He subsequently used his newly invented telescope to discover four of the moons circling Jupiter, to study Saturn, to observe the phases of Venus, and to study sunspots on the Sun. Galileo’s observations strengthened his belief in Copernicus’ theory that Earth and all other planets revolve around the Sun.
What was Galileo researching?
His research — including his observations of the phases of Venus and the fact that Jupiter boasted moons that didn’t orbit Earth — supported the Copernican system, which (correctly) stated that the Earth and other planets circle the sun.

What did Galileo's telescope reveal?
With this telescope, he was able to look at the moon, discover the four satellites of Jupiter, observe a supernova, verify the phases of Venus, and discover sunspots. His discoveries proved the Copernican system which states that the earth and other planets revolve around the sun.
Who was Galileo and what did he discover?
Galileo was a natural philosopher, astronomer, and mathematician who made fundamental contributions to the sciences of motion, astronomy, and strength of materials and to the development of the scientific method. He also made revolutionary telescopic discoveries, including the four largest moons of Jupiter.
What was Galileo's first discovery?
When Galileo pointed his telescope at Jupiter, the largest planet in our solar system, he made a startling discovery. The planet had four “stars” surrounding it. Within days, Galileo figured out that these “stars” were actually moons in orbit of Jupiter.
What were two major achievements in astronomy?
- Archimedes’ principle—— buoyant force = weight of the fluid it displaces.
- Galileo —— (1) telescope for astrophysics; (2) prove that gravitational acceleration is not dependent on weight.
- Newton —— (1) three laws of motion; (2) laws of gravitation.
- Kepler —— three laws of planetary motion.
What effects did Galileo's discoveries have after his death?
What effects did Galileo’s discoveries have after his death? Now able to observe the rotation of planets and confirm Copernican views of the solar system. What contributions did Newton make to scientific knowledge during the Renaissance?
What were two major achievements in astronomy during the Scientific Revolution?Galileo Galilei (1564-1642) improved the telescope, with which he made several important astronomical discoveries, including the four largest moons of Jupiter, the phases of Venus, and the rings of Saturn, and made detailed observations of sunspots.
Article first time published onHow has Galileo's discoveries changed the world?
He helped created modern astronomy In early 1610, he made the first in a remarkable series of discoveries. … While the scientific doctrine of the day held that space was perfect, unchanging environments created by God, Galileo’s telescope helped change that view.
How does Galileo's telescope work?
In Galileo’s telescope the objective lens was convex and the eye lens was concave (today’s telescopes make use of two convex lenses). Galileo knew that light from an object placed at a distance from a convex lens created an identical image on the opposite side of the lens.
What was Galileo's telescope called?
Galilean telescope, instrument for viewing distant objects, named after the great Italian scientist Galileo Galilei (1564–1642), who first constructed one in 1609. With it, he discovered Jupiter’s four largest satellites, spots on the Sun, phases of Venus, and hills and valleys on the Moon.
What was Galileo's childhood like?
Galileo was born in Pisa, Italy where he grew up with his brothers and sisters during the Italian Renaissance. His father was a music teacher and a famous musician. His family moved to the city of Florence when he was ten years old. It was in Florence that Galileo began his education at the Camaldolese monastery.
What was Galileo's personality like?
Personal Traits. Galileo was of average stature, squarely built, and of lively appearance and disposition. Viviani remarks that he was quick to anger and as quickly mollified. His unusual talents as a speaker and as a teacher are beyond question.
What did Nicolaus Copernicus discover?
Nicolaus Copernicus was a Polish astronomer known as the father of modern astronomy. He was the first modern European scientist to propose that Earth and other planets revolve around the sun, or the Heliocentric Theory of the universe.
Who was Galileo's successor?
Evangelista Torricelli moved to Florence to assist the master a few months before his death. He later became Galileo’s successor as Mathematician to the Grand Duke of Tuscany, carrying on Galileo’s research in physics and geometry.
How is Galileo's work used today?
The Telescope While Galileo did not invent the first telescope, he did refine it to the point that he was able to see farther than any telescope of its time. This allowed him to see into outer space as well as set the basis for the kinds of powerful telescopes that we use today.
What is Galileo's microscope?
Galileo built his ‘occhiolino’ in 1609, and Faber was the first to name the ‘microscope’ from the Greek ‘micron’ (small) and ‘skopein’ (to look at). Essentially a modified telescope, Galileo’s microscope used a bi-concave eyepiece and bi-convex objective lens to provide up to 30 times magnification.
How much did Galileo's telescope magnify and what were its limitations?
Improvement to telescope design Galileo’s telescope could only magnify objects 30 times before the image became distorted. It also had a narrow field of view. In 1610 Johannes Kepler began investigations into the way that different combinations of lenses could work together to produce a magnified image.
How much did Galileo's telescope magnify?
Through refining the design of the telescope he developed an instrument that could magnify eight times, and eventually thirty times. This increased magnification of heavenly objects had a significant and immediate impact. These new observations were by no means exclusive to Galileo.
What is a Cassegrain telescope used for?
Cassegrain reflector, in astronomical telescopy, an arrangement of mirrors to focus incoming light at a point close to the main light-gathering mirror. The design was proposed in 1672 by French priest Laurent Cassegrain.
How did people react to Galileo's work?
Many people believe that Galileo was hounded by the church for almost two decades, that he openly maintained a belief in heliocentrism, and that he was only spared torture and death because his powerful friends intervened on his behalf.
What did Galileo's parents want him to study?
During the summer of 1583 Galileo was back in Florence with his family and Vincenzo encouraged him to read Galen to further his medical studies. … Of course he was still officially enrolled as a medical student at Pisa but eventually, by 1585, he gave up this course and left without completing his degree.
