Question: The International Year of Astronomy (IYA2009) was a year-long celebration of astronomy that took place in 2009 to coincide with the 400th anniversary of the first recorded astronomical observations with a telescope by Galileo Galilei and the publication of Johannes Kepler's "Astronomia nova", a book, published in 1609, that contains the results of the astronomer Johannes Kepler's ten-year-long investigation of the motion of what?

<P0-S0>  One of the most significant books in the history of astronomy, the "Astronomia nova" provided strong arguments for heliocentrism and contributed valuable insight into the movement of the planets. <P0-S1> Astronomia nova (English: "New Astronomy", full title in original Latin: ) is a book, published in 1609, that contains the results of the astronomer Johannes Kepler's ten-year-long investigation of the motion of Mars. <P0-S2>  This included the first mention of the planets' elliptical paths and the change of their movement to the movement of free floating bodies as opposed to objects on rotating spheres. <P0-S3>  It is recognized as one of the most important works of the scientific revolution. <SEP> <P1-S0> The Man in the Moone is a book by the English divine and Church of England bishop Francis Godwin (1562–1633), describing a "voyage of utopian discovery". <P1-S1>  Long considered to be one of his early works, it is now generally thought to have been written in the late 1620s. <P1-S2>  It was first published posthumously in 1638 under the pseudonym of Domingo Gonsales. <P1-S3>  The work is notable for its role in what was called the "new astronomy", the branch of astronomy influenced especially by Nicolaus Copernicus. <P1-S4>  Although Copernicus is the only astronomer mentioned by name, the book also draws on the theories of Johannes Kepler and William Gilbert. <P1-S5>  Godwin's astronomical theories were greatly influenced by Galileo Galilei's "Sidereus Nuncius" (1610), but unlike Galileo, Godwin proposes that the dark spots on the Moon are seas, one of many parallels with Kepler's "Somnium sive opus posthumum de astronomia lunari" of 1634. <SEP> <P2-S0>  The Year was declared by the 62nd General Assembly of the United Nations. <P2-S1>  A global scheme, laid out by the International Astronomical Union (IAU), was also endorsed by UNESCO, the UN body responsible for educational, scientific, and cultural matters. <P2-S2> The International Year of Astronomy (IYA2009) was a year-long celebration of astronomy that took place in 2009 to coincide with the 400th anniversary of the first recorded astronomical observations with a telescope by Galileo Galilei and the publication of Johannes Kepler's "Astronomia nova" in the 17th century. <SEP> <P3-S0> Mysterium Cosmographicum (lit. <P3-S1>  The Cosmographic Mystery, alternately translated "Cosmic Mystery", "The Secret of the World" or some variation) is an astronomy book by the German astronomer Johannes Kepler, published at Tübingen in 1596 and in a second edition in 1621. <P3-S2>  The full title being "Forerunner of the Cosmological Essays, Which Contains the Secret of the Universe; on the Marvelous Proportion of the Celestial Spheres, and on the True and Particular Causes of the Number, Magnitude, and Periodic Motions of the Heavens; Established by Means of the Five Regular Geometric Solids" (Latin: "Prodromus dissertationum cosmographicarum, continens mysterium cosmographicum, de admirabili proportione orbium coelestium, de que causis coelorum numeri, magnitudinis, motuumque periodicorum genuinis & proprijs, demonstratum, per quinque regularia corpora geometrica"). <P3-S3>  Kepler proposed that the distance relationships between the six planets known at that time could be understood in terms of the five Platonic solids, enclosed within a sphere that represented the orbit of Saturn.
