An excerpt from Galileo's Sidereus Nuncius, showing the "Medicean stars." On January 7, 1610 Galileo Galilei pointed a small twenty-power telescope at Jupiter. What he …
When Galileo turned his telescope to observe Jupiter, he saw what he initially thought to be three previously unobserved fixed stars. After continued observations it became clear that they were not fixed, and in a matter of days he had come to the conclusion that these new stars were in fact orbiting Jupiter.
Sidereus Nuncius Galileo's First Jupiter Observations. Sidereus Nuncius, published in 1610, is Galileo's account of his first astronomical observations using a telescope.He found that the surface of the Moon, like Earth, is rough and uneven, that the Milky Way and several nebulas are made up of numerous stars too faint to see individually with the naked eye, and most famously, …

By Jan. 15, Galileo correctly concluded that they were not stars at all but moons orbiting around Jupiter, providing strong evidence for the Copernican theory that most celestial objects did not revolve around the Earth.Jan 9, 2020
Galileo was correct in concluding that the Milky Way was composed of stars, he just had not realized that it could also include gas and dust.
Galileo showed that force causes acceleration. On the basis of the law of parabolic fall, Galileo reached the conclusion that bodies fall on the surface of the earth at a constant acceleration, and that the force of gravity which causes all bodies to move downward is a constant force.
Galileo's laws of motion, made from his measurements that all bodies accelerate at the same rate regardless of their mass or size, paved the way for the codification of classical mechanics by Isaac Newton. Galileo's heliocentrism (with modifications by Kepler) soon became accepted scientific fact.Oct 24, 2019
With his observations of the phases of Venus, Galileo was able to figure out that the planet orbits the Sun, not the Earth as was the common belief in his time.Feb 24, 2009
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?
Describe Galileo's experiments with inclined planes and state the conclusion. By observing the motion of objects on inclined planes, Galileo deduced that objects move with constant speed when no force acts on them.
One result of the experiment surprised Galileo, and one surprises us. Galileo found that the heavy ball hit the ground first, but only by a little bit. Except for a small difference caused by air resistance, both balls reached nearly the same speed. And that surprised him.
Conclusion. All objects, irrespective of their mass, experience the same acceleration g when falling freely under the influence of gravity at the same point on the Earth. Close to the Earth's surface, g=9.8 m s−2.
Italian astronomer Galileo Galilei provided a number of scientific insights that laid the foundation for future scientists. His investigation of the laws of motion and improvements on the telescope helped further the understanding of the world and universe around him.Nov 14, 2017
Galileo discovered evidence to support Copernicus' heliocentric theory when he observed four moons in orbit around Jupiter. Beginning on January 7, 1610, he mapped nightly the position of the 4 “Medicean stars” (later renamed the Galilean moons).Jul 7, 2009
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.Feb 11, 2022
What he observed changed the way we understood the universe. Galileo noticed what appeared to be three small stars near Jupiter.
Right: Robert Janvier's 1764 map of Europe. Galileo realized that since the moons of Jupiter obeyed Kepler's laws, they could serve as a kind of heavenly clock. A clock more precise than any human-made clock of the time. So he began to compile a table of eclipses of the Galilean moons.
He had discovered three of the largest moons of Jupiter. The implications of this discovery, of objects orbiting a planet, were part of what pushed Galileo to argue for a sun-centered cosmos. Jupiter's moons countered a key argument against the Earth orbiting the sun.

The engravings of the Moon, created from Galileo's artfully drawn sketches, presented readers with a radically different perspective on the Moon. Due to Galileo's training in Renaissance art and an understanding of chiaroscuro (a technique for shading light and dark) he quickly understood that the shadows he was seeing were actually mountains and craters. From his sketches, he made estimates of their heights and depths. These observations, only possible by the magnifying power of the telescope, clearly suggested that the Aristotelian idea of the Moon as a translucent perfect sphere (or as Dante had suggested an "eternal pearl") were wrong. The Moon was no longer a perfect heavenly object; it now clearly had features and a topology similar in many ways to the Earth. The notion that the moon had a topology like the Earth led to speculation on what life might be like on the Moon.
His observations and interpretations of stars, the moon, Jupiter, the sun and the phases of the planet Venus, were critical in refining our understanding of the cosmos . In March of 1610, Galileo published the initial results of his telescopic observations in Starry Messenger ( Sidereus Nuncius), this short astronomical treatise quickly traveled to the corners of learned society.
While there is evidence that the principals of telescopes were known in the late 16th century, the first telescopes were created in the Netherlands in 1608. Spectacle makers Hans Lippershey & Zacharias Janssen and Jacob Metius independently created telescopes. The telescope emerged from a tradition of craftsmanship and technical innovation around spectacles and developments in the science of optics traced back through Roger Bacon and a series of Islamic scientists, in particular Al-Kindi (c. 801–873), Ibn Sahl (c. 940-1000) and Ibn al-Haytham (965–1040).
Galileo Galilei (1564-1642) was part of a small group of astronomers who turned telescopes towards the heavens. After hearing about the "Danish perspective glass" in 1609, Galileo constructed his own telescope. He subsequently demonstrated the telescope in Venice.
It's now understood that English astronomer Thomas Harriot, (1560-1621) made the first recorded observations of the Moon through a telescope, a month before Galileo in July of 1609.
Most people in Galileo's time believed that the Earth was the center of the universe and that the Sun and planets revolved around it. The Catholic Church, which was very powerful and influential in Galileo's day, strongly supported the theory of a geocentric, or Earth-centered, universe.
In 1581, Galileo was sent to the University of Pisa to study medicine. While a student at the university, Galileo discovered that he had a talent for mathematics. He was able to persuade his father to allow him to leave the university to become a tutor in mathematics. He later became a professor of mathematics.
Galileo was sentenced to life imprisonment in 1633. Because of his age and poor health, he was allowed to serve his imprisonment under house arrest. Galileo died on January 8, 1642.
After Galileo began publishing papers about his astronomy discoveries and his belief in a heliocentric, or Sun-centered, Universe, he was called to Rome to answer charges brought against him by the Inquisition (the legal body of the Catholic Church).
Kepler's second law says that. a. net forces cause changes in motion. b. planets move fastest when they are closest to the Sun. c. planetary orbits are ellipses with the Sun at one focus. d. the square of a planet's orbital period equals the cube of its semimajor axis. B.
Retrograde motion means that a planet actually stops its forward motion and then moves in reverse, changing its orbit direction around the Sun.
The Sun is located at one focus of a planet's elliptical orbit , and the planet is located at the other focus. C. Elliptical orbits cause a planet to sometimes be closer to and sometimes farther away from the Sun. D. The Sun is located at the center of a planet's elliptical orbit. E.
