  1. Source of Saturn’s kilometric radiation revealed

    Date de publication:

    12 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. Cassini reveals giant dust storms on Titan

    Date de publication:

    5 Octobre 2018

    These giant dust storms seen at the equator on Titan rise as far as 10 kilometres above the surface. Mars and Earth are no longer the only worlds in the solar system where such phenomena are known to occur. We put three questions to Sébastien Rodriguez, a planetologist at the IPGP global physics institute in Paris and lead author of this discovery published in the journal Nature Geoscience on 24 September.

  3. 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.

  4. Cassini- Tracking Saturn’s great storm

    Date de publication:

    3 Janvier 2018

    A giant storm raged in Saturn’s atmosphere from 2010 to 2011. To understand the effects of this planetary-scale disturbance, scientists pored over the 13 years of data from the Cassini spacecraft to analyse temperatures and wind dynamics. We talk to Sandrine Guerlet, research scientist at the LMD dynamic meteorology laboratory and co-author of an article on this subject in the journal Nature Astronomy.

  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.

  6. L’héritage de Cassini sur Saturne

    Date de publication:

    1 Septembre 2017

    Depuis sa mise en orbite autour de Saturne en juillet 2004, la sonde Cassini a pu étudier la planète et ses satellites sous tous les angles. Avant son plongeon et sa destruction dans l'atmosphère de la géante gazeuse le 15 septembre, retour avec Thierry Fouchet, professeur à l’UPMC et chercheur à l’Observatoire de Paris sur les découvertes qu’elle y a réalisées 13 ans durant.

  7. Science teams to the fore

    Date de publication:

    31 Juillet 2008

    Every 2 years, CNES’s COSPAR report reviews advances in space science research. The latest report was given to attendees at the 37th COSPAR Scientific Assembly held in Montreal, Canada, 13-20 July. It is also available for download (see links).
