He located many other stars too distant to be visible with the naked eye. These financial burdens may have contributed to Galileo's early desire to develop inventions that would bring him additional income. In 1612, having determined the orbital periods of Jupiter's satellites, Galileo proposed that with sufficiently accurate knowledge of their orbits, one could use their positions as a universal clock, and this would make possible the determination of longitude.
From September 1610, Galileo observed that Venus exhibits a full set of phases similar to that of the Moon. By trial and error, he quickly figured out the secret of the invention and made his own three-powered spyglass from lenses for sale in spectacle makers’ shops.  Two years later, Galileo wrote a letter to Christina that expanded his arguments previously made in eight pages to forty pages. Partly because the year 2009 was the fourth centenary of Galileo's first recorded astronomical observations with the telescope, the United Nations scheduled it to be the International Year of Astronomy.
Galileo spent his time to improving the telescope, producing telescopes of increased power. Michelangelo would also occasionally have to borrow funds from Galileo to support his musical endeavours and excursions. The Hale reflector introduced several technical innovations used in future telescopes, including hydrostatic bearings for very low friction, the Serrurier truss for equal deflections of the two mirrors as the tube sags under gravity, and the use of Pyrex low-expansion glass for the mirrors.  Early the next year, he observed the four largest moons of Jupiter. In his 1638 Discorsi, Galileo's character Salviati, widely regarded as Galileo's spokesman, held that all unequal weights would fall with the same finite speed in a vacuum. In 1939, Pope Pius XII, in his first speech to the Pontifical Academy of Sciences, within a few months of his election to the papacy, described Galileo as being among the "most audacious heroes of research... not afraid of the stumbling blocks and the risks on the way, nor fearful of the funereal monuments". He was educated from 1575 to 1578 in the Vallombrosa Abbey, about 30 km southeast of Florence. (It remained for others to re-express the law in algebraic terms). The International Year of Astronomy 2009 was intended to be a global celebration of astronomy and its contributions to society and culture, stimulating worldwide interest not only in astronomy but science in general, with a particular slant towards young people.
This method was pioneered by the ESO New Technology Telescope in the late 1980s. 1608 (Embassy of the King of Siam sent to his Excellency Prince Maurice, arrived at The Hague on 10 September 1608). Galileo further asserted that the parabola was the theoretically ideal trajectory of a uniformly accelerated projectile in the absence of air resistance or other disturbances. The magistrate was contacted by a then unknown claimant, Middelburg spectacle maker Johannes Zachariassen, who testified that his father, Zacharias Janssen invented the telescope and the microscope as early as 1590. Thus, a limited amount of mathematics had long related music and physical science, and young Galileo could see his own father's observations expand on that tradition.. © 2011 American Philosophical Society These observations, together with Galileo's improvement of the instrument, led to the adoption of the name of the Galilean telescope for these early forms of telescope that employed a negative lens. Galileo's instrument was the first to be given the name "telescope".  In adaptive optics, the high-speed corrections needed mean that a fairly bright star is needed very close to the target of interest (or an artificial star is created by a laser). Grassi concluded that the comet was a fiery body which had moved along a segment of a great circle at a constant distance from the earth, and since it moved in the sky more slowly than the Moon, it must be farther away than the Moon. Galileo's discovery of the phases of Venus was thus his most empirically practically influential contribution to the two-stage transition from full geocentrism to full heliocentrism via geo-heliocentrism. This expanded on earlier instruments designed by Niccolò Tartaglia and Guidobaldo del Monte. One of his instruments had an objective measuring 2 1⁄2 inches (6.4 cm) with a relatively short focal length of 20 inches (51 cm). Barberini was a friend and admirer of Galileo, and had opposed the admonition of Galileo in 1616.
To him, it seemed, by comparison with his heartbeat, that the chandelier took the same amount of time to swing back and forth, no matter how far it was swinging. In 2008, Max Tegmark and Matias Zaldarriaga proposed a "Fast Fourier Transform Telescope" design in which the lenses and mirrors could be dispensed with altogether when computers become fast enough to perform all the necessary transforms. With the development of larger arrays and of computers which could rapidly perform the necessary Fourier transforms, the first aperture synthesis imaging instruments were soon developed which could obtain high resolution images without the need of a giant parabolic reflector to perform the Fourier transform. The first telescope Galileo Galilei ever built was made in 1609, just one year after Dutch spectacle-maker Hans Lippershey tried to patent his simple In 1615, Galileo prepared a manuscript known as the "Letter to the Grand Duchess Christina" which was not published in printed form until 1636.
The first record of a telescope comes from the Netherlands in 1608. Gamma rays are absorbed high in the Earth's atmosphere so most gamma-ray astronomy is conducted with satellites. , Dava Sobel argues that prior to Galileo's 1633 trial and judgement for heresy, Pope Urban VIII had become preoccupied with court intrigue and problems of state, and began to fear persecution or threats to his own life. Telescopes seem to have been made in the Netherlands in considerable numbers soon after this date of "invention", and rapidly found their way all over Europe. Galileo's father, Vincenzo Galilei, a lutenist and music theorist, had performed experiments establishing perhaps the oldest known non-linear relation in physics: for a stretched string, the pitch varies as the square root of the tension. Most historians agree Galileo did not act out of malice and felt blindsided by the reaction to his book. The next major development came in 1946 when Ryle and Vonberg (Ryle and Vonberg 1946) located a number of new cosmic radio sources by constructing a radio analogue of the Michelson interferometer. This telescope was world's largest telescope for over 50 years.  Galileo has been called the "father of observational astronomy", the "father of modern physics", the "father of the scientific method", and the "father of modern science"..
These were consequently termed aerial telescopes. In 1845 William Parsons, 3rd Earl of Rosse built his 72-inch (180 cm) Newtonian reflector called the "Leviathan of Parsonstown" with which he discovered the spiral form of galaxies. The book was highly successful and even found support among the higher echelons of the Christian church. The Galileo affair was largely forgotten after Galileo's death, and the controversy subsided. In it he made a point of quoting Acts 1:11, "Ye men of Galilee, why stand ye gazing up into heaven?". The telescope had a small convex hyperboloidal secondary mirror placed near the prime focus to reflect light through a central hole in the main mirror. , A friend of Galileo's, the painter Cigoli, included a realistic depiction of the Moon in one of his paintings, though probably used his own telescope to make the observation. She died on 2 April 1634, and is buried with Galileo at the Basilica of Santa Croce, Florence. Galileo is sometimes credited with the discovery of the lunar libration in latitude in 1632, although Thomas Harriot or William Gilbert might have done it before. The word was meant to be analogous with "telescope". An eminent scholarly organization of international reputation, the American  By 1624, Galileo had used a compound microscope.
