Italian Cassini, Giovanni (1625-1712) French-Italian astronomer who measured the period of rotation of Jupiter and issued a table of the motions of Jupiter's moons. He also discovered the moons of Saturn Iapetus Rhea Dione (1684), and Tethys (1684). Cassini discovered that Saturn's rings were divided by a dark gap. He also determined the parallax of Mars which allowed the calculation of the distance to Mars and the Earth Sun distance. Additional biographies: MacTutor (St. Andrews) Firenze Bonn Author: Eric W.

Cassini, Giovanni Domenico Italian-born French astronomer who discovered four moons of Saturn and the gap in the rings of Saturn now called the Cassini division. Cassini was born near Nice (then in Italy). Having assisted two astronomers at an observatory near Bologna, Cassini was made professor of astronomy at the University of Bologna at the age of 25. In 1669 he departed for France at the invitation of King Louis XIV, to construct and run the Paris Observatory. When he went blind 1710, his son Jacques Cassini (1677-1756) succeeded him. During 1664-67 Cassini determined the rotation periods of Mars, Jupiter, and Venus. In 1675 he distinguished two zones within what was thought to be the single ring around Saturn. Cassini correctly suggested that the rings were composed of myriads of tiny satellites. In the 1670s Cassini made many observations of details on the lunar surface. He also took advantage of a good opposition of Mars 1672 to determine the distance between the Earth and that planet. He arranged for Jean Richer (1630-1696) to make measurements from his base in Cayenne, on the NE coast of South America, while Cassini made simultaneous measurements in Paris, which permitted them to make a triangulation of Mars. From the result, Cassini was able to deduce many other astronomical distances.

Free Web space and hosting - wakaf.net Giovanni Domenico Cassini a.k.a. Jean Dominique June 8, 1625 - September 14, 1712 Giovanni Cassini was born on June 8, 1625 in Perinaldo, Republic of Genoa (now modern day Italy). He studied at the Jesuit College in Genoa and then at the Abbey of San Fructuoso. From 1648 to 1669 he observed the skys at Panzano Observatory and, in 1650, he became a professor of astronomy at the University of Bologna. Giovanni observed a comet in 1652-3 and again 1664-5 publishing details of his observations. He had many other interests than astronomy. He was an expert in hydraulics and engineering and was frequently consulted regarding the flooding of the River Po. He was employed by the Pope to oversee fortifications and as an expert on river management. Cassini was eventually invited to Paris by Louis XIV in 1669. The senate of Bologna and the Pope agreed to the trip, which they believed was only to be a short one. However, Cassini became director of the Paris Observatory in 1671, a French citizen two years later, and never returned to Italy. Cassini was the first to observe four of Saturn's moons (Iapetus in 1671, Rhea in 1672, and Dione and Tethys in 1684) after Christiaan Huygens 's initial discovery of Titan in 1655. In 1675, he discovered the gap in the ring system of Saturn that now bears his name and is known as the Cassini division.

9 Cassini, Giovanni Domenico Institutions astronomiques. In 1679, Cassini, the director of the Paris Observatory, published an engraved lunar map that was twice as large as those of Hevelius and Ricciolifully 21 inches across. Based on drawings by Sebastian Leclerc and Jean Patigny, it was markedly superior in detail to its predecessors. Unfortunately, it was only printed as a broadsheet and very soon became unobtainable. However, reduced versions quickly began to appear in various optical and astronomical treatises, replacing, especially in France, the Hevelius and Riccioli maps as the standard. The Library has six different reductions published between 1694 and 1792; the most faithful is this one, included in the first French edition of John Keill's popular treatise on astronomy. Much of the detail of the original Cassini map was lost in the even the best reductions. One of the most delightful features of the 1679 map was the portrayal of Cape Heraclides on the Sinus Iridum (Bay of Rainbows) as a "moon maiden," complete with face and flowing hair. Here, the promontory (8) has become virtually featureless. (For another view of the moon maiden, see item 38.

Giovanni Domenico Cassini (June 8, 1625 - September 14, 1712) Giovanni Domenico (or, in French, Jean Dominique) Cassini was born on June 8, 1625 in Perinaldo (near Nice, now France). He studied mathematics and astronomy at the Jesuits and became professor of astronomy at Bologna, as well as fortress builder, at age 25. There, he determined the obliquity of the ecliptic at 23 deg 29' and studied the effects of refraction and the Solar parallax, worked on planetary theory and observed the comets of 1664 and 1668 (according to Kenneth Glyn Jones, also already one in 1652). Also, in 1663, he worked on fortifying the citadel of Urbino. In 1665, he determined the rotation periods of Jupiter (as 9h 56m) and Mars (24h 40m) with remarkable acuracy, by observing Jupiter's Great Red Spot, discovered by Robert Hooke (1635-1703) in 1664, and moving surface contours on Mars (such as Syrtis Major which Huygens had discovered in 1659). He also observed the phases of Venus, and discovered the oblateness of Jupiter in 1665. On invitation of the French King, Louis XIV, Cassini moved to Paris where he arrived on April 4, 1669, joined the newly founded
