first time.
The telescope,In 1609, Galileo was the first person to use a telescope to observe the skies (after hearing about Hans Lippershey's newly-invented telescope). Galileo discovered the rings of Saturn (1610), was the first person to see the four major moons of juipiter(1610), observed the phases of Venus studied sunspots, and discovered many other important phenomena.It also helped us learn more about are solar system (:
Galileo Galilei is one of the most famous astronomers in history. One of his major accomplishments was the improvements he made to the telescope. Galileo is known for greatly advancing the scientific revolution.
His Father, for he didn't want Galileo to major in mathmatics, but to major in medicine instead.
toothpaste
Galileo Galilei (15 February 1564 - 8 January 1642) was a Italian physicist, mathematician, astronomer, and philosopher who played a major role in the Scientific Revolution. His achievements include improvements to the telescope and consequent astronomical observations, and support for Copernicanism. Galileo has been called the "father of modern observational astronomy", the "father of modern physics," the "father of science," and "the Father of Modern Science."
Galileo was important because he stated that the sun was center and all other planets moved around it. Galileo supported the theory of heliocentrism, which was antithetical to the doctrines of the Catholic Church, which maintained that the sun revolved around the earth. Galileo played a crucial role in the Renaissance because he helped to break the tyrannical grip that the church held over common people.
Newton did not invent the telescope, he invented the reflecting telescope. The reflecting telescope was a major improvement over the distorting refracting telescope.
