  1. Source of Saturn’s kilometric radiation revealed

    Date de publication:

    13 Novembre 2018

    Using data from the Cassini mission, scientists are unravelling the mechanisms that drive auroral radio emissions at Saturn’s poles, which are key to understanding certain characteristics of the giant ringed planet. Laurent Lamy, an astrophysicist at the LESIA space and astrophysics instrumentation research laboratory (Paris Observatory) and lead author of an article on the subject in the journal Science, gives us the details.

  2. Saturn’s north polar hexagon

    Date de publication:

    19 Septembre 2018

    Analysis of data from the Cassini probe has revealed that a vortex towering more than 300 kilometres above Saturn’s north pole mirrors the famous hexagon cloud pattern observed lower in the planet’s atmosphere since 1980. Sandrine Guerlet from the LMD dynamic meteorology laboratory in Paris, who has co-authored a paper on this discovery, explains.

  3. Cassini: Destination Moons

    Date de publication:

    6 Septembre 2017

    In the space of 13 years, Cassini observed Saturn and devoted a lot of attention to its moons. With the mission now about to end, Patrick Michel, astrophysicist, planetologist and research director at the Côte d’Azur Observatory in Nice, reflects on the discoveries it has made about the planet’s natural satellites.

  4. Saturn’s rings through the eyes of Cassini

    Date de publication:

    4 Septembre 2017

    As well as studying Saturn and its moons, Cassini also trained its sights on the planet’s rings, analysing their composition, structure and dynamics to learn more about the physics of these very special features. Sébastien Charnoz, an astrophysicist at Paris Diderot University and research scientist at the IPGP global physics institute in Paris, looks back at what the mission has found.

  5. Cassini’s Saturnian legacy

    Date de publication:

    1 Septembre 2017

    Since entering orbit around Saturn in July 2004, the Cassini spacecraft has studied the planet and its moons from every angle. Before its dramatic dive into the gas giant’s atmosphere and its final demise on 15 September, Thierry Fouchet, a lecturer at Pierre et Marie Curie University (UPMC) and research scientist at the Paris Observatory, reviews its 13 years of discoveries.

  11. Sand dunes on Titan

    Date de publication:

    24 Mai 2006

    The Cassini spacecraft has revealed sand dunes on the surface of Titan, Saturn’s giant moon. The dunes look very similar to those seen in the Namibian desert. They appear to have been sculpted in much the same way as dunes on Earth, even though conditions on Titan are very different.

  12. Huygens: an emotional first encounter with Titan

    Date de publication:

    17 Janvier 2005

    Friday evening, in Paris, a crowd of more than 2,000 filed into the auditorium at the Cité des Sciences et de l’Industrie to witness the arrival of the Huygens probe on Titan. Huygens had already successfully landed at its destination earlier in the day. Now, everybody was eagerly awaiting the first sights and sounds from this distant world over 1 billion km from Earth. One of the first images taken by Huygens. Titan’s surface is darker than scientists expected and is likely a mixture of water ice and hydrocarbons. Crédits : ESA/NASA/University of Arizona

  14. First findings from Cassini-Huygens

    Date de publication:

    1 Octobre 2004

    Early this summer, just days after entering orbit, the Cassini-Huygens spacecraft sent back its first findings from Saturn. Preliminary science results are beginning to shed new light on a complex and fascinating planetary system. Having discovered new satellites and made measurements of unprecedented precision, Cassini’s first weeks at Saturn are already looking very promising.

  15. Huygens set for the big jump

    Date de publication:

    16 Décembre 2004

    Six months after the arrival of Cassini-Huygens at Saturn, mission scientists are gearing up for a new phase. Like a Christmas present tumbling from Santa’s sleigh, the European Huygens probe will be cut loose from the orbiter on 25 December, before diving into Titan’s atmosphere 3 weeks later. Huygens is expected to improve our understanding of Saturn’s largest moon, the only one in the Solar System known to have a dense atmosphere containing organic molecules.

  17. Cassini-Huygens mission- Titan one year on

    Date de publication:

    10 Janvier 2006

    Cassini-Huygens is the 1st space mission dedicated to exploring Saturn and its system of rings and moons. One year ago today, Europe’s Huygens probe separated from the Cassini orbiter and landed on Titan, Saturn’s largest moon. What have its findings taught us about this tantalizing new world?
