He thought the rings were "handles" or large moons on either side of the planet. He said "I have observed the highest planet [Saturn] to be tripled-bodied. This is to say that to my very great amazement Saturn was seen to me to be not a single star, but three together, which almost touch each other". - Galileo was astounded when he found that the rings he first observed a couple of years earlier had now disappeared. He wrote "I do not know what to say in a case so surprising, so unlooked for and so novel". The rings were, in fact, edge-on from Earth's perspective. Galileo inadvertently became the first person to observe a Saturn ring plane crossing. - Galileo now observes the rings as two half ellipses. He wrote "The two companions are no longer two small perfectly round globes ... but are present much larger and no longer round ... that is, two half ellipses with two little dark triangles in the middle of the figure and contiguous to the middle globe of Saturn, which is seen, as always, perfectly round".

Cassini, Giovanni Domenico (1625-1712) - Italian astronomer who became the director of the Royal Observatory in Paris. He is credited with the discovery of 4 smaller moons of Saturn, and in 1672 calculating a parallax of Mars that resulted in a earth/sun distance that was accepted into the eighteenth century. Chandrasekhar, Subrahmanyan (1910-1975) - Indian-American astronomer who primarily studied white dwarf stars. He established a limit to the amount of mass such a star is capable of having: 1.4 times the mass of the sun. This figure is known as the "Chandrasekhar Limit".

Um 1663 beschäftigte er sich mit der Rotation und der Abplattung des Jupiter sowie der Oberfläche des Mars und den Pahasengestalten der Venus. König Ludwig der XIV, berief Cassini nach Paris um dort die neugebaute Sternwarte zuleiten. Dort entdeckte er vier neue Saturnmonde und untersuchte das Ringsystem des Saturn. Cassini begründete über mehrere Jahrzehnte hinweg eine astronomische Schule, welche von seinen Nachfahren weiter geführt wurde. Erst die französische Revolution von 1793 beendete diese Ära.

Extractions: As it makes its long, lonely journey through the solar system, the Cassini-Huygens spacecraft is carrying more than just science instruments and sophisticated cameras. Keeping the spacecraft company is the result of a NASA campaign a DVD disk placed onboard the spacecraft containing the signatures of more than a half million well-wishers from 81 nations. These signatures of 616,420 people were recorded onto the disk, then strategically tucked into the side of the Cassini spacecraft. The disk is sandwiched by two pieces of aluminum and covered by a specially decorated patch of protective thermal material. To send signatures into space is not a new concept, but it has never been done on such a widespread scale. Traditionally, spacecraft have carried thin aluminum plates containing scaled down signatures of scientists and engineers involved in creating the project. For example, Voyager 1, the farthest human-made object currently traveling on the outskirts of our solar system, carries six such plates and the Galileo spacecraft, now orbiting Jupiter, carries 11. However, such plates could only hold a maximum of about 900 signatures each not enough to fit the signatures of the more than 8,000 people who worked on the Cassini-Huygens mission.

Extractions: [Beitrag vom 5. Juni 2000] Neben den sehr erfolgreichen Interplanetaren Missionen der US-amerikanischen Raumsonden PIONEER und VOYAGER ist die CASSINI-Mission der NASA eines der bedeutendsten Projekte dieser Tage. Obwohl die eigentliche Mission, deren Hauptziel die Erforschung des Planeten Saturn und dessen Mond Titan ist, offiziell erst 1. Januar 2004 beginnt, gibt es eine Reihe von interessanten Fakten, die wir an dieser Stelle im Vorwege einmal näher erläutern möchten: Der Planet Saturn ist aufgrund seiner einzigartigen, sehr umfangreichen Ringstruktur und der Fülle von Monden (zur Zeit sind 31 Satelliten bekannt) eines der interessantesten Objekte in unserem Sonnensystem. Ähnlich dem Jupiter wird Saturn auch in die Klasse der so genannten Gasplaneten eingeordnet. Die Sonde CASSINI besteht aus zwei Einheiten: die eigentliche Sonde und HUYGENS , eine Lande-Einheit für den Saturnmond Titan. CASSINI und HUYGENS sind ein Gemeinschaftsprojekt der NASA und der europäischen Raumfahrtagentur ESA . Die beiden Raumfahrzeuge, die mit rund 5,60 t Gewicht wahre Giganten sind, wurden am 15. Oktober 1997 mit einer Titan IV/Centaur-Rakete von der Cape Canaveral Air Force Station gestartet.
