  10. 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.

  11. 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.

  12. 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.

  13. 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.

  14. 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.
